The Service Provider (SP) Lock

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.

Here is how to activate the menu :

<**< Lock to Network? if pressing yes you have 5 attempts to enter NCK. <**<< Lock to Network subset? if pressing yes you have 5 attempts to enter NSCK.

Warning: 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.

Battery level Indicator When turned OFF

When the phone is turned off and the phone is not changing - the battery level can be seen for a short period of time by pressing the 'NO' key quick once (it has to be quick!) and then wait for about 2 seconds. The battery level will now be shown in the display at its normal position.

type **04*0000*0000*0000#
When display say "Wrong Pin" press NO and you have access to the all menus: Info, Access, Settings, Calculator, Clock, Keylock On?, Mail, Phone book.
