Personal unblocking key (PUK) codes
PUK and PUK2 codes are used to restore blocked PIN and PIN2 codes.
Both PUK and PUK2 codes are eight characters in length and cannot
be changed. PUK and PUK2 codes must be obtained from your
wireless provider.
Important: If you enter an incorrect PUK or PUK2 code 10 times in
succession, the message SIM rejected appears in the display and
the SIM card can no longer be used. You must contact your wireless
provider for a new SIM card.
• USE CALL RESTRICTIONS
If supported by your SIM card, this feature lets you restrict your outgoing
calls to phone numbers included in the list or beginning with the same
digit(s) as an entry in the list.
Note: If you turn fixed dialing on and don’t have any numbers in
the fixed dialing list, you can’t make any calls!
Note: When calls are restricted, calls may be possible to
emergency numbers (for example, 911 or other official emergency
number). However, one-key dialing may not operate depending on
the type of restriction you chose.
