Enter your PIN
If your SIM card is preset with a PIN (personal identification number), you will be
prompted to enter the PIN to proceed. Enter the SIM PIN, and then touch OK.
To know how to enable or disable the SIM PIN, see “Protecting Your Phone” in
Chapter 10.
Note If you entered the wrong PIN three times, the SIM card will be blocked. If this happens,
you can unblock it with the PUK (PIN Unblocking Key) obtained from your wireless
service provider.
To turn off the phone
Press and hold the END CALL/POWER button for a few seconds.
When the Phone options menu appears, touch Power off.
Touch OK when prompted to turn off the phone.
Turn off the screen when not in use
To save battery power, the phone automatically turns off the screen when you leave
it idle after a certain period of time. You will still be able to receive messages and
calls while the phone’s screen is off.
Tip For information on how to adjust the time before the screen turns off, see “Display
settings” in Chapter 10.
You can also turn off the screen quickly by pressing the END CALL/POWER button.
Pressing any of the control buttons again or incoming calls will turn on your phone
screen.
Note If you have set up a screen unlock pattern, you will be prompted to draw the pattern
on the screen before it unlocks. For more information on how to create and enable
the screen unlock pattern, see “Protecting Your Phone” in Chapter 10.
