I forgot the security code for nokia 5200
Imei 357689012869904
would somebody help me

Hi your master code is 6216135137
This code only works if the phone asks for the code when the phone is first switched on. The code will not work if the wrong has already been entered more than 5 times, if it has then the phone is HARD locked and you will need a flash lead and un-locking software as no phone shop unlocks phones anymore ( Incase it's Stolen).
