The following codes work with most mobile handsets.  However, I must emphasize that by entering or carrying out any of the following actions is purely at your own risk.  There are many other codes available, however, if entered in-correctly they can lock your mobile (This is why I haven't listed these) .  There are many other joke codes around which claim to unlock hidden games, radar speed traps etc.. Normally when you enter one of these codes, they will switch your phone to a different language. So be Careful !!

International Mobile Equipment Identity (IMEI)

Type the following:- *#06#

You should receive the following information : -

XXXXXX--XX--XXXXXX--X

TAC-------FAC-------SNR----SP

TAC = Type Approval Code
FAC = Final assembly code
SNR = Serial number
SP = Spare

Every GSM mobile has an unique International Mobile Equipment Identity (IMEI), which is used to identify the mobile phone but not the network subscriber using the phone. In order to maintain the independent identities of the GSM mobile phone and the GSM subscriber, the international mobile equipment identity (IMEI) is completely independent of the international mobile subscriber identity (IMSI) Each GSM network operator maintains three lists of international mobile equipment identities (IMEIs) in its equipment identity register (EIR):

GREY - GSM mobile phones to be tracked, BLACK - barred GSM mobile phones, perhaps those that have been stolen and WHITE valid GSM mobile phones.

Transfer user data to another Nokia phone via Infra-Red
 

Sim Card Clock Stop

Type :- *#746025625# (*#SIM0CLOCK#)

This feature on your Nokia phones does not enable free calls, I thought I should mention this as I have been asked hundreds of times about this ! This feature basically saves battery consumption if enabled.

This improves call quality but decreases battery life by about 5%
