Thanks to the new SmartStart feature, your data plan activates automatically upon arrival in a covered area, starting its validity period. This ensures you can fully use it without losing any days before your travel.
Once purchased, your data plan appears in the “My Account” tab on your Ubigi account, where you can track data plan usage and renewal details.
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.
Note: If you are already in a covered area when you purchase the data plan, activation starts immediately.
What happens if I don’t activate my data plan right away?
If your data plan is not activated within six months of purchase, it will automatically expire and cannot be used. To avoid losing your plan, make sure to connect to activate your Ubigi eSIM within this period to activate and begin using your data plan.

Overall really great
Once I understood how to get everything set up it was great, I only had a handful of times where the reception wasn't amazing.

There are better eSims
Easy installation of the eSIM. The app was slow, never reported the correct usage, the iPhone widget never worked. Had issues with it not finding a network to connect too when I was in the middle of Bangkok, many times after phone was put into airplane mode then back to normal. Received a message that I was out of data on the second day when I knew was that was wrong. I used others eSIM providers and this is not one of the better ones.
