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 re-
quired. 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 pre-
sented 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.
If connection profiles are configured manually then the Enable automatic configuration:
checkbox should normally be unchecked.
In one particular use case, manually configured profiles may be combined with automatic
configuration. If multiple SIM cards are used with the same device, each SIM card being
from a different operator and some or all of them requiring a manually set up profile, auto-
matic configuration may be used to automatically pick the correct manually configured
