You can lock your device with the PIN that is supplied with your SIM or USIM card. Once the SIM or USIM lock is enabled,
you must enter the PIN each time you turn on the device or access applications that require the PIN.

1 In the application list, select Settings → Security → Set up SIM card lock → Lock SIM card.
2 Enter your PIN and select OK.

●● If you enter an incorrect PIN too many times, your SIM or USIM card will be blocked. You must enter a PIN unlock key (PUK) to unblock the SIM or USIM card.

●● If you block your SIM or USIM card by entering an incorrect PUK, take the SIM or USIM card to your service provider to unblock it.
