Device and SIM card security

To change the PIN code, select Phone and SIM card >
PIN code. The new code must be 4 to 8 digits long. The
PIN code protects your SIM card against unauthorised use
and is provided with the SIM card. After three consecutive
incorrect PIN code entries, the code is blocked, and you
need to use the PUK code to unblock it before you can use
the SIM card again.
To set the keypad to lock automatically after a defined
period, select Phone and SIM card > Keypad autolock
period.
To set a time-out after which the device is automatically
locked and can be used only if the correct lock code is
entered, select Phone and SIM card > Phone autolock
period. Enter a number for the time-out in minutes, or
select None to set off the autolock period. When the device
is locked, you can still answer incoming calls, and calls may
still be possible to the official emergency number
programmed into your device.
To set a new lock code, select Phone and SIM card > Lock
code. The preset lock code is 12345. Enter the current code
and then the new code twice. The new code can be 4-255
characters long. Both alphabets and digits can be used,
and both uppercase and lowercase alphabets are possible.
The device notifies you if the lock code is not properly
formatted.
