Shortcut for Last Dialed call menu
If you for some reason don't want to enter the 'Last Dialed calls menu' by using the 'YES' key you can use the following key stroke instead: First '0' then '#'.

Access menu without Sim card
To access to the menu in your phone without having a card inside do the following: 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. NOTE if you try this on your phone may stop at Keylock On? menu and you´ll have to take your battery out to turn the phone on again. And this will not care about Phone lock!

A way to (un)lock your cell phone on to the network(subset):
1. Press <**<
2. Then on the display appear and give you two choices: Lock to Network ? and Lock to Network subset? (Use arrow keys to select)
3. Enter the NCK number (code is provided by the SP)
4. You have 5 attemps to do this
5. Then your cell phone will work 'only' with the network
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.
