Security

You can use a PIN code, phone password, and SIM card lock
authentication to prevent unauthorized use of the phone.
PIN Code
A PIN (Personal Identification Number) code is a password provided
by a network operator. When PIN code authentication is activated, it
will prevent unauthorized use of the SIM card. Unless the correct PIN
code is entered when the phone is turned on, the SIM card cannot be
used, even if it is inserted in another phone.
If the PIN code is entered incorrectly three consecutive times,
this will cause the SIM card to lock down, and a PUK1 code
!
provided by the network operator will be required to unlock it.
After unlocking, the PIN code will be automatically set to activate
once the phone is turned on.
PIN Code
Used to activate/deactivate or change the PIN Code. Before
changing settings for the PIN Code feature, the previously set
PIN Code must be entered.
If you wish to change the PIN Code, you must press
Enable item to select On, so that you will be able to enter and
confirm the new password.
PIN2 Code
Used to change the PIN2 code. The procedure is the same as for
the PIN Code.
