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.
