186  Managing your Phone

You can protect your SIM card from unauthorized use by assigning a PIN (personal 

identification number).

Press HOME > MENU, then touch Settings.

Touch Security, scroll down the screen, then touch Set up SIM card lock.

Select the Lock SIM card option.

Enter the default SIM card PIN using the keyboard, then touch OK.

To change the SIM card PIN at any time, touch Change PIN code.

Tip 

Emergency calls can be placed at any time, without requiring a PIN.

If you enter the wrong PIN more times than the maximum number of attempts 

allowed, your SIM card will become “PUK-locked.” You need a new PUK code to 

restore access to the device. This code may have been provided by your operator 

when you received your SIM card.
Touch Emergency Dial and enter the following sequence on the keypad: 
* * 0 5 * [PUK code] * [new PIN] * [new PIN] #
For example, if your PUK code is 888888 and you would like to reset the 

PIN on your SIM card to 7777, enter the following into Emergency Dial: 

**05*888888*7777*7777#.
