C.ADVANCED SECTION (hmmm lets have some fun)
1 Studying the IMEI number
As you know typing *#06# brings up a 15 digit IMEI number known as INTERNATIONAL MOBILE EQUIPMENT IDENTITY
The format of the code is
XXXXXX XX XXXXXX X
TAC FAC SNR SP
TAC= Type Approval Code
FAC= Final Assembly Code
SNR= Serial number
SP= Spare
Remember that the IMEI number is a unique number.No two phones have the same IMEI number.And the best part ... it cannot be changed by any means(although there are....NEXT POST).
So you need to note down your IMEI no. in case your phone is stolen.
2.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.
3.
Using your phone for spying.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.
4.
Network MonitorThere 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.
1. Check your software version (Refer hack # 2 in the beginner section ). You can only continue if you have v4.33, v4.73 or v5.24.
2. Take apart the phone.
3.De-solder the EEPROM (ATMEL AT 24C64).
4. Read out the data with an EEPROM programmer and save it to a file (Backup).
5. If you have v.33 or v4.73, change the address "03B8" from "00" to "FF".
6.If you have v5.24 then change the address "0378" from "00" to "FF".
7. Write the new data to the EEPROM and solder it back to the phone,
8. 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 statusThis is a detailed explanation of the lock status hacks in the intermediate section.
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 transmits 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 sim card. If you find that your phone is locked you can try different software to unlock it. (we haven'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

Unlock your Nokia PhoneAnd I would like to mention this website I came across
GSM LibertyThis website supports mobile unlocking.For eg. Say you bought a phone from a particular operator X. Now X by default has locked your phone so that it cannot be used with other Operators.
This site gives you free unlock code and they claim to be the best at it.
Also they have a very good forum and a very organized and informative support center.
Check the site out.
