■ Security
When security features that restrict
calls are in use (such as call barring,
closed user group, and fixed dialling)
calls still may be possible to the
official emergency number
programmed into your device.
Select Menu > Settings > Security
and from the following options:
PIN code request and UPIN code
request — to set the phone to ask for
your PIN or UPIN code every time the
phone is switched on. Some SIM
cards do not allow the code request
to be turned off.
PIN2 code request — to select
whether the PIN2 code is required
when using a specific phone feature
which is protected by the PIN2 code.
Some SIM cards do not allow the
code request to be turned off.
Call barring service — to restrict
incoming calls to and outgoing calls
from your phone (network service). A
barring password is required.
Fixed dialling — to restrict your
outgoing calls to selected phone
numbers if this function is supported
by your SIM card. When the fixed
dialing is on, GPRS connections are
not possible except while sending
text messages over a GPRS
connection. In this case, the
recipient’s phone number and the
message center number must be
included in the fixed dialing list.
Closed user group — to specify a
group of people whom you can call
and who can call you (network
service).
Security level > Phone — to set the
phone to ask for the security code
whenever a new SIM card is inserted
into the phone. If you select
Memory, the phone asks for the
security code when the SIM card
memory is selected, and you want to
change the memory in use.
Access codes — to change the
security code, PIN code, UPIN code,
PIN2 code, or barring password.
Code in use — to select whether the
PIN code or UPIN code should be
active.
Authority certificates or User
certificates — to view the list of the
authority or user certificates
downloaded into your phone. See
”Certificates” p. 68.
Security module sett. — to view
Secur. module details, activate
Module PIN request, or change the
module PIN and signing PIN. See also
”Access codes” p. xii.
