Important! Avoid using access codes that are similar to emergency numbers, such as 911, to
prevent accidentally dialing an emergency number.
Phone Password
The Phone Lock feature allows you to set a password to protect your
phone against unauthorized use. For instructions, see the Security section
in “Phone” on page 151.
PIN
The Personal Identification Number or PIN (4 to 8 digits) protects your SIM
card against unauthorized use. It is usually supplied with the card.
If you enter an incorrect PIN three times in succession, the code is disabled
and cannot be used until you re-enable it by entering the PUK (see below).
For instructions on activating or deactivating the PIN Check feature and
changing the PIN, see the Security section in “Phone” on page 151.
PUK
The 8-digit PUK (PIN Unblocking Key) is required to change a disabled PIN. If a
PUK was not supplied with your SIM card, contact your service provider.
To re-enable your PIN:
1. Enter the PUK and touch Confirm.
2. Enter a new PIN of your choice and touch Confirm.
3. When the Confirm PIN Code message displays, enter the same code
again and touch Confirm.
If you enter an incorrect PUK ten times in succession, the SIM card
becomes invalid. Contact your service provider for a new card.
