Frequently asked questions

  • What does “Bring Your Own Device” or “BYOD” mean?

    BYOD means you bring your own unlocked, compatible device to AT&T. Even if you didn't buy your device from AT&T, you can activate your phone on a new AT&T plan.

  • What is the biggest benefit of BYOD?

    No contract! Transfer an eligible, unlocked phone you own and love to a new AT&T plan. Or, you can switch a newly-purchased phone from your current provider to AT&T.

  • What is a SIM or eSIM card?

    SIM cards are small plastic cards that are inserted into your phone. They have a unique ID number and store your personal data. An electronic SIM is called an eSIM, and it can be activated over the internet. All wireless phones have SIM cards, but only Dual SIM devices have eSIMs.
