What is eSIM?

eSIM means "embedded SIM". So an eSIM is a digital SIM card that's built into your phone, your tablet, or your watch.
An eSIM lets you connect to our network instantly, and digitally, so now you can manage multiple numbers on a single phone.

Getting set up is easy too - just download and activate your eSIM, and then connect to our network in a matter of minutes.

A traditional SIM card is a small, physical chip that gets slotted into your phone and connects you to your carrier network. It identifies your phone number, and lets you send text messages, make calls, and use data.​ There are plenty of phones that use a physical SIM card, while newer model phones are introducing eSIM.​
