Protecting Your SIM 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 as soon as you can.
1. Tap Home Key >
> Settings > Location & security > Set up SIM
card lock.
2. Tick the Lock SIM card check box.
3. Enter the PIN you’ve been given and tap OK.
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. Tap Home Key >
> Settings > Location & security > Set up SIM
card lock.
2. Make sure you already tick the Lock SIM card check box.
3. Tap Change SIM PIN.
4. Enter the old PIN and tap OK.
5. Enter your new PIN and tap OK.
6. Enter the new PIN again and tap OK.
Restoring a Locked SIM Card
Put all your confidential passwords in a safe place for future use. 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.
