Adding the eSIM outside the coverage country may result in a “failed activation,” which is normal. The eSIM will activate once you reach your destination.
Turn off the eSIM line and do not turn on data roaming until you reach your destination.
Check network coverage in your intended travel areas; Coverage issues are outside our control and we do not offer refunds.
Fair Usage Policy – this eSIM includes unlimited data for the duration of its validity. However, the service provider reserves the right to apply a Fair Use Policy and limit your data speed for up to 24 hours to ensure optimal network performance.

Reviews

Excellent.

Easy to use, great price, SIM card worked really well all around Japan, however it would not work in my old Samsung A30 phone, which I didnt realize until I tried it. But it worked great in my A73.

Loved the Internet access

It was simple to use once I worked out how to remove my Oz sim. Customer support was there to assist too. Thank you

Great sim easy to connect and use.

Excellent service.

Seamless e-sim download and setup. Speed was reliable and consistent.

Great

Used in Japan, Worked very well!

Surprised at the coverage and value for money

Unlimited in japan no limits, amazing coverage everywhere I went. 5g everywhere
Absolutely recommend, and will use again next travel trip.

it worked beautifully

I configured the eSIM here in AU before going to Japan, then as soon as we landed, I disabled my AU SIM and enabled the eSIM, it didn't work :) because I forgot to enable "Roaming", once I did that, it worked PERFECTLY
I even bought an additional one during my trip and also worked.
Perfect service, whatsapp chat replied immediately to help

Great service

Great service, user friendly and easy to install

Life saver

We traveled to japan with some friends and decided to use our own telecomunications providers roaming service at first, but realised very quickly it was expensive. Our friends put me onto travelkon and couldnt believe the pricing. Both my wife and i jumped on the product and couldnt have been happier with it. Great coverage and quick download and upload rates so we were able to videocall back home with ease and send plenty of videos and snaps back. Thanks again TravelKon

Japan 30 day sim card

20% disc is very good chance to buy and very reliable and quick service. My past hassle-free experience with TravelKon sim card gives me more confident to buy more from the provider, both internet service received and purchasing experience.
