alcatel 4052R sim unlock

I have an alcatel flip phone.

I have an AT&T account.

I want to give it to my kid as an emergency phone with a cheap prepaid sim

The phone was sim locked to AT&T

AT&T sent me the unlock code

If I put a sim into the phone, it just says "locked". It does not give me an option to unlock it

Any ideas?

Hello @PuckLoptr,


Thank you for your concern.


With more details, we'd be able to assist you to the best of our ability:

  • Are you trying to unlock your device or SIM?
  • Also, have you repeated the steps once more? If so, do you receive same error message?

Please let us know.
