The majority of mobile phones offered by AT&T have built-in frequencies and features that allow them to function efficiently when you travel overseas to other countries. To use your AT&T phone overseas, you will be required to activate a roaming feature on your phone account that allows you to connect to the mobile phone towers at your overseas destination. If you do not want to activate the roaming feature or pay the additional rates for phone calls, messaging, and data capabilities, you can contact AT&T to have your phone unlocked so you can use an international prepaid Subscriber Identity Module (SIM) card.

    What do I do if my SIM card is blocked if I got it from an overseas carrier?

    When it says your SIM card is blocked, it most likely means that your phone is locked and you need to call your carrier to have it unlocked. See Method 2.
