These codes for the Nokia series of phones provide some interesting information for users, they also unlock some hidden functions. Use the codes at your own risk, not all Nokia phones support all codes, I have tried to split them into these groups.

*#06# :Display the IMEI (Standard GSM command, works on all phones)

*#0000# :Display the firmware version and date

*#92702689# :Here you can view the S/N and the IMEI(International Mobile Equipment Identity) as well as the life timer (newer models). The date the phone left the factory and the date it was purchased. If your phone has been repaired the date of the repair is also visible. You will need to turn the phone off to exit this menu. Newer phones simply require you to press ok.

*4720# :Cctivates Half Rate, Half Rate is 5.6kbit/s and uses half the bandwidth at the cost of call quality. Network operators often activate half rate on overloaded towers during peak times to save costs.

#4720# :Deactivates Half Rate

*3370# :Activates Enhanced Full Rate, EFT attempts to match wire quality. The calls are 12.2kbit/s and are not supported by all operators. It is compatibale with the hightest AMR mode.

*#3370# :Enhanced Full Rate Codec (EFR) activation. Increase signal strength, better signal reception. It also help if u want to use GPRS and the service is not responding or too slow. Phone battery will drain faster though.

*#3370* :Deactivation. Phone will automatically restart. Increase battery life by 30% because phone receives less signal from network.

#3370# :Deactivates Enhanced Full Rate

*#746085685# :Display the SIM clock status

*#7220# :Activate the GPRS PCCCH support (Packet Common Control Channel)
*#7230# :Deactivate the GPRS PCCCH support
*#7760# :Display the manufacturing serial number

*#67705646# :Clear the operator logo, the logo will be reset to the default network operator logo.(This only works on the 3310 and 3330).

*#2820# :Display the Bluetooth MAC address (Phone must have a built in bluetooth adapter)

*#7370925538# :Reset the mobile wallet (Phone must have the mobile wallet feature)

*#7370# :Soft-format the memory (Symbian)

*#7780# :Reset to factory defaults, confirmation required (also known has a Hard-format), all phone contents will be wiped clean including contacts and smses if they are stored on the phone

#pw+1234567890+1# :Shows if sim have restrictions.

*#7328748263373738# :Resets security code.(Default security code is 12345)
