Can I use a t-mobile Sim with an att phone?

Can i use my tmobile sim card on a at&t phone?

  • My friend gave me her at&t phone Can i use my sim on it? Not sure if its unlocked, so what would happen if it wasn't unlocked?

  • Answer:

    You can use your sim, BUT the must be unlocked. Any good telephone store can unlock it for $15-25. You can have your friend call ATT and ask them for the unlock code which they may give you. Warning: do not try to unlock the phone more than 3 times. It will completely lock and only the manufacturer can unlock it.
