This is BIG

Since I use T and Metro sims while visiting US, I always struggle - go to store, buy a SIM card, extra expenses, no refill for Metro, system do not accept non US cards... This app makes my life much easier - thanks

Only improvement you can do is to add a week or two plans for tourists who do not stay for a month and just visit for short period of time

1. Not all of T-Mobile Prepaid plans are available.
2. You cannot port your number from another carrier. You have to settle for whatever number they assign you.
3. You cannot use an email address that you have used in the past with T-Mobile.
4. It isn’t clear what to do after you complete the purchase. Is the app good for anything else? Can you uninstall it? No clear idea.
5. Accessibility for blind users is unusable. All pages of the app are presented to VoiceOver... all at once. You may end up way back in the sign up process, or way ahead, with no assistance as to return to the correct spot. It’s awful.

To ppl bought their device in CHINA

To ppl bought their device in CHINA, DO NOT DOWNLOAD THIS APP!! It will say device not compatible with this app and cannot use eSIM on this device. Chinese iPhone does not support eSIM and this app will not work as normal.

The app is good and easy to purchase a plan on the phone. No need too many steps. Good.
