Should you buy your Ubigi eSIM data plan before traveling, or when you arrive?
Either is possible! You can purchase your Ubigi data plan right before you leave or when you arrive at your destination, whichever is most convenient for you. Thanks to the SmartStart feature, the validity period of your data plan starts automatically upon arrival in a covered area, ensuring you do not lose any days before your travel.
Getting started with SmartStart is easy! 🚀 Upon arrival, simply switch on your Ubigi line in your mobile settings—your data plan will activate automatically, and its validity will begin.
If you have not purchased a plan before leaving, you can buy your data plan when you arrive at your destination and it will activate immediately. Good to know: Even after you have used up all your data allowance or you have no Wi-Fi, you can still recharge from the UBIGI app anywhere in the world and check data usage.
Note: We recommend installing your Ubigi eSIM on your device before you travel. Internet connectivity is required to download the eSIM profile on your device. (For Android users, you can only install new eSIM profiles while connected to Wi-Fi).

Family able to help with first time use of esim
My daughter was able to set up the account for esim on my mobile. Started using it at London Heathrow Airport to make sure no problems so my son could tell me how to change the settings to activate the esim. It worked everywhere I went in the Caribbean and I was able to send photos to family in UK.

Works great
Works great. Even in seemingly remote locations that I thought there would be no coverage. I will definitely use this eSIM carrier next time I’m out of my home carrier coverage

Promotion code
The app was easy to use but I got a login issue with discount code through manual. It was a bit hard to find how to put the promotion code "NTT20" with NTT account

Japan on Samsung's S24 Ultra
On Samsung's S24 this app installed the esim easily. The data was activated when we got to Japan, not before. The coverage has been good so far. I did have to update the access point name on the esim, that didn't auto select, but maybe a side effect of having other esims previously.

What made my experience good was being able to commit majority of the time
What made my experience good was being able to communicate with loved ones majorly of the time.
It so great- network was better not as I expected because there were times when Ubigi was not able to connect to internet.
Generally, it was a better experience.
