hardware for it. Sixth, the number of hours the phone has been on. Some of these dates

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
