I forgot my nokia 1200 security code with IMEI 359328021318979. I'm still using it but I'm not able to put another sim card. Please help me!
Hi,
The master code is a 10 digit number that will always be accepted as if it were your actual security code.
You can use the master code to change your security code back to what ever you like. When your Nokia handset asks you for the security code simply enter the master code.
Your Nokia Mastercode: 1125226534
