Security

■
When security features that restrict calls are in use (such as call restriction, closed user
group, and fixed dialing) calls still may be possible to the official emergency number
programmed into your phone.
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 restrictions — to restrict incoming calls to and outgoing calls from your
phone (network service). A restriction password is required.
Fixed dialing — 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.
