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!
