10.2 Protecting Your Phone

Protecting your SIM card with a PIN
You can protect your SIM card from unauthorized use by assigning a PIN (personal
identification number).
To enable the SIM card PIN
1. Press HOME > MENU, then tap Settings.
2. Tap Security > Set up SIM card lock and then select the Lock SIM card check
box.
3. Enter the default SIM card PIN using the keyboard, then tap OK. To change
the SIM card PIN, tap Change SIM PIN.
Tip
Emergency calls can be placed at any time, without requiring a PIN.
To restore a SIM card that has been locked out
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.
Tap 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#.
