What is the difference between a SIM and an eSIM?

Subscriber Identity Module is the abbreviation for SIM.  Your phone’s SIM card is a little chip that you slot into your phone. It’s linked to your phone number and serves to identify you as a T-Mobile member. It can also store information such as phone numbers and contact information. T-Mobile offers three different SIM card sizes: regular, micro, and nano.

There is no need to install a SIM card in some phones and devices because an eSIM (embedded SIM card) is built-in. An eSIM is permanently attached to the device and cannot be removed. Some smartphones even have dual SIM capabilities, allowing you to have two phone numbers on one device (one eSIM and one detachable SIM) (for example, a work number and a personal number).

We don’t recommend using your old SIM card,  for the 5G internet speed experience. Activate the new SIM card on your phone.
