Security setup
SIM lock: this function can prevent others from using your SIM
card without your permission. After the SIM card PIN code is
activated, the correct PIN code must be input every time when the
mobile phone is powered on; otherwise you can only make
emergency calls.
Note:
The PIN code is the operating password and associated with
the SIM card. The SIM card will be locked if the PIN code is
entered incorrectly 3 consecutive times. If this occurs, you
need the PUK code to unlock the SIM card. The PUK code may
be provided for you with the PIN code and the SIM card. If not,
contact your network provider.
Fixed dial: after this function is activated, the mobile phone is only
allowed to be used to dial telephone numbers existing in the list. To
turn on this function, you need to input your PIN2 code. Consult
