WARNING: Using secret codes may be harmful to your phone and result in disabling or worse. Use these codes at your own discretion, we accept no responsibility for blocked pones while using these codes!!!

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%

IMEI Number *#06# Cells Identity Code (IMEI = International Mobile Equipment Identity) XXXXXX XX XXXXXX X TAC FAC SNR SP TAC = Type Approval Code (first 2 digits = country code of the approval-country ) FAC = Final Assembly Code: (01,02 = AEG) (10,20 Nokia) (40,41,44 Siemens) (30 Ericsson) (50 Bosch) (51 Sony,Siemens,Ericsson) (60 Alcatel) (65 AEG) (70 Sagem) (75 Dancall) (80 Philips) (85 Panasonic) SNR = Serial Nr. SP = Spare (always "0")

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.

Warranty Menu *#92702689# takes you to a secret menu with 6 choices: [*#war0anty#] 1. Displays Serial Number. 2. Displays the Month and Year of Manufacture (0997). 3. Displays (if there) the date where the phone was purchased (MMYY). 4. Displays the date of the last repair - if found (0000). 5. Makes you capable of transferring user data if you have the gear for it. 6. Shows how long the phone has been used to talk. This counter is not reset by when you

"clear timers" like the counters in the call register.

Bypass the SP lock With a Nokia 16xx/21xx/31xx/51xx/81xx 1. Insert SIM card of different provider. 2. Turn on the phone and press the UP VOLUME key for 3 sec. Then release it and the phone says PIN CODE? 3. Press the "C" key. 4. Then Press and wait until it disappears and appears again, then press one more time and 04PINPIN*PIN#

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.

Game Hacking with Blizzard

Get the file called the 'BlizzardN-GAGE.SIS' from IRC get in #mediaplace on Efnet (note:

cellphone automatically generates the corresponding GSM network command string and transmits

it to the network. These commands can however be manually entered via the keypad.

Each command is prefixed with either one or two * or # characters as follows: Register and Activate * Activate ## De-Register (and Deactivate) # Deactivate *# Check Status © Call button

Once each command has been entered, if it is a network command (as opposed to a local

handset command) it must be transmitted to the network by pressing the YES (receiver) key

which acts as an enter key - this is represented here with the © character. Always enter

numbers in full international format +CountryAreaNumber ( e.g. +447712345678).
