This trick works with most of the Nokia phones but exceptions may be there. It most likely won’t work for the newer phones like the Lumia 710 or the Windows phone. By this method you can get the master code of the Nokia phone. These master codes are unique for each phone and can be used in place for the security / phone code. This way if you have forgotten your Security code then you can reset it with this Master code. Following are the steps:
- Get the IMEI number of the phone by pressing *#06# on your phone.
- Go to http://www.nokialockcode.com/calculate.php
- Enter the IMEI number and press generate.
- Congrats! You have the master code. Enjoy
