i think you stole the phone
because if you bought it then you should know your phone lock code
i don't think anyone here will like to help you , if it is stolen
hmm.. well.. u see.. it is a 2nd hand phone.. and it is my first time using SE.. so i think you should think again before saying something like that..if i'm aware of the phone unlock code, this might not happen..i just use sim lock since the day i own my first phone..
