FAQs

 

What do I need to do to use the eSIM with T-Mobile?

Getting started is easy. You’ll first need an iPhone XS, XS Max, or XR with iOS 12.1.1 or later purchased from T-Mobile or unlocked if purchased from another retailer. Then download the T-Mobile eSIM app from the App Store. Enter an email address to create your new T-Mobile prepaid account and then follow the activation steps to select your plan. Current T-Mobile customers will have to enter a new email address if it’s already connected to a T-Mobile account.

What plans are available for T-Mobile eSIM activation?

T-Mobile offers three prepaid plans for eSIM activation. They are:

  • T-Mobile ONE Prepaid with unlimited voice, text, and data for $70; 30 day expiry with renewal option
  • Simply Prepaid with unlimited voice, text, and 10GB of LTE data for $40; 30 day expiry with renewal option
  • Tourist Plan with 1000 minutes, unlimited text, and 2GB of LTE data for $30; 21 day expiry

 

Do I need to pay any fees to activate eSIM with T-Mobile?

At this time there are no fees to activate eSIM with T-Mobile.

 

Can I activate eSIM as a standalone account at T-Mobile?

Yes. If you already have an iPhone from another provider and want to activate a prepaid line, you can activate eSIM as your standalone T-Mobile account. However, if your iPhone is locked to another service provider, you will need to unlock it before you can activate a T-Mobile eSIM.

 

Why are you choosing to support eSIM with an app?

T-Mobile is making it simple to light up eSIM. Just download the app and select a prepaid plan that works for you. No trekking to a store or juggling two different physical SIM cards – adding a line is done from the convenience of the app, wherever you are. The eSIM app was built for travelers coming to the U.S., existing T-Mobile customers who want a secondary pre-paid line and anyone who wants to take the Un-carrier out for a test drive to try out America’s fastest 4G LTE network.
