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

Easy to use!

I made the decision to switch from Mint Mobile and Visible Wireless due to sever deprioritization issues. I made the decision to go with T Mobile prepaid. I stumbled across this app and couldn’t believe how easy it was to set up on my iPhone 12 Pro.

The only “issue” I had was that I didn’t see any option in the app to port my number from my previous carrier (It assigned me a new number), but I made a phone call to T Mobile prepaid and it was ported instantly! It took maybe 5 minutes, in total, on the phone (make sure you have your account number and pin from your previous carrier). Very minor inconvenience, but if that option was added to the app, it would make this app PERFECT.

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.
