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

both uppercase and lowercase alphabets are possible. The
device notifies you if the lock code is not properly formatted.
To set the device to ask for the lock code when an unknown,
new SIM card is inserted into your device, select Phone and
SIM card > Lock if SIM card changed. The device maintains
a list of SIM cards that are recognised as the owners cards.
