Hi all.

I'll give some secret codes, so that you don't need to search. (if you know more codes, please let me know.)

Nokia Secret Codes

On the main screen type

*#06# for checking the IMEI (International Mobile Equipment Identity).

*#7780# reset to factory settings.

*#67705646# This will clear the LCD display(operator logo).

*#0000# To view software version.

*#2820# Bluetooth device address.

*#746025625# Sim clock allowed status.

*#62209526# - Display the MAC address of the WLAN adapter. This is available only in the newer devices that supports WLAN like N80

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

*#92702689# - takes you to a secret menu where you may find some of the information below:

1. Displays Serial Number.

2. Displays the Month and Year of Manufacture

3. Displays (if there) the date where the phone was purchased (MMYY)

4. Displays the date of the last repair - if found (0000)

5. Shows life timer of phone (time passes since last start)

*#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* - (EFR) deactivation. Phone will automatically restart. Increase battery life by 30% because phone receives less signal from network.

*#4720# - Half Rate Codec activation.

They aren't exactly secret as they have all been posted on this forum many times and 1000's of other sites.

Many of them don't even work on models from the last four years or so.

Not only that, but idf they really were "secret" codes, you wouldn't be allowed to publish them here

They are called "secret codes", but i didn't say that they are really secret!
