Phone
If you select Manual, the phone will show a list of available networks and you can
select the network you wish to use if this network has a roaming agreement with
your home network service operator. If no such agreement is in force, the text No
access will be displayed and you must select another network.
Confirm SIM service actions (3-2-5)
You can set the phone to show you the confirmation messages sent between your
phone and the network when you are using the SIM services by selecting the
option Yes within the menu 3-2-5 ( Confirm SIM service actions).
Security settings (3-3)
The purpose of the security system is to prevent unauthorised use or altering of
important settings. In most cases, activating or changing the security options
requires the appropriate access code. See ‘Phone security’ on page 215.
Note: When security features which restrict calls are in use (for example, call
barring, fixed dialling, or system lock etc.), calls may be possible to
certain emergency numbers in some networks (for example, 112 or other
official emergency number).
PIN code request (3-3-1)
The options are On and Off. See ‘Phone security’ on page 215.
Call barring service (3-3-2)
Tip: A barring password
is required for using this
function.
This network service allows you to restrict incoming calls to, and outgoing calls
from, your phone.
