If your provider does not appear in the list, you can enter the necessary
connection data manually. You will need the APN (Access Point Name)
and the appropriate telephone number in your provider's mobile tele-
phone network.
 Your provider will supply this information to you upon request.
ቦ
To conclude the configuration of the Internet access, you can activate the
"Keep alive" option. This sets up the UMTS connection so that the connec-
tion is automatically established after switching on the device, and so that
the connection is automatically re-established after being cut off—the
Internet connection is "always on". This function is very useful for conven-
ient access to the Internet or for VPN site coupling.
By activating the "keep alive" function, it is very easy to set up, for exam-
ple, a mobile conference room that enables Internet access and, if need
be, VPN-protected access to company networks from any location.
 Depending on the tariff, always-on Internet connections can give rise
to considerable costs, for example with time-based charging. Please
ensure that you are familiar with the details of your provider's UMTS
tariff.
ቧ Alternatively you can set up a suitable hold time for the UMTS connection.
This means that the Internet connection is not started automatically, but
only when data are to be transferred into the Internet. The connection will
be automatically disconnected if data is not transmitted for the duration
of the hold time.
After setting up the Internet connection, you use LANmonitor to check for
the available mobile telephone networks.
