change the default security code 0000 to any three- to eight-digit personalized
code.
The phone lock has two levels: Full Lock and Autolock.
Full Lock

time you turn on the phone. The message is followed by the prompt Enter lock
code . You then have to enter your code followed by Y E S to use it.

code do not appear until a different SIM card is inserted in the phone. After the
