You can use the access codes described in this section
to avoid unauthorised use of your phone. The access
codes (except PUK and PUK2 codes) can be changed
by using the

feature [Menu-9-5-5]. See
page 86.
PIN code
(4 to 8 digits)
The PIN (Personal Identification Number) code pro-
tects your SIM card against unauthorised use. The PIN
code is usually supplied with the SIM card. When the
PIN code request
is set to
On
, your phone will request
the PIN code every time the phone is switched on.
When the
PIN code request
is set to
Off
, your phone
connects to the network directly without the PIN code.
PIN2 code
(4 to 8 digits)
The PIN2 code, supplied with some SIM cards, is
required to access functions such as
Advice of Call
Charge
and
Fixed Dial Number
. These functions are
only available if supported by your SIM card.
PUK code
(4 to 8 digits)
The PUK (PIN Unblocking Key) code is required to
change a blocked PIN code. The PUK code may be
supplied with the SIM card. If not, contact your net-
work operator for the code. If you lose the code, also
contact your network operator.
PUK2 code
(4 to 8 digits)
The PUK2 code, supplied with some SIM cards, is
required to change a blocked PIN2 code. If you lose
the code, also contact your network operator.
Security code
(4 to 8 digits)
The security code protects the unauthorised use of
your phone.
The default security code is set to ‘
0000
’ and the secu-
rity code is required to delete all phone entries and to
activate the
Reset
Settings
menu. Also, the security
code is required to enable or disable the phone lock
function to prevent unauthorised use of the phone. The
security code default setting can be modified from the
