Update a SIM Card or Device IMEI Number

For the steps on updating a SIM card or device IMEI number in AT&T Premier click here.


Copy your contact information to your new SIM card before you replace the old one. To learn how to do so, see Transfer Contacts and Content Between Phones. You won't be able to copy your contacts after you replace your SIM card.
