The SIM card or eSIM is your device's ticket to the T-Mobile network!

 

What's a SIM card / eSIM?

  • The SIM card is a physical chip that you insert in your phone. It’s tied to your phone number and identifies you, the subscriber, to the T-Mobile network.
  • Embedded SIM (eSIM) is just a physical SIM card gone digital. Like a SIM card, an eSIM provides your connection to the T-Mobile network.
  • Some devices can accommodate both an eSIM and a SIM card at the same time, so you can have two wireless accounts with talk, text, and data on one device.
  • This is great for having both work and personal phone numbers on the same device, or when you're traveling internationally!

T-Mobile SIM cards come with adapters, in case your device uses a nano, micro, or standard card.

 

Set up your eSIM

Download your eSIM on iPhone

As long as you connect to Wi-Fi, your iPhone will automatically prompt you to activate your eSIM during setup. If you're switching between Android & iPhone, or have an iPad or Apple Watch, you'll need to Activate your eSIM on T-Mobile.com.

 
New to T-Mobile
 
  • During the initial setup, choose New Cellular Plan > Continue. You won't have a network connection if you choose "Not now".
  • Didn't get a prompt or chose to activate later? You can activate your eSIM from the device settings.
 
Upgrade from another iPhone
 
  • During the initial setup, choose your phone number then select Continue. You won't have a network connection if you choose "Not now".
  • Didn't get a prompt or chose to activate later? You can transfer your eSIM from the device settings.

Download your eSIM on Samsung phones

Prepaid

T-Mobile Prepaid customers must install the T-Mobile Prepaid eSIM app on an eSIM-capable iPhone.

Activate eSIM on T-Mobile.com

For other devices, or if you're switching between Apple & Android, follow these steps:

  1. Make sure your device is connected to Wi-Fi before you begin. 
  2. Log into your T-Mobile Account to change your SIM using your device EID. To find your EID:
    • Apple: From the home screen, select Settings General About.
    • Android: From the list of apps, select Settings About Phone > SIM Status or Status Information.
    • T-Mobile For Business customers should use the Account Hub.
  3. Activate your eSIM if your device supports multiple eSIM profiles:
    • iPhone: Tap the notification to activate the eSIM on your device.
    • Android: Scan the QR code. Our Tutorials have steps for supported devices, like the Google Pixel 6 Pro, moto razr 5G, or Samsung Galaxy S22.
    • Wearables & iPads: These devices generally support a single eSIM profile, so no additional action is necessary. Check our Tutorials for set up steps.
