10.2 Protecting Your Phone
Protect 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, and then touch Settings.
2. Touch Security, scroll down the screen, and then touch Set up SIM card lock.
3. Select the Lock SIM card option.
4. Enter the default SIM card PIN using the keyboard, and then touch OK.
5. 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.
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 wireless
service provider when you received your SIM card.
Touch Emergency Dial and enter this sequence on the keypad:
**05*[PUK code]*[new PIN]*[new PIN]#
For example, if your PUK code is 888888 and you would like to reset the SIM card
PIN to 7777, enter the following in Emergency Dial:
**05*888888*7777*7777#
