I have a samsung SGH A177 phone with me. I am using it with AT&T as my service provider. I have been stuck with this problem and can’t seem to find how to get of this unlock code for samsung sgh A177. When I try to access it , it asks for a code. I don’t have any code neither from smsung nor from AT&T.Please tell me from where I would get this code? I have an imei number for the phone if it has something to do with it. Please send your suggestions.
