Get a new physical SIM card

You can get SIM card kits at one of our stores, online through att.com, or from another online retailer. The kits come with three SIM card sizes. Use it if you want to bring your own device to AT&T, or if you just need a new physical SIM.

For your security, only the account owner or retail authorized user can activate a new SIM card. Call us at 800.331.0500 or go to a store.
