The following options are available:
Disable: the phone connects directly to the
network when you switch it on.

phone is switched on.
To change your PIN, see the Change PIN menu
option below.
Change PIN
This feature allows you to change your current PIN
to a new one, provided that the PIN check feature is
enabled. You must enter the current PIN before you
can specify a new one.
Once you have entered a new PIN, you are asked to
confirm it by entering it again.
