Protecting your SIM card with a PIN

1.  From the main Home screen, press MENU, and then tap  

Settings > Security > PIN code.

.  Enter the current SIM card PIN, and then tap OK.

Note 

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

Unblocking 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 be locked. You need a PUK 

code (PIN Unlocking Key) to restore access. This code may have been 

provided when you received your SIM card. If the PUK code is not 

provided or you lost it, contact your mobile operator.

1.  Enter the PUK code, and then tap OK.
.  Enter a new PIN, and then tap OK.
.  Confirm your new PIN, and then tap OK.

Removing the SIM card properly

1.  Turn off your phone, and then remove the back cover and 

battery. If you’re not sure how to remove them, see “Before 

Turning On Your Phone” in Chapter 1.

.  With your right thumb, press down the small tab located at the 

right side of the SIM card slot.
