I have seen this sort of secret code idea in several places.
This one is from another Site posted by DEMA on April 20, 2002.
Quote:
Model Number:
7110
Code Title:
The Service provider (SP) lock
Code:
#pw+(master code)+Y#
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 (MCC+MNC)
#pw+1234567890+2# for Network-Lock status (GID 1)
#pw+1234567890+3# for Provider-Lock status (GID 2)
#pw+1234567890+4# for SimCard-Lock status (MSIN)
(master code is a 10 digit code, based on the phones IMEI number) 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)
EXAMPLE: To check if phone if restricted on lock 1 type the following code:
#pw+1234567890+1#
Code Descripion:
This 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.

This is true up to a point.
The 7110 is a DCT3 phone and so has a 10 digit code.
That is: pw+1234567890+1 etc.
Most phones today are DCT4.
They require a 15 digit code.
That is: pw+123456789012345+1
It is true that you can check the lock status by entering a random code.
The problem with this is that each phone only allows 3 to 5 tries to unlock it by entering a code. (Those phones that work with this method)
My understanding is that if you do this you will get ?Code Error? as a response if the ?Lock? is on.
When you do that you use up one of your tries.
That makes it that much more difficult to unlock.
It is better to just try a SIM from a different Network and see if it works.
Just a thought.
