T-Mobile Prepaid eSIM app

T-Mobile eSIM is an app that lets Apple iPhones with dual SIM support activate new T-Mobile prepaid service.

 

No trekking to a store or juggling two different physical SIM cards – adding a line is done from the app, wherever you are.

 

 

 

About the app

The eSIM app was built for travelers coming to the U.S., existing T-Mobile customers who want a secondary prepaid line, and anyone who wants to take the Un-carrier out for a test drive to try out America’s fastest 4G LTE network.

 

  • The app can only activate a T-Mobile prepaid line.
  • For postpaid accounts, check out T-Mobile eSIM.
  • Only available for Apple iPhone XS, iPhone XS Max, iPhone XR, iPhone 11, iPhone 11 Pro and iPhone Pro Max running iOS 12.1.1 or later.

  • The app requires:
    • You have a data connection, through either Wi-Fi or Cellular.
    • You either purchased the iPhone from T-Mobile, or else you must first SIM unlock it. (Contact the original provider if you need help.)
  • There are no fees to activate an iPhone with an eSIM.
  • To activate your iPhone eSIM on another wireless provider or manage eSIM settings, see eSIM settings: Apple iPhone on iOS 13.

Re-download eSIM after replacing device or master reset

Sometimes, you may need to replace the eSIM you received through the app.

 

  • You accidentally deleted your eSIM.
  • You upgraded your phone, and want to transfer your eSIM line of service to your new phone.
  • You lost connection when downloading your eSIM, and it didn't get installed properly on your device.

 

To start, you'll need to call us at 1-877-778-2106 to get a QR code. Make sure you have:

 

  • Your Prepaid eSIM phone number or your OrderID. Your OrderID will display if you encounter an error screen in the T-Mobile eSIM App.
  • Your account PIN code, which you set up to complete your order in the T-Mobile eSIM App.
