10-4 Security
If the SIM card has been changed and the
new SIM card has not previously been used
with your communicator, the communicator
locks itself until the lock code, supplied with
the communicator sales package, is correctly
entered. The communicator recognizes five
different SIM cards as the owner’s cards.
PIN code
When the phone interface is switched on,
this setting allows you to change the PIN
code. The changing procedure is described at
the beginning of this "Security" section. The
new PIN code must be 4 to 8 digits long. The
PIN code can also be changed in the phone in-
terface Security options menu (Menu 5 6 2).
The PIN code is supplied with the SIM card
(i.e., the network operator who activates your
SIM will give you the PIN code). When the
PIN code request is enabled, the code is re-
quired each time the phone interface is
switched on. The PIN code request must be
turned on to change the code.
Lock code
This setting allows you to change the lock
code. The changing procedure is described at
the beginning of this "Security" section. The
new code must be 5 digits long. The lock code
can also be changed in the phone interface
Security options menu (Menu 5 6 1).
The lock code is needed to:
• Lock the communicator (except when the
autolock period is in use).
• Unlock the communicator.
• Change the SIM change security setting.
• Turn the Autolock period on or off.
• Open the Telephone application calling card
settings.
You can find the lock code on a sticker in the
sales package of your communicator. Keep it
secret and in a safe place, separate from the
communicator.
Note: If you enter an incorrect lock code (you will
get a code error message) several times in
succession, or misplace or forget your lock
code, the communicator must be sent back
to the dealer to unlock the device.
Network password
The network password is needed to change
call restrictions, see Chapter 4 "Telephone:
Telephone settings" on page 4-1. You obtain
the password from your network operator
when you subscribe to the service.
When the phone interface is switched on, the
setting in the security section allows you to
change the network password. The new code
must be 4 digits long. The network password
can also be changed in the phone interface
Security options menu (Menu 5 6 4).
If the password is changed correctly, the
communicator requests the network to per-
form the desired operation.
Other codes
PIN2 code (4 to 8 digits)
The PIN2 code can only be changed in the
phone interface Security options menu
(Menu 5 3).
The PIN2 code is supplied with some SIM
cards. The PIN2 code is required to access
some functions, such as call charging unit
counters, which must be supported by the
SIM card. If you enter a wrong PIN2 code
three times in succession, the PIN2 code is
disabled and cannot be used any more.
PUK and PUK2 codes (8 digits)
The PUK is supplied with all SIM cards. This
code is required when you want to change a
disabled PIN code. If you enter a wrong PUK
code ten times in succession, the SIM card is
rejected and you cannot make or receive any
calls, except emergency calls. Contact your
network operator for a new SIM card.
The PUK2 code is supplied with some SIM
cards. The code is required when you want to
change a disabled PIN2 code. If you enter a
wrong code ten times in succession, you will
not be able to access the functions which re-
quire the PIN2 code. To utilize these func-
tions, contact your network operator for a
new card.
