Reviews
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
good connection
Without doubt this eSIM has been working faultlessly on 4 and 5G
Its absolutely a good desision that i purchased an esim at travelkon its hassle free as soon i arrived in Japan it activate straight away. I’ll used it again in my next asia adventure. Thanks
I bought 3 eSIM for Japan trip, it’s super easy to set up and use it, just activate and switch on and off the phone then it came effective
Tested in Japan, works great! Set up instructions are easy to follow.
Easy to use and WIFI connection seems fine as we were travelling across main island & north island.
Easy to set up and assistance was extremely prompt and clear. Will purchase again for sure.
Used in Japan and no issues at all
Easy to activate, did this at home before leaving. Then easy to switch on with 2 settings changes after we landed whilst still on the plane!
