SP LOCKS.
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 (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)
EXSAMPLE:
To check if phone if restricted on lock 1 type the following code: #pw+1234567890+1#
NOTE that this function must be used with care since it's only possible to type in 3
different codes on each lock! if one types in more than 3 times then phone needs extra care.
