Use Virtual Serial Port
If Use virtual serial port is enabled, packet data connections are established through
the virtual serial port of the WWAN driver rather than through the WWAN driver
directly. This checkbox should only be checked if certain third-party VPN (Virtual
Private Network) clients are used that do not work correctly otherwise. The default
setting is disabled (unchecked).
Note: The connection setup takes longer through the virtual serial port.
Enable Automatic Configuration
In most cases, the data connection is configured automatically and no user
interaction is required. This is true even if multiple SIM cards from different
operators are used with the same device. The connection parameters are adjusted
automatically when a new SIM card is detected (this may require a reset). The
connection parameters are retrieved from a database.
Manual configuration should be necessary only if:
One or more parameters in the database are incorrect or a new operator is
not yet in the database. (The database should be corrected for subsequent
software releases.)
An operator has assigned individual packet data user names and passwords.
A very large site has their own APN. Such connections always have to be
configured manually.
A customer has subscribed for a static IP address. By definition this must be
configured manually.
Important: For CDMA/1xRTT, automatic configuration is not available –
connections must be configured manually. Under APN, the
packet service access number must be entered (typically “#777”).
In the following section, all the parameters that need to be configured for a
connection (such as APN, user name, password, DNS server addresses etc.) are
referred to as a profile. Every profile is identified by an arbitrary, unique name. The
profile named Default is special in that it is always present and can neither be edited
nor deleted. (A sample dialog box is presented on the page following.) The Default
profile uses parameters from a built-in database. The home network (the network
that issued the SIM) is used for the database look-up. While there can be many
configured profiles, only one profile can be active at any time.
