Nobody wants their holiday vibes ruined by mobile data anxiety. You want to land, hail a ride or tell a loved one you’ve arrived safely; it should just work. However, it’s never that easy, given the number of travel eSIM options available to choose from.
To make things easier, we’re going to compare TravelKon and Optus Roaming, both of which are designed to keep you connected overseas. Optus leans hard into simplicity for its postpaid crowd. For A$5 every 24 hours in Zone 1 destinations, you keep your Aussie number active and just go.
At TravelKone, we’ve always believed travel is better when your tech is actually tailored to the destination. As such, we offer destination-specific eSIMs and travel SIMs designed to help travellers avoid the day-by-day roaming model altogether. For travellers also comparing eSIM vs data roaming, that difference is a big part of the decision.
Quick Answer
Choose Optus Roaming if convenience is your top priority. On eligible postpaid plans, Optus Daily Roaming is A$5 per 24 hours in 150+ Zone 1 destinations and includes 5GB plus unlimited standard talk and text, with another 5GB added for another $5 if you keep using the service.
Go for TravelKon if you want to avoid paying by the day, choose a destination-specific setup before departure, and buy a product that feels more closely matched to the trip itself. Our current products are especially strong for Europe, Japan, Bali, Indonesia, and Asia regional travel.
That is part of what makes TravelKon so appealing for readers planning a real holiday rather than just looking for the most familiar option. The range feels built around where people are actually going. Europe has a standout 3UK option with local calls and texts. Japan has more than one product family, Bali has a dedicated Bali path, and Asia regional gives travellers a clear split between fixed-data and unlimited-style options.
Note: We are only covering postpaid Optus products because the prepaid roaming option is different. The current prepaid page lists a A$5 one-day option with 1GB, 50 SMS, and up to 25 minutes, plus larger prepaid roaming packs.
TravelKon vs Optus Roaming: The Honest Breakdown
| Feature | TravelKon | Optus Roaming | Why it matters |
|---|---|---|---|
How it works | Buy a travel eSIM or SIM for the destination | Use your existing Optus service overseas | TravelKon is more trip-specific. Optus is more plug-and-play. |
Cost model | Upfront trip-based pricing | A$5 per 24 hours on eligible postpaid plans | TravelKon is easier to budget before you fly. Optus charges stack up day by day. |
Phone number | Usually data-first, but selected plans include a number | You keep your Australian number | Optus is easier if keeping your usual number is the main priority. |
Included usage | Depends on the plan you buy | 5GB plus unlimited standard talk and text per 24 hours on eligible plans | Optus is very convenient, but only while the daily roaming fee keeps running. |
Extra data | Buy another eSIM if needed | Another 5GB for another A$5 if you keep using the service | Optus is easier mid-trip, but the cost can keep growing. |
Buy-ahead flexibility | Many TravelKon products can be bought well ahead of departure | Activates automatically on first eligible use overseas if roaming is enabled | TravelKon suits organised travellers. Optus suits travellers who want to think less about setup. |
Best for | Travellers who want cost control and destination-led choice | Travellers who want maximum convenience with their existing number | It comes down to travel-first value versus roaming-first convenience. |

Why TravelKon Stands Out
Optus Daily Roaming is clearly convenient. On eligible postpaid plans, it is auto-turned on, activates when you first use your service in an eligible destination if roaming is enabled in your device settings and My Optus, and gives 5GB plus unlimited standard talk and text for A$5 per 24 hours. If you keep using your service after that, an additional 5GB is added for A$5.
TravelKon works differently. Instead of paying every day your service is active overseas, you buy a product built for the destination or the route. That makes the decision feel more like trip planning and less like accepting a running meter in the background. TravelKon also allows you to buy many products ahead of time and keep the QR code until you are ready to use it.
And that is TravelKon’s real kicker. We give travellers a chance to sort out their setup before departure, choose something that actually fits the itinerary, and head off with a much clearer sense of what the trip will cost.
Optus roaming fees: How They really Add Up
Optus Daily Roaming can sound inexpensive because the daily fee is small. The problem is that most trips are not one day long.
For a 7-day trip, Optus Roaming costs A$35. For 14 days, it becomes A$70. For 21 days, it becomes A$105. For 30 days, it becomes A$150. If you use your 5GB inside the 24-hour window and keep going, Optus adds another 5GB for another A$5.
That is one of the clearest reasons TravelKon makes sense for many leisure travellers. It replaces the daily-fee mindset with a more straightforward travel product, which is often easier to justify before you even leave home.
| Trip length | Optus Daily Roaming | TravelKon example |
|---|---|---|
7 days | A$35 | Indonesia 10GB / 30 days A$18 |
14 days | A$70 | Japan 10GB / 30 days A$25 |
30 days | A$150 | Asia 13 Countries 10GB / 30 days A$35 |
Those TravelKon comparison prices come from our Indonesia, Japan Docomo IIJ, and Asia 13 Countries product pages.
Who TravelKon is Better For
- Travellers who want to avoid paying a daily roaming fee for every day overseas.
- Holidaymakers heading to Europe, Japan, Bali, Indonesia, or multiple countries in Asia.
- Travellers who prefer choosing a prepaid travel product before departure.
- People who mainly need strong data for maps, messaging apps, ride-share apps, and travel planning.
- Travellers who want destination-led options instead of one roaming model for every trip.
- Australian travellers who value local support channels.
That is really the shape of the TravelKon sweet spot. It works best for travellers who want their mobile setup to feel like part of the trip plan rather than an extension of their home service at daily roaming rates.
Europe: Where TravelKon Gives You a Stronger Travel Product
Europe is arguably where TravelKon flexes its muscles, particularly with our UK & Europe eSIM 71 Destinations | 3UK offering. You’re looking at A$27 for 40GB over 30 days, A$37 for 100GB, A$47 for 200GB, and A$77 for the Unlimited UK option. This includes a UK number, local calls and texts in the UK and Europe, hotspot support, 30 days of service, and can be used within 1 year.
You should, however, remember that we have a Go Roam cap when you leave the UK. The 40GB plan includes 6GB outside the UK in Go Roam countries, the 100GB plan includes 12GB, the 200GB plan includes 18GB, and the Unlimited UK plan includes 30GB outside the UK. Is it a dealbreaker? Hardly, but it’s a detail you’ll want in your back pocket before hitting the tarmac in Paris or Rome.
Even with that clarification, TravelKon still looks very strong on upfront value for longer Europe trips. Against Optus Daily Roaming at A$5 in eligible destinations, TravelKon feels much more like a product built for travel rather than a home plan carried overseas. For readers mapping out a bigger itinerary, it also fits naturally with planning a 1 month Europe trip from Australia.
Japan: Where TravelKon Looks Much Better In Terms of Value
Planning a Tokyo getaway? Let’s talk logistics. On Optus Daily Roaming’s current pricing, a 7-day Japan trip would cost A$35, a 14-day trip would cost A$70, and a 30-day trip would cost A$150, assuming Japan is one of your eligible Daily Roaming destinations. Optus’s own rates finder is still the right place to verify a specific country before travel, which is one reason this comparison is important for travellers already doing Japan trip planning.
TravelKon gives Japan travellers both better pricing and a more interesting product mix. The Japan eSIM | Docomo IIJ is A$9 for 3GB / 30 days, A$15 for 5GB / 30 days, A$25 for 10GB / 30 days, A$35 for 20GB / 30 days, and A$65 for 50GB / 30 days. It is data-only and usable within 180 days.
That means TravelKon’s 10GB Japan plan for a full 30 days costs less than Optus Daily Roaming for a single week. And beyond the price, TravelKon’s wider Japan range gives readers more than one way to buy for the trip, including broader category paths such as KDDI-based and Japan 5G products. That makes the TravelKon option feel better thought through, not just cheaper.
Bali: Where Destination-Led Buying Feels Much Easier
Bali is a good example of why every traveller should always consider destination-led shopping. Our Bali eSIM page clearly says TravelKon’s Bali eSIM tethers you to the Telkomsel network. It also highlights instant QR activation and mentions coverage across places such as Denpasar Airport, Seminyak, Canggu, Ubud, Kuta, and Uluwatu.
Optus can still get you online in Bali through eligible roaming, but the pricing logic stays the same: A$5 per 24 hours on eligible postpaid plans. For Bali-specific travel, TravelKon feels much more direct because you are buying a Bali-focused product instead of relying on a generic daily roaming model. That feels even more natural for travellers already planning a Bali itinerary rather than just searching for Indonesia in general.
Indonesia: Where TravelKon is Much Sharper On Price
Stepping off the plane in Denpasar usually triggers a frantic search for the skip button on roaming fees. If you’re on an Optus postpaid plan, the Daily Roaming costs A$35 for 7 days, A$70 for 14 days, and A$150 for 30 days on eligible postpaid plans.
TravelKon’s Indonesia eSIM is A$4 for 1GB / 7 days, A$8 for 3GB / 30 days, A$12 for 5GB / 30 days, A$18 for 10GB / 30 days, A$29 for 20GB / 30 days, and A$39 for 30GB / 30 days. Why pay for a premium daily rate when you can tap into Telkomsel and XL via 3HK the moment you land?
That makes Indonesia one of the easiest places to recommend TravelKon. Optus is more convenient if you absolutely want to keep your Australian number active. But on pure holiday value, TravelKon is hard to argue against here, especially for readers comparing the best eSIM for Indonesia before they buy.
Asia regional: Where TravelKon Makes More Sense for Longer Itineraries
Multi-country travel in Asia is where daily roaming charges can feel especially wasteful. A 14-day trip on Optus Daily Roaming costs A$70. A 30-day trip costs A$150.
TravelKon offers a clearer regional alternative. The Asia 5G eSIM 13 Countries is A$19 for 3GB / 30 days, A$25 for 5GB / 30 days, A$35 for 10GB / 30 days, A$45 for 20GB / 30 days, and A$55 for 30GB / 30 days. We provide data-only, 4G/5G, usable within 180 days, supports hotspot/tethering, has no daily limit, and continues at 128kbps after the main allowance.
If you want unlimited-style travel instead, we also offer that as a separate product path rather than lumping everything together. That clearer product structure is one of the reasons TravelKon fits real Asia itineraries so well, particularly for travellers also weighing eSIM, roaming, and local SIM options in Southeast Asia.
Calls, Texts, Your Number, and WhatsApp
Optus definitely takes the cake for pure convenience here. With Daily Roaming on eligible postpaid plans, you keep your current Australian number and get unlimited standard talk and text plus 5GB per 24 hours. Honestly, if your entire itinerary depends on clients or family reaching you on that same old number without missing a beat, that is a hard perk to overlook.
But what if you are burning through data on the go? TravelKon is more data-first across most of its range, although selected plans such as Europe 3UK include a number plus local calls and texts. Besides, you can still use your existing WhatsApp number with our travel SIMs and eSIMs, which is an important practical point for many leisure travellers.
For plenty of blog readers, that is the real trade-off in plain English. Optus wins on keeping the home-number experience unchanged. TravelKon wins when strong data, better value, and a more trip-specific setup matter more than using your Australian number exactly as usual.
Top-Ups, Support, and Buying Ahead
Optus’s clearest convenience edge is that you do not need to buy a separate travel product if your eligible plan already supports Daily Roaming. But outside those eligible setups or destinations, Optus says standard roaming rates can apply, which is why checking the rates finder before travel is important.
Sorting your connectivity shouldn’t feel like a last-minute scramble at the arrivals gate. While some services lean on mid-trip top-ups, TravelKon champions a choose-right, choose-once model. It’s built for the planner who wants everything locked in before the suitcase is even packed. Need a Japan or Asia plan? You’ve often got a massive 180-day window to activate. Heading to Europe? The 3UK eSIMs stay valid for a full year.
Sure, you won’t find a top-up button here, you simply grab a fresh eSIM if data runs thin, but isn’t peace of mind worth more? With 24/7 support via WhatsApp or Messenger, you’re never truly flying solo. It’s about that confidence: QR code ready, bags packed, and zero stress.
Final Verdict
Choosing Optus Roaming is essentially a set-and-forget move. Its greatest strength? Pure simplicity. You keep your number, use your current service overseas, and do not need to think too hard about setup. For work travel, last-minute trips, or travellers who absolutely need to stay on their Australian number, that can be enough to justify it.
But for many leisure travellers, TravelKon makes the stronger case. It gives you a clearer way to control costs, pick a plan around the destination, and avoid turning mobile data into a daily roaming expense. Our products are especially persuasive in Europe, Japan, Bali, Indonesia, and Asia regional travel, where the current product pages make the value story easy to understand.
It feels more like a travel product chosen for the journey ahead. For blog readers who want something consumer-friendly, easy to understand, and genuinely useful, it’s a robust choice without claiming to be the only way to travel.
FAQs
Is TravelKon cheaper than Optus Roaming?
In many common travel scenarios, yes. Optus Daily Roaming is A$5 per 24 hours on eligible postpaid plans, which becomes A$35 for a week, A$70 for two weeks, and A$150 for a month. TravelKon’s current examples are much lower in many destinations, such as Japan 10GB / 30 days at A$25, Indonesia 10GB / 30 days at A$18, and Asia 13 Countries 10GB / 30 days at A$35.
Is TravelKon better than Optus Roaming for Europe?
For many leisure travellers, yes. TravelKon’s Europe 3UK product combines a UK number, local calls and texts, hotspot support, and lower upfront pricing than paying A$5 per day over a longer trip. The main thing to understand is that roaming data outside the UK is capped by tier.
Does TravelKon still work if I mainly use WhatsApp?
Yes. TravelKon allows you to keep using your existing WhatsApp number with its travel SIMs and eSIMs, which is one of the main reasons many travellers do not feel the need to rely on roaming for everyday communication.
Is TravelKon better for Bali and Indonesia trips?
Often, yes. TravelKon has direct Bali and Indonesia paths, clearly names local network detail, and is much easier to justify on price than paying Optus’s daily roaming fee across the whole trip.
When does Optus Roaming make more sense?
Optus Roaming makes the most sense when keeping your Australian number active is the top priority and convenience matters more than the day-by-day cost.
What is the best reason to choose TravelKon over Optus Roaming?
The best reason is cost control with better trip fit. TravelKon lets you choose a destination-specific setup before you fly, which usually feels more practical for holidays than paying a daily roaming fee in the background.
