*#06# for checking the IMEI (International Mobile Equipment Identity) 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

*#0000# To view Software Version.

*#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.

*#92702689# [*#war0anty#]
You don't need the warranty-codes any more - you can just scroll through the information like in any other menu. It has the the same data as 81xx and 31xx phones (with "Edit" button for purchase date, and "User data transfer").

Menu:
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) you can here set the Purchasing Date (Warning: You can only do this once - so be careful what you write...)
4: Displays the date of the last repairment - if found (0000)
6: Does anyone know if this is for upgrading the phone's EEPROM?? (Transfer user data?)

Enhanced Full Rate Codec (EFR):
On: Enter *3370# and EFR will be activated after a reboot of the phone ( consumes more power )
Off: Enter #3370# and EFR will be switched off after a reboot of the phone.

Half Rate Codec:
On: Enter *4720# and Half Rate coded will be activated after a reboot of the phone ( better standby time )
Off: Enter #4720# and Half Rate coded will be de-activated after a reboot of the phone

Enhanced 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%

Half Rate will give you bad soundquality, which gives the serviceprovider the opportunity to have more calls on the network, and you might get a lower charge from them. - Will give you 30% longer talk-time.

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 or the easier way is by using the Software Pclocals and the MBUS cable.

with reprogramming:

1.Check your software version. 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.

with Software Pclocals:

1. You'll need an MBUS cable and
2. After the splash screen of the program, you'll have to set-up the com port where your cable is attached.
3. After "Initializing connection" choose "MR Memory Functions" and once you arrive at this menu choose the menu 6.
4. Then type 243 ad Field Test Display to activate the full netmonitor or 241 to deactivate it.

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.

The Reboot Trick
Should work on all software versions.
1. Go to calendar (menu - 8)
2. Make note / reminder
3. Enter some text into the edit box
4. Hold clear until whole text is cleared, then press Back
5. Press 0. Main screen is shown but a space appears on the screen. You can't see it of course.
6. Enter 4 digits (1234, for example)
7. Use the down arrow to move the cursor to the left side of the numbers and the space (2 times down arrow)
8. Now enter 6 digits and press the green "Call button".

Wait some seconds...the phone will now flash the background light and finally reboot. The trick should also work on other menus like the profile menu...

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.

Service Prover Lock
The service provider (SP) lock is used to lock the cell phone to the SP's SIM card. Once the cell phone is locked to a specific operator, if one inserts a SIM card from a different operator the phone will refuse to accept it! The cell phone will however accept another SIM card from the same operator.

All Nokia phones (2110 and newer) have four different SIM locks which can be used to lock the phone for upto 4 different providers. But most phones with restriction only have one lock activated. ( lock 1)

The main code used in Nokia phones is:
#pw+(master code)+Y#
This code is able to check, activate or remove Sim card restriction (SP-lock).
Use the * key to get the p, + and w chars.
'Y' has to be 1,2,3 or 4 - depending of what lock you what to deal with.

#pw+1234567890+1# for Provider-Lock status
#pw+1234567890+2# for Network-Lock status
#pw+1234567890+3# for Country-Lock status
#pw+1234567890+4# for SimCard-Lock status

# = DOUBLE-CROSS
W = PRESS "*" THREE TIMES
P = PRESS "*" FOUR TIMES
+ = PRESS "*" TWO TIMES
MASTERCODE = 1234567890
Y = NUMBER 1 TO 4

(master code) is a 10 digit code, based on the phones IMEI number.
(I can NOT give you the master code - SO DON'T ASK ME FOR IT !!!!!!!)

Eg. To remove restriction on lock 1 type following code:
#pw+(master code)+1#
If you just want to check your phone use 10 random numbers Eg. 1234567890 as the (master code)
eg. To check if phone if restricted on lock 1 type the following code:
#pw+1234567890+1#

Please NOTE that these codes could be used with care! A user told me that it's only possible to type in about 3 different codes on each lock! Then something bad will happen ..therefore be careful!

How to open lock 1 and 4
You will need Winlock software and MBUS cable to do this. Winlock is a Nokia service program that you can use to open lock 1 and 4, really you are closing locks when you do that, but when you write ????? at MCC+MNC and MSIN text box, the phone don't understand it and consider that it's open.
That trick only works for lock 1 and 4, but not for lock 2 and 3.

1. Install winlock 1.10
2. Connect your MBUS nokia data cable
3. Run Winlock
4. Push Read Phone, if you have Lock 2 or Lock 3 closed you can not open your phone, but you can try change Lock 2.
5. Select State Close in Lock 1 and Lock 4, fill out MCC+MNC and MSIN text boxes with ??????? and Push Close Locks.
6. Now you can use any operator card in your phone. If you get any error when you do that do the following steps:
- Select State Automatic in Lock 1 and Lock 4 and change type to User in Lock 1 and Lock 4, fill out MCC+MNC and MSIN text boxes with ?????????? and Push Close Locks.
- Select State Automatic in Lock 1 and Lock 4 and change type to Factory in Lock 1 and Lock 4, fill out MCC+MNC and MSIN text boxes with ?????????? and Push Close Locks.
- If you continue getting errors you must turn off your phone and reset computer and try again.

How to open lock 2
When operators companies close lock2 you can only use the contract or prepaid card for this operator, but you can use another operator company prepaid card if you know what must write.

1. Install Winlock
2. Run Winlock
3. Configure Winlock. Select menu Winlock->Defaults and change GID byte count to 2.
4. Push Read Phone, and write down GID1 info that appear in lock 2.
5. Insert the prepaid card from a different operator company.
6. We must find out a the GID1 info adecuate for our new prepaid or contract card, take a look at our GID1 list and check if your operator and SIM card type is included, if not try to get a phone that have lock 2 closed and have the SIM card type that you want to use in your phone, and read GID1 info with winlock. You can try to write the most used GID1 codes like 0000,10FF,01FF, or FFFF, etc.
7. Change Lock 2 Type from User To Factory or from Factory to User.
8. Push Close Locks
9. Your phone will be reset every time you push Close Locks, if your card is not acepted the GID1 is not correct, repeat from step 4 until you find the correct GID1.
10. If you get error you must turn off your phone and reset computer and try again.
11. If you want your phone accept your original prepaid card write in GID1 the code you read at step 2 and close locks.

Bypass the SP lock
With a Nokia 16xx/21xx/31xx/51xx/81xx that are SIMlocked to one privider you can bypass the SP lock like this:
1. Insert sim card of diferent 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 desapear and apear again, then press * one more time and 04*PIN*PIN*PIN#

The phone now says: PIN CODE CHANGED (or ACCEPTED) and the SIM card is accepted until you restart the phone again. NOTE: On version 5.04 Nokia has removed this option !

Your number in your display
1. Goto menu 3-7 Call cost settings.
2. Turn ON the Call costs' limit 3-7-1. PIN2 code Required.
3. Put in the limit with the phone number. eg. my phone # is 019 2184697 Enter the limit as 2184697
4. Goto menu 3-7-2 Show costs in. PIN2 code Required.
5. Select Currency.
6. Enter Unit price : 1
7. Enter Currency name as 019 (per my phone # eg. above)
Now the phone number 019 2184697 will remains on the 4th row of the display. Secondly, if you press the # key, it prompt which line to be used; Line 1 or 2.

Larger Number Tip (works in 51xx series)
If you hold the key # while you are in the names list, the telephone number can be viewed larger.

Power Button Tip:
If you press the button for a short moment, the menu with the profiles is shown on the display. If you press one more time, the mobile turns itself off. You can use the up and down cursor keys to scroll and enable a different alert setting.

Crazy 5110
Send a SMS full of . (dots) the it'll go crazy when you scroll the received message in your 5110. It doesn't do any permanent damage...it only goes crazy if you scroll the SMS. I'm not sure if it works with all of the software version but it works with 4.59. Doesn't work on SW version 4.53 ..

The 54# Tip:
Type 1#, 2#........54# on the keypad (when you're not in the menu) to get the phone number used for with this key when speed dialing.

Revealing the Headphone and Car-Kit menus
Please note that if you do these next tricks, the new menus can't be erased without retoring 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.

Free SMS Tip
Set Menu 4-3-3 on Usergroup 666 (work with German Networks)

Quick SMS Typing
When typing SMS messages, you have to wait some seconds before you can type the next letter if it is in the same button than the previous one. For example try to write the word "letter", you have to wait before you can enter the second "t".. A much faster solution is to press the # button twice and then the letter "t" or just press the downbutton once and continue to use the same letter key.

Numbers in SMS
Hold the # key press * three times, the abc or ABC on the upper left of the display switches to 123 and you can write numbers directly. To come back to abc repeat the procedure.

Free Call Tip
NB. The tips needs Net Monitor enabled. Be aware that the trick wil remove Netmonitor in some sw versions like v4.73 and v5.04.

1. Laungh the NetMonitor in your Nokia 51xx / 61xx
2. Execute the test number 497
3. Free calling for about 90 sec should now have been activated.

The trick has not been comfirmed working yet.

New Menu on Emergency Calls
*3001#12345# Brings a new menu that gives you access to the emergency calls ( 911 Etc. ). It will give you FREE calls! (only the ones you put in the emergency!! ) This option will depend on your GSM operator, may be this code will not works and you still can get the bill!

Shortcut for Last Dialed call menu
If you for some reason don't want to enter the 'Last Dialed calls menu' by using the 'YES' key you can use the following key stroke instead: First '0' then '#'.

Access menu without Sim card
To access to the menu in your phone without having a card inside do the following: type **04*0000*0000*0000# When display say "Wrong Pin" press NO and you have access to the all menus: Info, Access, Settings, Calculator, Clock, Keylock On?, Mail, Phone book. NOTE if you try this on your phone may stop at Keylock On? menu and you΄ll have to take your battery out to turn the phone on again. And this will not care about Phone lock!

A way to (un)lock your cell phone on to the network(subset):
1. Press <**<
2. Then on the display appear and give you two choices: Lock to Network ? and Lock to Network subset? (Use arrow keys to select)
3. Enter the NCK number (code is provided by the SP)
4. You have 5 attemps to do this
5. Then your cell phone will work 'only' with the network
Warning: The Service Provider (SP) Lock menu is used to lock the cell phone to the SP's SIM card. Once the cell phone is locked to a specific operator, if one inserts a SIM card from a different operator the phone will refuse to accept it! The cell phone will however accept another SIM card from the same operator. To activate/deactivate this lock one needs a special secret code that is not available to the end user. Your phone can be locked to a service provider FOREVER by doing this! If an invalid code is entered all five times, the menu will exit and be deactivated! Any further attempt to activate the NCK/NSCK lock Menu will result in the response "Not allowed"! However the NCK/NSCK lock can be recover through a direct clearing in the EEPROM.
