Will Att give you the code to unlock your cell phone?

I bought a used Att cell that I thought was unlocked but isn't. I don't know who to call at ATT to see if they will give me the unlock code.

HI if you want to unlock your phone from AT&T network provider to freely use it with any GSM sim then code is the best solution to unlock it ..You can purchase code from online providers like TheUnlockArena.com for reliable cost .You first check that whether the code is available for your mobile model ,country and network provider .If yes then pay for it and unlock the phone then freely use it with any GSM sim ...
