■ Security
When security features that restrict calls are in use (such as call restriction and
fixed dialing) 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 — to set the phone to ask for your PIN code every time the phone
is switched on. Some SmartChip 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 SmartChip 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.
Security level > Phone — to set the phone to ask for the security code whenever a
new SmartChip card is inserted into the phone. If you select Memory , the phone
asks for the security code when the SmartChip card memory is selected, and you
want to change the memory in use.
