Software Version
*#0000# shows the software version
Signal Processing
*3370# – Enchanced full Rate Codec (EFR) activation. It will automatically restart.
#3370# – Enchanced full Rate Codec (EFR) deactivation
*4720# – Half Rate Codec activation. It will automatically restart.
#4720# – Half Rate Codec deactivation
Enchanced Full Rate will give you much better sound quality when you enable it. The new Enhanced Full
Rate CODEC adopted by GSM uses the ASELP (AlgebraicCode Excitation Linear Prediction) compression
technology. This technology allows for much great voice quality in the same number of bits as the older
Full Rate CODEC. The older technology was called LPC-RPE (Linear Prediction Coding with Regular Pulse
Excitation). Both operate at 13 kilobits.(but you take up more space on the network, so they can charge
you more) – Talk-time is reduced with about 5%
Sim Clock Stopping
*#746025625#
[*#sim0clock#]
Checks if the sim clock can be stopped. Sim clock stop is a kind of stand-by mode which will save battery
time. This code doesn’t work with software version 4.59.
It will tell you if it can be stopped or not.

like the counters in the call register.

Nokia Speed Trap Detector Urban Legend spread by Nokia Engineers ;^)
The settings for radar speed traps detector. Your Nokia cell phone can be programmed to pick up radar
speed traps, when programmed your cell phone picks up the radar and alerts you on the message alert
tone. ( Doesn’t work with Nokia 7110! )
1. Enter your menu
2. Select settings
3. Select security settings
4. Select closed user group
5. Select on
6. Enter 00000
7. Press ok
8. Clear back to normal, within a few seconds your phone will display a radar sign with five zero’s next to
it. It is now activated.
Unfortunately only Nokia phones have this function. The Cell Phone info display needs to be de-activated.
Settings -> Phone Settings -> Cell Info display. Each time you turn off your phone, or even each time you
loose contact with your carrier, you’ll have to activate it again… It is done using steps 1 through 5 above,
but the number (00000) will be already on the field as a default.
The James Bond Trick
If you short-circuit the left middle and right pins on the bottom of the phone with all connections touching
each other, the Nokia software hangs! The profile “Headset” will be activated. Before you do this just
activate the “Automatic Answer” in the headset profile and set the ringing volume to “Mute”. Now you can
use your phone for checking out what people are talking about in a room. Just place it under a table in a
room and call it. The phone receives the call without ringing and you can listen to what people are saying!
Network Monitor
There is a hidden menu inside your Nokia phone. If you want to activate it, you’ll have to re-program some
chips inside of your phone.
Check your software version. You can only continue if you have v4.33, v4.73 or v5.24.
Take apart the phone.
De-solder the EEPROM (ATMEL AT 24C64)
Read out the data with an EEPROM programmer and save it to a file (Backup)
If you have v.33 or v4.73, change the address “03B8″ from “00″ to “FF”
If you have v5.24 then change the address “0378″ from “00″ to “FF”
Write the new data to the EEPROM and solder it back to the phone
Power on your phone and you should have “Netmonitor” enabled.
The Network Monitor gives you the following information:
Carrier number, MS RX Level in DBM, Received signal quality, MS TX power level, C1 (Path loss criterion, used
for cell selection and reselection). The range is -99 to 99, RTL (Radio link timeout), Timeslot, Indication of
the transmitter status, Information on the Network parameters, TMSI (Temporary Mobile Subscriber
Identity), Cell identification (Cell ID, Number of cells being used), MCC (Mobile country code), MCN (Mobile
network code), LAC (Location area code), Ciphering (On/Off), Hopping (On/Off), DTX (On/Off), Discard cell
barred information.Now Enjoy!!!!!!!!!!!!
