The following section describes various security codes
used on your phone.
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 PIN1 code is blocked, you
need the PUK 1 code to unblock 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
The lock code can be used to lock the phone and keypad
to avoid unauthorized use.
PUK and PUK2 codes (8 digits)
The PUK1 (Personal Unblocking Key) code is required to
unblock a blocked PIN1 code. The PUK2 code is required
to unblock a blocked PIN2 code. If the codes are not
supplied with the SIM card, contact the operator whose
SIM card is in your phone for the codes. You can change
the following codes: lock code, PIN code, and PIN2 code.
These codes can include the numbers from 0 to 9 only.
Call Barring Password (4 digits)
The call barring password is required when you use the
Call Barring function. You obtain the password from your
service provider when you subscribe to this function. You
can change this password using the Call barring menu
option. (For further details, see Security Settings on page
74.)

Access codes
NOTE:
The factory setting for the lock code is 1234. To avoid
unauthorized use of your phone, change the lock code. Keep the
new code secret and in a safe place separate from your phone.
NOTE:
Avoid using access codes similar to the emergency
numbers, such as 112, to prevent accidental dialling of the
emergency number.
