Security
Setting the phone lock
The phone lock protects your phone from unauthorized use. If you enable phone lock,
you will be prompted to enter a phone lock code before you use the phone.
Select Settings > Security settings > Power-on password to set the phone lock. You
can change the default phone lock code (000000) to a personal password. It is
recommended that you periodically change this phone lock code for enhanced security.
When clearing the user settings, you must enter the correct power-on password.
Setting the keypad lock
In standby mode, press and hold # key to lock the keypad. In this case, you can only dial
emergency numbers and answer incoming calls.
In standby mode, press
Select Settings > Phone settings > Auto keypad lock to set the keypad lock. If
automatic keypad lock function is enabled, the keypad will be automatically locked
when the standby time exceeds the preset period in standby mode.
PIN and PUK

of your SIM card. Personal unblocking key (PUK) code helps change the locked PIN code.
If you enter the wrong PIN code for three times, your SIM card will be locked. In this
case, you need to enter the PUK code to unblock the locked PIN code. Please note that
if you enter the wrong PUK code for ten times, your SIM card will be permanently
locked, you need to consult your service provider to replace your SIM card. PIN code
and PUK code are provided together with the SIM card. For details, consult your service
provider.
