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

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.

Security concerns!!!!!!

It’s a great idea and I have been excited about eSIM for months waiting for my carrier to unlock my phone after the 90 day period. T-Mobile was innovative by releasing this app but their US operations have no commitment to security. Their customer support is terrible and they’ve been suspicious and dishonest toward me. I am 99% sure they compromised my phones security or at the very least deliberately altered setting on my line and went against my wishes. I noticed that Telekom Deutsche has much higher standards than US operations. And I am an investor and they did this to me so imagine the average customer.
