    So I recently sold my phone, and wa wondering. Can I simply remove my sim and restore my phone? My plan is to simply do that, use an older generation phone by moving my SIM card onto it, then wait until the next iPhone come out and upgrade to that. Will that work or cause any problems? Do I need to call AT&T and deactivate my phone? What will that do? Will it completely remove my number from our plan? Or will it just unassociate my number with that specific iPhone?

    Any help is welcome. Perhaps just tell me how you sold your AT&T phone and what you had to do. thanks!

    Take your sim out and restore like you said. You can put your sim in another iPhone no problem.

    Nope! Unlike CDMA devices, the SIM card is the sole thing that controls cellular service with a GSM phone. Remove the card, and that telephone can't make/receive calls etc. with your number. Insert it into a new phone, and that new phone is now activated with your telephone number. If you need a different sized SIM, AT&T can issue you a new correctly sized SIM card, usually free of charge.
