Quick answer

What's a SIM card?

What’s an eSIM?


Before you switch SIM cards

Have an eSIM? You can’t move it to another device, so you’ll have to go to a store, or call us to get a new one.

Important: After you swap your SIM card, make sure you call us or go to a store to let us know what new functions your device (IMEI) can do. We will update our network. Otherwise, some features like HD Voice or your voicemail may not work.
