Secret Nokia Phone Codes (Part 1)

If you have a Nokia mobile phone, you can enter these codes to do some nifty tricks and find information about your handset:

IMEI (International Mobile Equipment Identity) Number:

*#06#

The 15 digit number which comes up on your screen is your unique IMEI number, and comprises the following information:

• Digits 1-6: TAC (Type approval code)
• Digits 7-8: FAC (Final assembly code)
• Digits 9-14: SNR (Serial number)
• Digit 15: SP (Spare)

Software Revision Type:

*#0000#

You will see three lines of information on your screen which are comprised of the following:

1. The phone's software version
2. The date of the software release
3. Phone type.

Service Menu:

*#92702689# (*#WAR0ANTY#)

You will find the following menus displayed:

• IMEI
• Production date (mm/yy)
• Purchase date (mm/yy). Note that you can only enter this date once!
• The date of last repair (0000 means that the handset has not been repaired, or at least not reported by an official service centre)
• Transfer user data to another Nokia phone via infared, if this feature is part of the handset.

Clock Stopping:

*#746025625# (*#SIM0CLOCK#)

This checks wether your phone supports this feature. Key in again to restart the clock.

Activate HRC (Half Rate Clarity)

*#4270#
