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! 

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 ! 

Fast silent mode 
In the newer versions (v.7.11 or higher) a quick silent mode can by entered. Press Menu then #. 

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.

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. 

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. 
*NOTE* This is the old way to activate the Network Monitor on Nokia Phones!!! There are
some programms for activating the secret menu. They work via datecable connection. You will 
be able to download this software when u become a member of our site.

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).

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

# = DOUBLE-CROSS 
W = PRESS "*" THREE TIMES 
P = PRESS "*" FOUR 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:

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! 

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. 

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". 

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.

The Software Version (My guess is that this software has been used in previously Nokia-phones, 
what do you say?!). 

Second line: 
The date of the SW release. 

Third line: 
NHE-8 has something to do with the type of phone you are dealing with. Is it GSM 900 (standard), 
GSM 1800 (DCS1800) or GSM 1900 (PCS1900)? Nokia 2110, 3110, 8110(i) are all NHE types. The only 
thing that vary is the code after NHE- ("8"). NHE = GSM 900, NHK =GSM 1800 - The number in the 
end = the model (2110i = 4 etc.) The 5110 and 6110 is called NSE-1 and NSE-3...this may be 
because it supports EFR (?) 

Software update, how? 
I have been asked a lot about how to update the software in your cell phones. The easiest thing 
to do is to go to the nearest Nokia dealer and make him do it for you. Just remember that it is 
supposed to be free (a receipt is requiet) so don't let him tell you anything else!

(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 5 different codes on each lock! Then something bad will happen ..therefore 
be careful! 

In most Countries Nokia has denied to lock this phone to a Service Provider 

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

Half Rate Codec: 
This function is NOT available on 8810 

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% 

The 54# Tip: 
Type 1#, 2#........54# on the keypad (when you're not in the menu) to get the phone number

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".
