Protect Your SIM Card With the SIM Lock Password

You can protect your SIM card against unauthorized use with a personal identification number (PIN). After a PIN is enabled to lock your SIM, you will need to enter the PIN each time you turn on the device in order to unlock your SIM.

NOTE: The SIM card will be permanently locked if you enter the incorrect PIN for three consecutive times. You must then enter the Personal Unblocking Key (PUK) to unlock the SIM card. Please contact your service provider to obtain the PUK.

NOTE: You can make emergency calls without unlocking the SIM.

To enable the SIM card PIN

1Touch the Home button → Menu button → Settings→ Security & location→ Set up SIM card lock→ Lock SIM Card, or

touch the Application button → Settings icon → Security & location→ Set up SIM card lock→ Lock SIM Card.

2Type your SIM card PIN using the on-screen keyboard, and then touch OK.
