Before connecting to SIM services, make sure you are within the
coverage area of an access point and connected to a wireless LAN. The
Connect button is activated only when the wireless device has detected
a service in the network, otherwise the button remains inactive.
On the SIM services page, Click Connect.

SIM card and click OK.
Connection to your service provider's network and SIM services is now

established. To disconnect from SIM services, click Disconnect.
The connection to the SIM services is valid only for a certain length of time.
This ensures that you are not accidentally connected to the service for a long
period of time. The length of time varies depending on the network. When
the set time limit is about to end, you are asked if you want to continue or
disconnect. If you do not want to continue, the connection to SIM services is
ended when the specified time expires.
You cannot configure these settings when you are connected to
SIM services. You must end the connection first.
For the changes to take effect, click the Apply button. If you have made
changes to the settings but have not clicked Apply, and now wish to restore
the previous settings, click Restore.
Service provider domain
Type the domain name provided by your service provider or network
operator, as in company.com. You cannot connect to SIM services without
specifying the domain name.
Automatic connection
You can get automatically connected to SIM services when such a service is
detected and available. If you select the Prompt when a service is detected
check box, every time a service is detected you are asked whether you want to
get connected. Once you have confirmed that you want to get connected, the
access controller authenticates you to the service without your having to
click the Connect button.
Advanced connection controlling
Your wireless device sends keep-alive signals on a periodic basis to the access
controller in order to check the validity of the connection. If the wireless
device receives no response, the connection is ended automatically.
If you select the Enable advanced connection controlling check box, your
wireless device and the access controller can exchange additional signals,
which enables a quicker detection of lost connection.
