Managing Your Phone 19
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:
**05*[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#
Protecting your phone with a screen lock
You can further secure your data by locking the screen and/or requiring a screen
unlock pattern every time your phone is turned on or every time it wakes up from
sleep mode (screen is off).
To lock the screen
Press the END CALL/POWER button. Locking the screen prevents accidental screen
touches when the phone is in your bag, purse, or pocket.
To unlock the screen, see “To unlock the screen” in Chapter 1.
To create and enable the screen unlock pattern
You can increase the security of your phone by creating a screen unlock pattern.
When enabled, you have to draw the correct unlock pattern on the screen to unlock
the phone’s control buttons and touch screen.

Tap Security > Set unlock pattern.
