Esim Guides

Changing phones can be stressful if your mobile service depends on an eSIM. Carrier eSIMs are more likely to support transfer between phones. However, travel eSIMs are often more restricted and may be tied to the first device they were installed on. This guide explains how to transfer an eSIM to a new phone, when a transfer is possible, what happens to the old device, and what to do if the QR code does not work. Can You Transfer an eSIM to a New Phone? You may be able to transfer an eSIM to a new phone if it is a regular carrier eSIM. Many travel eSIMs should be treated as non-transferable unless the provider or setup notes confirm otherwise. A carrier eSIM linked to your normal mobile number may transfer through iPhone, Samsung, Google Pixel, or carrier activation tools. This depends on the phone model, operating system, carrier support, region, and whether the old phone is still available. A travel eSIM or international eSIM is usually more restricted. For instance, if you are moving a dedicated Europe eSIM between devices mid-trip, you might run into activation limits.  If this is a TravelKon travel eSIM that has already been installed, do not delete it from the old phone before checking the activation email, product page, or our support guidance. Situation What It Usually Means What to Do Next You are moving your normal phone plan Transfer may be available Use device settings or contact your carrier You are moving a travel eSIM Transfer may not be supported Check the activation email first You already deleted the eSIM Reinstallation may not work Contact support with your order details Your new phone will not scan the QR code The code may already be used Stop rescanning and ask support Your old phone is lost, wiped, or traded in Transfer may need provider help Contact the carrier or eSIM provider Important: Keep the eSIM installed on the old phone until the new phone is connected and working. If the eSIM is a travel eSIM, deleting it too early may prevent reinstallation. Quick Checklist Before Transferring an eSIM to a New Phone Before attempting an eSIM transfer, check the following: Carrier eSIM vs Travel eSIM vs Data-Only eSIM Feature Carrier eSIM Travel eSIM Data-Only eSIM Uses your normal phone number Usually Usually not Usually not Transfer supported Often Sometimes Depends on the provider QR code reusable Depends on the carrier Often no Depends on the provider Calls and SMS Usually Depends on the plan Usually no Carrier assistance available Yes Provider specific Provider specific Risk of losing access after deletion Lower Higher Medium As mentioned earlier, while a local carrier plan might allow multi-device shifting, a prepaid Japan travel eSIM bought for a short holiday is typically locked to the hardware of your initial device.  How to Transfer eSIMs Across Different Phone Brands Moving your eSIM profile to a new device varies significantly by manufacturer, so select your specific brand setup below: Transferring an eSIM from iPhone to iPhone If your carrier supports eSIM Quick Transfer, use these steps to move your profile across seamlessly. Prerequisites: Procedure: After a successful transfer, the eSIM is automatically deactivated or removed from the old device. If the option does not appear, your carrier, region, or iOS version may not support Quick Transfer. Do not delete your old eSIM before contacting your provider. How to Transfer an eSIM from Android to iPhone While cross-ecosystem transfers require specific software support, many major carriers allow direct Android-to-iPhone migration natively during device setup. Note: This direct feature requires a compatible Android device and an iPhone running iOS 26 or later. If your carrier or region doesn’t support native cross-platform switching, you will need to log into your carrier’s app or website to generate a traditional activation QR code. How to Transfer an eSIM from iPhone to Android Moving a profile from iOS to Android no longer requires a manual carrier intervention, provided both devices are updated and your network provider supports direct cross-platform migration. Travel eSIM Tip: Automated device-to-device switching is typically restricted to major post-paid consumer networks. If you are using a prepaid travel or roaming eSIM, do not attempt this method; you must check the provider’s app to see if your original activation profile can be reused. How to Transfer an eSIM Between Samsung Phones On Samsung Galaxy devices: Some carriers may require a new activation instead of a direct phone-to-phone transfer. If you are using a travel eSIM, treat SIM Manager as a settings area, not a guarantee that transfer is supported. Confirm transfer support before removing the old profile. How to Transfer an eSIM on Google Pixel On Google Pixel: Pixel eSIM transfer support depends on the phone model, Android version, carrier, and region. A transfer option for a regular carrier plan does not automatically apply to a travel eSIM. What is the Difference between eSIM Transfer and eSIM Reinstall?  Transferring an eSIM means moving an active profile from one phone to another through supported device, carrier, or provider tools. On the other hand, reinstalling means using the QR code or manual activation details again on another phone. With global eSIM adoption expanding by 30% this year alone, surging from 1.2 billion in 2025 to 1.5 billion active connections worldwide, understanding this distinction is more critical than ever. Many eSIM troubleshooting problems happen because travellers assume transfer and reinstall mean the same thing. For regular carrier eSIMs, transfer may be supported through phone settings or carrier activation. For many travel eSIMs, the QR code may be single-use. Step-by-Step Checklist Before You Transfer an eSIM Use this checklist before deleting, resetting, or rescanning anything. 1. Confirm What Type of eSIM You Have Start by identifying whether the eSIM is: 2. Check whether the New Phone Supports eSIM Do not rely only on the phone name. Different models, regions, and carrier variants can behave differently. Check for an EID in your phone settings. On many phones, this sits

You can keep your usual phone number safe while travelling overseas by leaving your Australian SIM or eSIM installed, using a travel eSIM for mobile data, and keeping data roaming turned off on your home line unless your carrier plan includes suitable roaming. Maintaining this connection is crucial for overseas travellers, given that our phones now act as the primary gatekeepers for banking verification codes, WhatsApp, airline updates, and work logins. According to the ABS, Australians made more than 8.4 million overseas trips between 2024 and 2025, so ensuring your SIM setup is configured correctly before departure is beyond important. A Quick Overview of Travel Number Safety  To keep your phone number safe while travelling overseas: This setup keeps your regular number separate from your overseas data and reduces the risk of roaming charges, account lockouts, and avoidable setup issues. What Keeping Your Phone Number Safe Actually Means Keeping your phone number safe while travelling means two things. First, it means keeping the number working. You may need it for calls, SMS, WhatsApp, iMessage, banking apps, email, airline apps, accommodation bookings, and password recovery. Second, it means protecting the number from avoidable risks. These include accidental roaming charges, lost phone issues, SIM swap scams, carrier account takeover, account lockouts, public Wi-Fi risks, and deleting the wrong eSIM. Your phone number belongs to your home mobile service. A travel eSIM is usually a separate mobile data plan. If it is data-only, it gives your phone internet access but does not usually provide a normal phone number for calls and SMS. Item What it controls Home SIM or eSIM Your usual phone number, calls, SMS, and carrier account Travel eSIM Overseas mobile data Apps WhatsApp, iMessage, banking, email, password manager, airline apps Travel eSIM vs Roaming vs Local SIM Option Keeps the usual number? Data cost risk Best for Travel eSIM + home SIM kept installed Yes Low if set correctly Most travellers Home carrier roaming plan Yes Medium to high, depending on plan Short trips where convenience matters Local physical SIM Sometimes no, if the home SIM is removed Low for data, but number access can be harder Longer stays Wi-Fi only Yes, but only when connected Low Light users or backup only VoIP or number parking Depends on setup Low Long-term travellers or expats For most Australian travellers, the cleanest setup is: home SIM for your number, travel eSIM for data. Check out our guide to how an eSIM works to see exactly how easy it is to configure before you head to the departure gate.  Five-Minute Safety Check Before Departure Most eSIM problems are easier to fix before you leave than after you land. 1. Confirm Your Phone Supports eSIM Check that your exact phone model supports eSIM. Some devices vary by country, model version, or carrier. 2. Check That Your Phone Is Unlocked A carrier-locked phone may not accept a travel eSIM. If you are unsure, check with your Australian carrier before leaving. 3. Save Your Setup Details Offline Save: Take screenshots as well. Airport Wi-Fi is not the best time to discover your QR code is stuck inside an inbox that will not load. 4. Check whether the eSIM Is Data-Only If the eSIM is data-only, use it for internet access. Do not expect normal calls and SMS unless the product details clearly say they are included. This is a common feature for regional data packages, such as a multi-country Europe eSIM, which provides seamless internet across borders but can, at times, skip traditional voice minutes.  5. Check Banking and Account Recovery Open your banking apps, email, password manager, airline apps, accommodation apps, and two-factor authentication tools before departure. Where possible, add: Do not rely only on SMS codes if you are unsure whether your home number can receive SMS overseas. Safe Setup vs Risky Setup Safe setup Risky setup Travel eSIM used for mobile data Home SIM left on for roaming data The home number kept installed Home eSIM deleted by mistake QR code saved offline QR code is only stored in email Support contacted before deleting eSIM eSIM deleted during troubleshooting Banking recovery checked before departure SMS recovery assumed to work overseas Mobile lines labelled clearly Home and travel lines left unnamed Mobile data switching turned off Phone allowed to switch back to home data Carrier account protected with a PIN or secure login Carrier account left easy to access Most eSIM problems become harder when the wrong line is selected, the QR code cannot be accessed, or the eSIM is deleted too early. How to Set Up Your Phone iPhone Samsung Google Pixel and Other Android Phones Note: Menu wording varies by device, but the goal is to always use the travel eSIM for data and the home line is protected from roaming data. This setup is particularly useful when using US eSIM plans, as North American networks rely heavily on LTE and 5G data bands for app-based communication rather than older GSM lines.  App and Account Access While Travelling App or service Will it keep working? What to check WhatsApp Yes Keep your existing WhatsApp number. Do not re-register unless you want to change numbers. iMessage Usually yes Check Send & Receive settings before departure. Avoid changing number settings overseas. FaceTime Yes Confirm Apple ID and number settings before leaving. Banking apps Usually yes over data Check SMS code requirements and backup login options. Email Usually yes Make sure you know the password and recovery method. Airline and hotel apps Usually yes Log in before departure and save bookings offline. Two-factor authentication Depends on method Authenticator apps and backup codes are safer than SMS-only recovery. How to Protect Your Phone Number From Theft and Fraud Overseas As mentioned earlier, keeping your number safe is not only about mobile data settings. It also means protecting the phone, SIM, carrier account, and recovery methods linked to that number. Your phone number can also be targeted through SIM swap attempts or carrier account takeover, particularly

If you deleted your eSIM and the QR code now says already used, expired, or invalid, you may not be able to reinstall it without provider support. In some cases, a deleted eSIM can be reinstalled using the original QR code or manual activation details. In others, the installation credentials can only be used once, meaning a replacement eSIM may be required. This guide explains when you can reinstall a deleted eSIM, when you cannot, and the fastest way to get connected again. Once you are done here, check out our deep-dive blog on how an eSIM works to master the basics.  Quick Answer You may be able to reinstall an eSIM after deleting it, but you should never assume the original QR code will work again. Before attempting another installation: If the eSIM is still installed but not connecting, do not delete it. Most travel eSIM issues are caused by network selection, roaming settings, activation timing, or mobile data configuration rather than the eSIM itself. The Most Important Thing to Know Deleting an eSIM is not the same as restarting a connection. According to industry projections by the GSMA, 50% of all smartphones will rely on eSIM technology by 2028. However, while the technology is spreading rapidly, actual consumer understanding of how to manage digital profiles lags behind. If your eSIM is still installed on your device, troubleshooting your internal settings is always safer than removing the profile. The vast majority of travel connection failures are caused by minor setup oversights, including: Deleted Your eSIM at the Airport? Do This First If you have already landed and accidentally deleted your eSIM, follow these steps before buying another plan. Can I Reuse the Same eSIM QR Code? Whether the same QR code can be used again depends on the provider and plan. Situation Can You Reinstall? eSIM still installed but switched off Yes eSIM deleted and QR code supports multiple installs Yes eSIM deleted and QR code is single-use Usually no eSIM transferred to another phone Depends on the provider QR code says already used Support is usually required QR code says expired Support is usually required Plan has already finished Usually no Device is carrier-locked Usually no, unless unlocked first For many travel eSIMs, deleting the profile removes the installed mobile plan from the device. If you accidentally remove a single-use Bali eSIM while on holiday, you will likely need a replacement QR code from your provider to get back online.  Is the eSIM deleted or Just Turned Off? Before trying to reinstall anything, check whether the eSIM is actually gone. On iPhone, go to Settings > Mobile or Settings > Cellular. If the travel eSIM still appears as a line, it has not been deleted. It may simply be turned off or not selected for mobile data. On Android, check SIM Manager, Connections, Mobile Network, or Network & Internet. The wording varies by device. If the eSIM is still visible: Turning an eSIM off keeps the profile on the phone. Deleting it removes the profile from the device. Turning Off vs Deleting vs Removing After Travel Action What It Does Safe During Travel? Turning off the eSIM Keeps the eSIM profile on your phone but disables the line Yes, usually safe Deleting the eSIM Removes the eSIM profile from the phone No, avoid unless the plan is finished Removing after travel Deletes the profile once you no longer need the plan Yes, usually fine Resetting network settings Refreshes phone network settings without deleting the eSIM profile Usually safer than deleting How to Reinstall a Deleted eSIM on iPhone If your provider allows reinstallation, follow these steps: If the QR code says it has already been used, has expired, or cannot be activated, stop and contact support. Common iPhone Installation Errors This QR Code Is No Longer Valid This usually means the installation credentials have already been used or have expired. Unable to Complete Cellular Plan Change This can be caused by activation restrictions, network issues, or provider limitations. Cellular Plan Cannot Be Added Check device compatibility, carrier lock status, and whether the installation details are still valid. How to Reinstall a Deleted eSIM on Android Android settings vary by manufacturer, but the general process is: Depending on your device, the menu may appear under: If the phone cannot add the eSIM, check that the device supports eSIM and is not carrier-locked. Common Android Installation Errors Couldn’t add eSIM This may indicate a compatibility issue, poor internet connection, or expired credentials. Code Already Used This usually means the provider does not allow the installation details to be reused. Network Not Activated This often means activation has not completed or the supported destination network has not yet been reached. For example, an Indonesia eSIM may show this status until your flight lands and the device connects to a local Jakarta or Bali carrier.  Manual eSIM Installation Details Explained Some providers include manual installation details as well as a QR code. These may include: These details perform the same function as the QR code and allow the phone to download the eSIM profile directly. On iPhone, you can usually enter these details via Add eSIM > Use QR Code > Enter Details Manually. On Android, the option is typically available during the Add eSIM process. The exact wording varies by device. Manual installation may help if your camera cannot scan the QR code, but it will not always bypass single-use installation rules. What If the QR Code No Longer Works? QR Code Already Used This usually means the QR code has already been used to install the eSIM profile. Some providers allow reuse, but many travel eSIMs do not. QR Code Expired Some installation credentials expire after a certain period. If this happens, support may need to review the order and provide updated instructions. Unable to Add eSIM Possible causes include: Unsupported deviceCarrier-locked phoneIncorrect activation detailsTemporary activation issueExpired or already-used credentials eSIM Installed, but No Data If the eSIM installs

Deleting an eSIM removes the mobile plan profile from your phone. Your phone is not damaged, and your photos, apps, contacts, messages, passwords, and files remain safe. The problem is connection loss. If the travel eSIM was providing mobile data, calls, or SMS, those services may stop working on that device until the eSIM is restored, reissued, reinstalled, or replaced. Even as eSIMs scale to 6.7 billion global connections by 2030, the technology remains somewhat restrictive. Some deleted travel profiles can be reinstalled, while others cannot, making it vital to check with your provider before making any moves.  eSIM Deletion Effects at a Glance  If you delete an eSIM: Important Warning Before You Troubleshoot Do not delete an active travel eSIM as a troubleshooting shortcut unless support specifically tells you to. Our guide to how an eSIM works can help you understand the setup, but if mobile data is not working, it is usually safer to check roaming, mobile data selection, network settings, and activation instructions first. Deleting the eSIM can make a fix harder if the activation link only works once. Deleting an eSIM vs Turning Off an eSIM Many people delete an eSIM when they only meant to turn it off temporarily. Action What Happens Can It Usually Be Reversed? Turn eSIM Off Profile remains stored on the phone but is inactive Yes Delete eSIM Profile is removed from the device Depends on the provider Expired eSIM Profile remains but the plan has ended Service generally cannot be used Factory Reset eSIM may be removed depending on reset choices Depends on device and provider If the eSIM still appears in your phone settings, it may only be switched off but if it has disappeared completely, it has likely been deleted. Will deleting an eSIM Cancel My Plan? Not necessarily. Deleting an eSIM removes the profile from your device, but it does not automatically cancel the service behind it. For example: Always treat phone settings and account billing as separate things. If charges are your concern, contact the provider directly. Can You Get a Deleted eSIM Back? Sometimes, but never assume it. If the eSIM can be reissued, the provider may send a replacement QR code, manual installation details, or a new activation link. If the eSIM was single-install only, the original activation method may no longer work. Before buying another plan, check the original installation email or order page. If the QR code or activation link says it has already been used, stop trying and gather the key details support will need: your order details, device model, destination, screenshots, and a short timeline of what happened. Will deleting an eSIM Delete My Phone Number? In most cases, no. Deleting an eSIM removes the mobile profile from the device, not the phone number itself. eSIM Type What Happens to the Number? Data-only travel eSIM Usually, no phone number is attached Carrier eSIM with mobile number The number remains with the carrier Business or enterprise eSIM The number remains active unless the service is cancelled If the deleted eSIM carried your primary mobile number, you may temporarily lose calls and SMS on that device until the profile is restored. This applies whether you are using a local carrier plan at home or a specific Indonesia eSIM that came bundled with a temporary local virtual number.  What If I Deleted the Wrong eSIM? First, do not delete any other SIM profiles. Check which line is still active in your phone settings. Look for labels such as Primary, Personal, Business, Travel, Secondary, or the destination name. If your home line is still installed, keep it active for calls or SMS where possible. And if you accidentally removed your Japan eSIM instead of an old expired profile, connect to Wi-Fi and verify which profile has been removed before making further changes. This is also why clear SIM labels are important before travelling.  Can I Transfer a Deleted eSIM to a New Phone? Usually not directly. An eSIM profile stored on one phone cannot always be moved like a physical SIM card. Some carriers support eSIM transfer between devices, but many travel eSIMs are designed for one device and one installation only. If you are changing phones, selling a phone, or replacing a damaged device, check the provider’s transfer rules before deleting the eSIM from the old device. For instance, if you upgrade your device while travelling with a US eSIM plan, you will typically need to contact support to reissue the profile for the new hardware.  That said, always assume you may need provider support or a replacement plan unless the instructions clearly say transfers are supported. What Happens If You Delete an eSIM Before or During Travel? Before Travel Deleting a travel eSIM before departure can remove the profile before it has ever connected overseas. This is risky because some travel eSIMs only activate properly after arrival, while the installation code may still be single-use. During Travel Deleting an eSIM overseas is more urgent. If the eSIM was your main data connection, maps, ride-share apps, translation tools, emails, banking checks, hotel bookings, messaging apps, and hotspot sharing may stop working unless you have Wi-Fi or another SIM available. After Travel Deleting an expired travel eSIM after your trip is usually low risk. Still, it can be worth keeping the profile for a few days after returning home in case you need support, receipts, usage checks, or order details. How to Check Whether an eSIM Is Deleted or Just Turned Off Before contacting support, confirm whether the eSIM has actually been removed. On iPhone On Android Note: Menu names vary between Android brands, operating system versions, and regions. What to Do After Deleting an eSIM Situation Likely Cause Recommended Action eSIM deleted before departure Profile removed before activation Check reinstallation eligibility eSIM deleted overseas Active travel profile removed Connect to Wi-Fi and contact support eSIM appears in settings Profile only disabled Turn the eSIM back on QR code says already used Single-use

If your eSIM is stuck on activating, it does not always mean the eSIM has failed. In many cases, the eSIM has been installed correctly but has not connected to the destination network yet. This is common with travel eSIMs, especially when the plan only starts after the phone reaches a supported overseas network. The key is to work out whether the eSIM is still installing, waiting for activation, connected to the wrong data line, blocked by phone settings, or affected by a device or network issue. Quick Answer An eSIM is usually stuck activating because the eSIM profile has not finished installing, the phone has not connected to the destination network, or mobile data is still assigned to the wrong SIM. If the eSIM appears in your phone settings, do not delete it straight away. First, check: Always remember that most activation issues can be fixed without removing the eSIM. Do This First: The 5-Minute Fix Try these steps before changing advanced settings: If the eSIM is visible in settings, avoid deleting it unless the product instructions or support team tell you to. What You See and What It Usually Means What You See What It Usually Means First Thing to Check eSIM says activating before departure The plan may need the destination network before it fully starts Check the product instructions and wait until arrival eSIM is installed but has no data Mobile data, roaming, APN or network selection may be wrong Set mobile data to the travel eSIM QR code says already used The eSIM profile may already be installed or the QR code may be single-use Check SIM settings before rescanning No supported network appears The phone may not be connecting to the correct local carrier Try manual network selection Phone shows SIM not supported The device may be carrier-locked Check carrier-lock status Data works briefly then drops Network selection, APN, VPN, private DNS or automatic switching may be involved Turn off VPN/private DNS and check the selected data line eSIM line is visible but switched off The profile is installed but disabled Turn the eSIM line on iPhone still says activating but data works The label may not have refreshed properly Test data, then restart the phone Is the eSIM Actually Stuck? Not every activating message means something is broken. There are two different stages: A travel eSIM may install before departure but only activate properly once you arrive in the destination country. If you are still in Australia, your Europe eSIM profile won’t be able to connect to its required overseas network yet.  If the eSIM appears in your phone settings, it is usually installed. The issue is more likely to be mobile data selection, roaming, APN, network selection, local coverage or device compatibility. If the eSIM does not appear in settings, the installation may not have completed, as understanding how an eSIM works means knowing the digital profile must be fully downloaded to be visible. Return to the original setup instructions before scanning the QR code again.  Why This Matters for Overseas Travellers Travel eSIM setup is now a normal part of pre-flight planning. Australian residents recorded 910,450 short-term overseas return trips in March 2026, up 8.4% from March 2025, according to the Australian Bureau of Statistics. For travellers, the risk is simple. If the travel eSIM is not selected for mobile data, the phone may keep trying to use the home SIM, connect to expensive roaming, or fail to connect at all. Many travel eSIMs are data-only plans, meaning they are built for mobile data rather than standard calls and SMS unless the product clearly says otherwise. A data-only travel eSIM is usually suitable for maps, WhatsApp, Messenger, email, web browsing, and ride-share apps. This is incredibly handy whether you are using a Japan eSIM to navigate transit apps in Tokyo, or relying on a UK eSIM to map out London’s Tube network.  Australian telcos must provide international roaming usage alerts, including alerts at 50%, 85% and 100% of included roaming pack usage. A travel eSIM helps reduce accidental home-SIM data use only when mobile data is assigned to the correct eSIM line. Before leaving the airport, test maps, messaging, browser access, transport apps and banking apps on mobile data. It is much easier to fix eSIM setup while airport Wi-Fi is still available. Step-by-Step eSIM Troubleshooting Checklist Follow these steps in order. Change one setting at a time, then test mobile data before moving to the next step. 1. Check whether the eSIM Is Installed Open your phone’s SIM or mobile service settings. On iPhone, go to: Settings > Mobile ServiceorSettings > Cellular On Android, go to: Settings > Connections > SIM ManagerorSettings > Network & Internet > SIMs If the travel eSIM appears as a mobile line, it is installed. The issue is likely related to data settings, roaming, APN, destination coverage or network selection. If it does not appear, return to the original installation email and product instructions. 2. Connect to Stable Wi-Fi An eSIM usually needs a stable internet connection during installation. Airport Wi-Fi, hotel Wi-Fi or another phone’s hotspot can work, but the connection needs to stay active. If you are using public Wi-Fi, check whether there is a login page. Some airport, hotel and plane Wi-Fi networks will not provide full internet access until you accept the terms or complete sign-in. And if installation froze halfway through: 3. Turn the eSIM Line Off and Back On An installed eSIM can sometimes fail to refresh properly. Open the travel eSIM line in settings, turn it off, wait around 10 seconds, then turn it back on. On iPhone, this may appear as Turn On This Line.On Android, this may appear as a SIM toggle. Label the line clearly, such as “TravelKon” or “Travel Data”, so it is not confused with the home SIM. 4. Set Mobile Data to the Travel eSIM This is one of the most common missed steps. Go to mobile data settings and choose

Losing access to a mobile number while overseas can turn a normal travel problem into a very stressful one. For anyone using travel eSIMs, it helps to know what SIM swap fraud is, what it is not, and how it differs from a standard eSIM setup issue.  Fortunately, most activation errors you encounter on the road are simply due to misconfigured settings or poor local network coverage. True SIM swapping requires malicious intent and identity theft, making it a completely different beast than a stubborn data plan.  Quick Answer A data-only eSIM for travel does not usually transfer your regular mobile number or replace your home SIM. SIM swap fraud travel concerns are mainly about protecting your normal mobile number while you are away. If your Australian number suddenly loses service, stops receiving SMS codes, or your carrier alerts you to a SIM change you did not request, contact your home mobile provider immediately. With the Australian Communications and Media Authority (ACMA) estimating that victims of mobile fraud and SIM swap scams lose an average of $28,000, acting fast is critical. But if your travel eSIM is not connecting, start with eSIM troubleshooting: mobile data settings, roaming settings, device compatibility, and the product instructions. What This Means for Overseas Travellers For most travellers, the practical risk is confusion. You may land overseas, turn on your phone, and see no data. That can feel alarming, particularly if you need maps, rideshare, banking, hotel details, or airport arrival messages. But no data on a travel eSIM does not automatically mean your number has been compromised. A data-only eSIM is generally designed to provide mobile data in your destination. And as earlier mentioned, your regular SIM remains linked to your usual mobile number unless your mobile provider makes a change to that number or SIM profile. While it requires malicious intent, data from identity support service IDCARE shows a massive 240% surge in people seeking help for phone porting and SIM swap fraud. Alarmingly, their data reveals that 90% of these cases happen silently without any direct engagement or interaction from the victim. The criminals rely entirely on leaked personal data bought online, which is why securing your carrier account before flying is so important. And that is why proper eSIM setup is required. Your phone may have two lines active: one for your regular number and one for your international eSIM. The goal is usually to use the travel eSIM for mobile data while keeping your home SIM available only if you need calls or SMS. For extra background before setup, our guide on how an eSIM works explains the basics and is a good starting point for everyone new to travel eSIMs. SIM Swap Fraud Travel Checklist 1. Before Departure Secure your mobile provider account before you leave. Use a strong password, add a PIN if your provider allows it, and turn on any extra account protection available. Move important accounts away from SMS-only verification where possible. Banking, email, cloud storage, and travel accounts are safer when protected with an authenticator app or other stronger login method. Check that your phone is unlocked and supports eSIM. A carrier-locked phone may not work with an international eSIM, even if the eSIM itself is valid. Save your eSIM installation email, QR code, order details, and instructions somewhere accessible offline. Screenshots can be helpful if Wi-Fi is unreliable later. 2. During eSIM Setup Install your eSIM using stable Wi-Fi. A hotel, home connection, or reliable airport Wi-Fi is better than trying to complete setup while rushing between gates. And as always, label the eSIM clearly in your device settings. Names such as “TravelKon Europe” or “Japan Data” make it easier to select the correct line for mobile data. Check whether roaming needs to be enabled for the travel eSIM. Some travel eSIM products require data roaming to connect to partner networks overseas. 3. On Airport Arrival Set mobile data to the travel eSIM. Keep your Australian SIM switched on only if you need your normal number for calls or SMS. Turn off data roaming on your home SIM if you are trying to avoid roaming charges. This helps prevent your phone from accidentally using your Australian provider for mobile data. Give the eSIM a few minutes to register on the local network. If it still does not connect, check the product instructions before changing multiple settings. If hotspot use matters, confirm that your device and eSIM plan support it. Hotspot behaviour can vary by product, phone model, and local network. 4. If Something Feels Wrong If your travel eSIM has no mobile data, treat it as a setup issue first. If your normal mobile number suddenly stops working, treat it as a possible carrier account issue and contact your home provider straight away. That split is important because we can only help with TravelKon eSIM setup and connectivity issues. Your home mobile provider is the right contact if your regular number appears to have been moved, blocked, or changed without permission. What Not to Do When Using an eSIM for Travel Try not to delete your eSIM too early. Reinstalling may not be possible, and rescanning the same QR code may not work. Do not rescan the QR code repeatedly without checking the instructions. If activation has already started, repeated attempts can make troubleshooting harder. You shouldn’t ignore carrier-lock warnings. If your phone is locked to a network, an eSIM from another provider may not work. Never assume emergency calls work the same way in every country. Emergency service access can vary by destination, device, network, and service type. Don’t leave your home SIM using mobile data if your goal is to avoid roaming charges. The common setup is a travel eSIM for data, a home SIM for SMS or calls only if needed. Do not assume a travel eSIM issue means SIM swap fraud. No signal, no data, or slow connection can come from settings, coverage, product activation timing, or device compatibility.

When your mobile data fails to load overseas, it is easy to think the eSIM has a problem. In many cases, the fix is much simpler. Your phone may just need the right APN, mobile data, or roaming settings. For international travellers who often use travel eSIMs, this is one of those setup checks worth knowing before departure, not while standing at the airport arrival trying to book a ride. APN settings eSIM issues can sound technical, but the steps are usually straightforward, as you are about to find out. Quick Answer An APN, or Access Point Name, is the setting your phone uses to connect to mobile data through a mobile network. With an eSIM, the APN may be added automatically during installation, or it may need to be entered manually. To update your APN, go to your phone’s mobile data settings, select the eSIM line, find the APN or Mobile Data Network section, and enter the APN shown in your eSIM instructions. The wording varies between iPhone and Android devices, so the exact menu name may look slightly different. Never try to guess the APN or delete the eSIM unless support tells you to. What This Means for Travellers A travel eSIM is usually used to access mobile data while overseas. Many plans are data-only, which means they are made for internet access rather than standard calls or SMS. This is important because your phone may show signal bars but still fail to load maps, WhatsApp, email, or browser pages. The signal bar only shows that the phone can utilise the available network. However, it does not always mean the mobile data settings are correct. For a data-only eSIM, the most common setup checks are simple: the eSIM must be installed, selected for mobile data, allowed to use roaming where required, and set with the correct APN if the product instructions provide one. If you are still getting familiar with eSIM setup, you may find it useful to go through our blog on how an eSIM works before tweaking device settings. APN Settings eSIM Checklist Use this checklist before making major changes. Check that the eSIM Is Installed Open your SIM or mobile service settings and confirm the eSIM appears on your device. If it is not visible, go back to your installation email and product instructions before trying to scan the QR code again. Select the eSIM for Mobile Data Make sure your international eSIM is selected as the line for mobile data. If your Australian SIM is still selected, your phone may try to use your home provider instead. Check Roaming Settings Carefully Many travel eSIM products need data roaming switched on for the eSIM line. The important part is making sure roaming is enabled for the travel eSIM, not accidentally for your home SIM. Switching roaming on for your Australian SIM may lead to extra charges depending on your home plan. Check the APN Field Find the APN or Mobile Data Network section. On some phones, this may sit under Cellular, Mobile Service, Mobile Network, Access Point Names, or Mobile Data Network. If your TravelKon product instructions provide a specific APN, enter it exactly as written. Even a small spelling mistake can stop mobile data from working. Turn Wi-Fi Off When Testing This is an easy one to miss. If your phone is connected to a hotel, cafe, or airport Wi-Fi, it may look like the eSIM is working when it is not. Turn Wi-Fi off briefly and test mobile data directly. Restart Your Phone After changing APN or roaming settings, restart the phone. This gives the device a clean chance to reconnect to the local network. Try Manual Network Selection If automatic network selection does not connect, try selecting a local network manually. Only choose networks listed or supported in your product instructions where that information is provided. Check Hotspot Separately If mobile data works but hotspot does not, the issue may be separate from the APN. Hotspot availability can depend on the eSIM plan, device, and network. Check the product details before changing unrelated settings. What Not to Do When Using a Travel eSIM Never delete the eSIM too early. Some eSIMs cannot be reinstalled after deletion, even if the QR code is still available. Do not rescan the QR code over and over unless the instructions or support team tell you to. If the eSIM is already installed, the problem is often in the settings rather than the QR code. Also, do not switch roaming on for your home SIM unless you understand the charges. For most travellers, the safer approach is to use the travel eSIM for mobile data and keep the home SIM controlled carefully. Try not to ignore carrier-lock warnings. If your phone is locked to a mobile provider, a travel eSIM may not work until the device is unlocked. Do not assume emergency calls, SMS, or phone numbers work the same way with every travel eSIM. Many travel eSIMs are data-only. Keep a backup option for urgent contact, especially when arriving late, travelling alone, or relying on mobile data for transport. Lastly, don’t keep changing random settings. Once the basic checks are done, contacting support is usually the next best step. How TravelKon Users Should Prepare Before departure, save your TravelKon installation email somewhere easy to access offline. Screenshots are useful, especially if airport Wi-Fi is slow or unreliable. Check your device compatibility before buying or installing. Make sure your phone supports eSIM and is not carrier-locked. Compatibility can vary by model and region, so it is worth checking the exact device rather than relying on the phone name alone. Install the eSIM on stable Wi-Fi, unless your product instructions say otherwise. Some plans may activate on installation, while others activate when they connect overseas, so the specific product instructions matter. Keep the destination, product instructions, and order details handy. If you need our support, this information helps avoid back-and-forth and makes troubleshooting faster. When to Contact

How do you set up an eSIM hotspot when travelling overseas? This is a practical question, particularly when a laptop needs internet at the airport, hotel Wi-Fi is unreliable, or a tablet needs mobile data on the move. For any traveller using a travel eSIM, hotspot sharing can be one of the most useful ways to stay connected. A smooth eSIM hotspot setup comes down to the right device settings, a compatible eSIM product, and a quick check before departure, so there are no surprises after landing. Quick Answer You can use a hotspot with a travel eSIM by following these four direct steps: Note: If your connected devices have no internet access after following these steps, you may need to manually update the APN (Access Point Name) settings in your eSIM configuration. However, keep in mind that hotspot support can depend on your device, destination, eSIM product, and local network. Before relying on it for work, study, maps, or family sharing, check the product instructions and confirm your device supports hotspot sharing with an eSIM. What an eSIM Hotspot Means An eSIM hotspot means your phone shares its mobile data connection with another device. Your phone connects to the overseas mobile network through the eSIM, then your laptop, tablet, or second phone connects to your phone by Wi-Fi, Bluetooth, or USB. In a nutshell, the eSIM provides the mobile data and hotspot passes that data along. This is helpful when public Wi-Fi is slow, unavailable, or not ideal for everyday travel tasks. It can support emails, browsing, maps, messaging, document uploads, and light work on a laptop. A travel eSIM is often data-only. That means it may not include standard calls or SMS, but that does not automatically stop hotspot use. The key is making sure the eSIM is connected to mobile data first. eSIM Hotspot Setup Checklist Use this checklist before departure or once you arrive overseas. Common Mistakes to Avoid Do not assume the eSIM is being used for data just because it is installed. Always check which SIM is selected for mobile data. Never turn off roaming for the travel eSIM unless the instructions say to. With many travel eSIMs, roaming settings are part of how the eSIM connects overseas. Thirdly, don’t delete the eSIM if it does not connect straight away. Some eSIMs may not be reusable after removal, and deleting it can make troubleshooting harder. Restart the phone, check the selected data line, review the instructions, and test again first. Do not expect hotspot speeds to be identical everywhere. Performance can change based on local network coverage, signal strength, network congestion, battery mode, and how many devices are connected. Last but not least, never leave hotspot running all day if it is not needed because it can drain your phone quickly, especially when a laptop is connected. TravelKon Connectivity Tips Before Departure Before travelling, check the TravelKon product details for your destination and confirm whether hotspot use is supported for the eSIM you selected. Save your setup instructions somewhere offline, such as in your files, photos, or email app. Install the eSIM before departure where possible, but follow the activation timing in the product instructions. Some eSIMs should only be activated close to travel or after arrival. You can also have a look at our blog on how an eSIM works to familiarise yourself with everything before travelling. The guide makes the setup process easier to understand and helps avoid confusion between your home SIM and your travel eSIM. When to Contact TravelKon Support Reach out to us if your eSIM is installed but mobile data will not connect, the hotspot option is missing, your device settings do not match the instructions, or hotspot is not working after mobile data is confirmed. Before contacting support, collect the details that will make troubleshooting faster. Helpful screenshots include your eSIM mobile data settings, roaming settings, APN settings if relevant, and any error messages. Also note your destination country, device model, eSIM product, and whether mobile data works on the phone before hotspot is turned on. That final detail is important. If mobile data does not work on the phone itself, the issue is likely with the eSIM connection rather than hotspot sharing. Final Thoughts A good eSIM hotspot setup starts before departure. Install the eSIM, check compatibility, save the instructions, set mobile data to the correct eSIM, confirm roaming settings, and test mobile data before switching on hotspot. Once your phone is online, sharing data is usually easy. The safest next step is to check the TravelKon eSIM instructions for your destination, then test the connection early so any settings can be fixed before you truly need it. FAQs Can You Use Hotspot With a Travel eSIM? Usually, yes, if the eSIM product, device, and destination network support it. Always check the product instructions before travelling if hotspot is important for work, study, or sharing data with another device. Can You Hotspot From a Data-Only eSIM? Often, yes. A data-only eSIM can still share mobile data by hotspot when hotspot is supported. Calls and SMS are separate features, so a data-only plan may still work for internet sharing even if it does not include standard phone services. Why Is My eSIM Hotspot Setup Not Working? The most common causes are the wrong SIM being selected for mobile data, roaming being switched off for the travel eSIM, a weak local network signal, incorrect APN settings, or hotspot not being supported for that specific eSIM product or device. Does Hotspot Use More Data? Hotspot itself does not automatically use more data, but connected devices often do. Laptops may run software updates, sync files, load desktop websites, and stream higher-quality video, which can use data much faster than normal phone browsing. Should Data Roaming Be On or Off? For the travel eSIM, data roaming may need to be on. For your home SIM, it is usually safer to keep roaming off unless you intentionally want to use it.

A strange mobile warning overseas can make anyone nervous. Besides, when your phone is your map, wallet, booking folder, translator, and ride home from the airport, you have no option but to always be careful how you use it. Most international travellers prefer using travel eSIMs as a practical way to get mobile data overseas without swapping physical SIM cards. Still, it helps to know what is normal, what needs attention, and what steps to take if something does not look right, especially with newer threats like getting your eSIM hacked. Quick Answer Yes, an eSIM can be hacked in theory, but in most travel situations, the bigger risk is not the eSIM itself being directly hacked. More common issues include scam links, phishing messages, unsafe public Wi-Fi, weak passwords, suspicious apps, a compromised device, or someone getting access to your eSIM QR code or account details. For example, cybersecurity data from the US Cybersecurity and Infrastructure Security Agency (CISA) via Zensec reveals that over 90% of all cyberattacks begin with a phishing attempt rather than direct hardware or software hacking. For travellers, the safest approach is to treat your eSIM details like private travel documents. Only use the instructions from your provider, keep your phone secure, avoid suspicious links, and contact support before deleting or reinstalling the eSIM. What This Means For Travellers A travel eSIM is usually used for mobile data while overseas. Many travel plans are data-only, which means they are designed for internet access rather than normal calls and SMS. That matters because some issues can look like security problems when they are actually eSIM setup issues. For example, your phone might still be using your home SIM for data, roaming might be off for the eSIM line, or the destination network may take a few minutes to connect after airport arrival. It is also worth knowing the basics of how an eSIM works before travelling. A little context makes eSIM troubleshooting much easier when you are tired, in a queue, or trying to connect straight after landing. Step-By-Step Safety And Troubleshooting Checklist What Not To Do When Using TravelKon eSIMs You shouldn’t delete the eSIM as your first troubleshooting step. Once removed, it may not be simple to reinstall, depending on the plan and provider. Avoid rescanning the QR code unless the instructions say this is allowed. If the QR code has already been used or was installed on the wrong device, contact support before trying again. Never ignore carrier-lock messages. If the phone is locked, the eSIM may not work until the lock issue is resolved with your carrier. Do not assume a data-only eSIM will handle calls, SMS, or emergency access the same way your home SIM does. These functions can vary by device, carrier, country, and plan type. Ensure you don’t leave your home SIM’s international roaming on without checking the settings. It may be useful for SMS or calls, but it can also create unexpected charges if mobile data uses the wrong line. How TravelKon Users Should Prepare If you’re using our travel eSIMs, we recommend that you prepare before departure rather than waiting until the plane lands. Start by checking the product page for your destination, data allowance, validity period, hotspot notes, installation timing, and any plan-specific instructions. Then confirm your phone supports eSIM and is unlocked. Also, save your TravelKon installation email before you leave. Keep the QR code, manual setup details, order number, and instructions handy. Installing while connected to Wi-Fi is usually the easiest option, especially if the product allows installation before travel. Before departure, check which SIM is set for mobile data, which SIM is used for calls and messages, and whether your home SIM’s roaming is switched off or controlled properly. After arriving at the airport, turn on the TravelKon eSIM, select it as the mobile data, follow the product instructions for roaming, and give the phone a few minutes to connect. If it does not work, avoid changing too many settings at once. Work through the instructions first, then contact TravelKon support if you are still stuck. When To Contact TravelKon Support Contact support if your eSIM has been installed but will not connect after following the instructions, the QR code says it has already been used, your phone shows a carrier-lock warning, your destination network does not appear, data is being used from the wrong SIM, or you are unsure whether deleting the eSIM is safe. Include your device model, destination, order details, plan name, screenshots of the issue, and a short note explaining what has already been tried. That makes eSIM troubleshooting faster and avoids repeated back-and-forth. Final Thoughts Most eSIM issues come from setup confusion, unsafe links, exposed details, device problems, or the wrong SIM being used for mobile data. The safest move is to choose the right international eSIM, check compatibility, save the setup instructions, install on Wi-Fi where possible, and avoid deleting or rescanning anything unless the instructions or support team advise it. For TravelKon users, a few checks before departure can make staying connected overseas much easier. FAQs Can an eSIM Be Hacked? Yes, an eSIM can be hacked in theory, but most travel-related concerns are more likely to involve phishing, unsafe links, exposed account details, suspicious apps, or incorrect setup. Keep your eSIM QR code private and only follow the official installation instructions. What Should I Do If I Think My eSIM Was Hacked? Stop using suspicious links, turn off mobile data temporarily if needed, check for unknown apps or profiles, update your phone, and change important passwords using a trusted connection. If the issue relates to your eSIM setup, contact support before deleting or reinstalling anything. Is A Travel eSIM Safer Than Public Wi-Fi? A travel eSIM can reduce your need for unknown public Wi-Fi, which is helpful overseas. It does not remove every online risk, so still be careful with passwords, payment pages, banking apps, and unexpected messages. Can Someone Else Use My eSIM

When travelling overseas, mobile connection is not just about maps, messages, and airport transfers. It is also about feeling confident that help is still reachable if something goes wrong. That is why eSIM emergency calls are such a common concern for most travellers. A travel eSIM can be a simple way to stay connected overseas, but it is important to understand what type of service it provides before relying on it in a serious situation.  Quick Answer Emergency calling depends on your phone, destination, available mobile networks, local emergency services, and whether your device can connect to a suitable network at the time. A data-only eSIM is mainly designed for mobile data. It usually does not include a standard phone number, regular voice calls, or SMS. Emergency calling is not an eSIM feature that should be treated as guaranteed. It is generally handled at the device and network level, and conditions can vary by country and carrier. In practical terms, your travel eSIM can still be very useful in an emergency because mobile data can help you use maps, messaging apps, browser search, rideshare apps, translation tools, and location sharing. But it should not be your only emergency plan. What This Means for Travellers For most travellers, an international eSIM is best understood as a mobile data connection. It helps you get online after airport arrival, use your travel apps, message family, find your hotel, and avoid relying only on public Wi-Fi. That data can come in handy in urgent situations. With working mobile data, you may be able to message someone for help, share your live location, search for nearby medical care, contact your accommodation, or use internet-based calling apps such as WhatsApp, Messenger, or FaceTime. This is different from making a normal phone call through a mobile number. If your eSIM is data-only, it should not be treated as a full replacement for your home SIM. If your phone supports dual SIM, you may choose to keep your Australian SIM or primary line available for calls and SMS while using the travel eSIM for data. Just check your home provider’s roaming fees first, especially for calls, texts, and data roaming. Take your time and go through our guide on how an eSIM works before travelling. Step-by-Step Checklist Before You Travel What Not to Do When Travelling Do not assume “SOS”, “Emergency Calls Only”, “No Service”, and “No Internet” all mean the same thing. These messages can point to different issues. Never rely only on one connection method. Keep offline maps, hotel details, travel insurance contacts, embassy details, and a backup way to contact someone. Don’t assume emergency calls work the same way everywhere. Emergency numbers, network behaviour, location handling, and service availability can vary by country. How TravelKon Users Should Prepare Our eSIM users should start with the product page and installation email for the exact eSIM purchased. That is where the most relevant setup details should be checked, including destination coverage, data allowance, activation timing, roaming settings, and any plan-specific notes. Before departure, confirm that your device supports eSIM and is unlocked. Install the eSIM on reliable Wi-Fi, then label the line clearly in your phone settings.  If hotspot is important, check the product details before relying on it. Hotspot availability can depend on the plan, destination, network, and device settings. It is also worth saving the installation email somewhere easy to access offline. If you need support, having screenshots and order details ready will make the process much faster. When to Contact TravelKon Support Contact our support team rather than guessing if the eSIM is installed but mobile data does not work after arrival, the eSIM profile is missing from your settings, your device shows a carrier-lock warning, the QR code will not scan, the plan appears active but no network connects, or you are unsure whether deleting the eSIM will cause issues. When asking for help, include your order details, destination, device model, screenshots of your mobile data settings, any error messages, and the steps already tried. Final Thoughts The safest way to think about eSIM emergency calls is that a travel eSIM can help you stay connected through mobile data, but it should not be treated as a guaranteed emergency calling service. Before departure, check your plan instructions, save local emergency numbers, keep a backup contact method where possible, and avoid deleting the eSIM if setup does not work straight away. If something looks wrong, contact our team with your order details, device model, destination, and screenshots so the issue can be checked properly. FAQs Can a Data-Only eSIM Make Emergency Calls? A data only eSIM usually does not include standard voice calls or SMS. Emergency calling may still be possible in some situations through the phone and available local networks, but this depends on the country, carrier, device, and emergency number. It should not be treated as guaranteed. Will Emergency Calls Use My TravelKon eSIM Data? Emergency calls are not the same as using mobile data through a TravelKon eSIM. A data-only eSIM helps with internet access, apps, maps, messages, and online tools. Emergency calling is generally handled by the phone and available mobile networks, not as a normal data feature of the travel eSIM. Why Does My Phone Say “Emergency Calls Only”? This usually means your phone is not connected to a normal mobile service for that line, but it may still detect a network for emergency access. Check that the eSIM is turned on, the travel eSIM is selected for mobile data, data roaming is enabled if required, and the destination is included in your plan. Should I Delete My eSIM if It Is Not Working? No. Do not delete it unless the setup instructions or support team tells you to. Deleting an eSIM may stop you from reinstalling it and can make troubleshooting harder. Can I Use WhatsApp With a Travel eSIM? Usually, yes, as long as the travel eSIM has working mobile data. Apps such as WhatsApp, Messenger,
