Lots of time it happens; you forget the security code of your mobile phone. Now if you own a nokia mobile phone , you just need to know your IMEI (International Mobile Equipment Identity) number.
To check your IMEI number, type *#06# on the main screen. This number can also be found on the backside of the handset. Just remove the battery
You can visit a site which will calculate the Master Code of your phone. This code can be used to change your present Lock/Security code.

- The Master Codes are only for DCT-3 and DCT-4 phones.
