Access Code
The following section describes various security codes.
PIN code (4 to 8 digits)
The PIN (Personal Identification Number) code protects your
SIM card against unauthorized use. The PIN code is usually
supplied with the SIM card. If you input the incorrect PIN
code entry three times in a row, the PIN code will be
blocked. If the PIN code is blocked, you need to unblock the
PIN code before you can use the SIM card again. See
information on the PUK code.
PIN2 code (4 to 8 digits)
The PIN2 code, supplied with some SIM cards, is required to
access some functions, such as call cost counters.
Lock code (4 digits)
The lock code can be used to lock the handset and keypad
to avoid unauthorized use.
The factory setting for the lock code is 1234. To avoid unauthorised
use of your handset, change the lock code. Keep the new code
secret and in a safe place separate from your handset.
NOTE
Avoid using access codes similar to the emergency numbers, such as
112, to prevent accidental dialing of the emergency number.
