These codes will work on most Nokia Mobile Phones to activate/deactivate advanced hidden functions that you can’t change through the phone menu
One useful function that all Nokia’s I’ve owned have is “Cell Info Display” which can usually be found in the phones “Display settings” (eg: in a Nokia 1600) or “Phone Settings” (eg: in a Nokia 3315)
If your network supports it, when “Cell Info Display” is enabled, it will display the name of the base station your mobile is currently connected to on the screen eg: when i’m walking around the city it says “Sydney CBD” and when i’m at home it displays the name of my suburb.
To display “p” press “*” three times within one second, To display “w” press “*” four times within one second, To display “+” press twice “*” within less than a second

Nokia Error Messages
Code error – appears if the unlock password entered is incorrect. You need to go through the whole process again, ensuring you enter the correct 10-digit code.
SIM was not restricted – appears if the handset has not been locked to a network. You should be able to use any SIM card in this handset.
Not allowed – If the syntax while entering the unlock password is incorrect, nothing happens. If you have tried to unlock the phone 5 times with an incorrect password any further attempts to unlock the phone will generate this message. The phone will need to be electronically unlocked at a Nokia service centre.
