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 the unauthorized use. The PIN
code is usually supplied with the SIM card. If you input
the incorrect PIN code entry for 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 the information on the
PUK code.
PIN2 code (4 to 8 digits)
The PIN2 code, supplied with some SIM cards, is
required to access to some functions, such as call cost
counters.
Lock code (4 to 8digits)
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
unauthorized use of your handset, change the lock code. Keep
the new code secret and in a safe place separate from your
handset.
