Protecting Your SIM Card with a PIN
Every SIM card comes with a PIN. The initial PIN is provided by
your mobile phone carrier. It’s best to lock your SIM card as
soon as you can.
1.
Press Home key > tap
> Settings > Security > Set
up SIM card lock.
2.
Choose the SIM card you want set.
3.
Tick the Lock SIM card check box.
4.
Enter the PIN you’ve been given and tap OK.
TIPS: If you enter the wrong SIM PIN more times than allowed,
your SIM card will be locked and you cannot access the mobile
phone network. Contact your operator for a PIN Unlock Key
(PUK) to restore the SIM card.
Changing Your SIM PIN
You can change the PIN you’ve been given to one easier for you
to remember and harder for others to guess.
1.
Press Home key > tap
> Settings > Security > Set
up SIM card lock.
2.
Make sure you already tick the Lock SIM card check box.
3.
Tap Change SIM PIN.
