Thread: (ATT) i NEED A RESTRICTION/UNLOCK CODE. pelase helpppp?

Okay my phone randomly wont charge :P
so i found another phone from at&t and it's a Nokia 6820b
I need to unlock it though, because when i put in my sim card it says "insert sim card" still.

So, i took out my sim card and entered the code:
#pw+352968000857963+7#

when i pressed "OK" it said "cannot undo restriction"
can someone help me undo restriction? this is the only other phone i have..

hi restriction code is nothing but the mobile is restricted to particular network sim so it wont accept other network sim .to solve this problem you can use codes .you can get the codes from here superunlockcodes here they ask the following details before providing the codes they
are mobile model,country and the provider to which the mobile is locked then the imei number of the mobile.then they send the codes to unlock the mobile.once your mobile get unlocked then it will be free to accept any network sim.
