Tips’n'Tricks of Nokia
I accept no responsibility of any kind for damage done to your phone whilst trying these tricks. I have included this information for educational purposes only.
Below are various TIPSnTRICKS based on the Nokia mobile phones. Different ones will work for different models, but most of them will work for all models.
To check the IMEI (International Mobile Equipment Identity) Type-
*#06#
Information you get from the IMEI-
XXXXXX XX XXXXXX X
TAC FAC SNR SP
TAC = Type approval code
FAC = Final assembly code
SNR = Serial number
SP = Spare
To check the phones Software revision type-
*#0000#
Information you get from the Software revision-
V 05.31
18-02-99
NSE-3
1ST Line = Software revision
2ND Line = The date of the software release
3RD Line = Phone type
To enter the service menu type-
*#92702689# (*#WAR0ANTY#)
Serial number (IMEI)
Production date (MM/YY)
Purchase date (MM/YY) You can only enter the date once.
Date of last repair (0000=No repair)
Transfer user data to another Nokia phone via Infra-Red
Clock Stopping
To check weather your SIM Card supports clock stopping type-
Please not this is not for free calls. This feature is to check weather your sim card supports “Clock Stopping”. If your sim does support it, your phone will consume less battery power than if it didn’t support it.
*#746025625# (*#SIM0CLOCK#)
Revealing the Headphone and Car-Kit menus
Please note that if you do these next tricks, the new menus can’t be erased without restoring the factory default settings. To do these tricks you need to short-circuit the pins on the bottom of the phone next to where you plug in you charger.
1. To activate the “Headset” menu, you need to short-circuit pins “3″ and “4″. After a short time the word “Headset” will be shown in the display. Menu 3-6 is now enabled.
2. To activate the “Car” menu, you need to short-circuit pins “4″ and “5″. After a short time the word “Car” will be shown in the display. Menu 3-7 is now enabled.
THE REBOOT TRICK
This should work on all software versions of the 6110.
1. Go to the Calendar (Menu-8)
2. Make a note or reminder.
3. Enter some text into the edit box.
4. Hold “Clear” until the whole text is cleared, then press “Back”.
5. Press “0″. The main screen will now be showing but a space appears on the screen. (you can’t see it)
6. Enter 4 digits (e.g. 1234).
7. Use the down arrow to move the cursor to the left side of the numbers and the space (Down arrow twice).
8. Now enter 6 digits and press the call button.
Wait for a few seconds, the screen should start to flash and reboots. It should alsowork on other menus like the “Profiles” menu.
EFR CALL QUALITY
To activate EFR (Enhanced Full Rate) Enter the code-
*3370#
This improves call quality but decreases batterylife by about 5%
To deactivate it, Enter the code-
#3370#
THE JAMES BOND TRICK
If you short-circuit theleft 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.
CHECK SIM-LOCK
Note – If you bought your Nokia on UK Vodafone or UK Cellnet you do not need to check this because they both transmit on GSM900, and they don’t lock the phones. However if you bought your phone on UK Orange or UK One2one your phone may be blocked. The reason is that they both transmitt on GSM1800. To make a call on GSM1800 you need what is known as a “Dual band” phone. A dual band phone is able to transmit on both GSM900 and GSM1800, so they lock the phones so you can’t use it with any other network simcard. If you find that your phone is locked you can try different software to unlock it. (I havn’t found one that works yet), or you can ask your service provider who will gladly exchange the 10 digit code for about £35.
This is how to check the status of the 4 different locks. Also don’t try entering the wrong number, because after 3 times it will block the phone for good.
There are 4 different locks on your Nokia phone.
COUNTRY-LOCK
NETWORK-LOCK
PROVIDER-LOCK
SIMCARD-LOCK
The code to read out the sim-lock status of your phone is
#PW+(MASTERCODE)+(Y)#
# = DOUBLE-CROSS
W = PRESS “*” THREE TIMES
P = PRESS “*” FOUR TIMES
+ = PRESS “*” TWO TIMES
MASTERCODE = 1234567890
Y = NUMBER 1 TO 4
The master code is a secret code. The code has 10 digits, To read out the sim-lock status you can enter every combination you want!
“Y” Shows the status of the network-lock. Here you can enter a number from “1″ to “4″. The “4″ is for the sim-card lock.
SIM-LOCK CHECKS
#PW+1234567890+1# = GIVES PROVIDER-LOCK STATUS
#PW+1234567890+2# = GIVES NETWORK-LOCK STATUS
#PW+1234567890+3# = GIVES COUNTRY-LOCK STATUS
#PW+1234567890+4# = GIVES SIM-CARD-LOCK STATUS.
