Mobile Carrier Settings: Mobile carrier selection allows you to configure the mobile device to
n
use a specific mobile service only. The recommended and normal operation is for the mobile
device to automatically find service with an available carrier. However, you can configure a
manual selection to use a specific carrier. Please be aware that use of a manual carrier
selection can result in a significantly longer time interval for the unit to find service on the
specified network. Both the mobile network and the mobile device (modem) may influence this
behavior. Therefore it is recommended that the Automatic selection be used wherever
possible.
Automatic: Enables automatic selection of a carrier for the mobile service connection. The
l
mobile PPP connection is not automatically restarted if automatic carrier selection is
configured.
Manual: Enables manual selection of the Network ID of a carrier for the mobile service
l
connection. The carrier selection is the concatenation of the Mobile Country Code (MCC)
and Mobile Network Code (MNC) value for a carrier. The MCC is always a three-digit
decimal value, and the MNC is either a two- or three-digit decimal value. A properly entered
Network ID is composed of five or six decimal digits, with no other characters in that value.
The Scan available carriers... link initiates a wizard that instructs the modem to scan for
available carriers and display a list from which the desired carrier may be selected. The
scan may take as little as 20 seconds or up to two minutes to complete. Scanning for
carriers requires that the mobile PPP connection be terminated so the scan may be
performed. Upon completion of the wizard, the mobile PPP connection is restarted using
the selected carrier.
Note If the Mobile Band Settings selection in use by the modem is other than Automatic,
the list of carriers returned by the scan may include only a subset of the carriers available
in the area.
You can manually enter the Network ID from a carrier selection from the list. However, the
mobile PPP connection does not automatically restart if you are using the manual entry
method.
Digi SureLink settings
Use the Mobile Connection Settings to configure Digi SureLink settings for a Digi device. SureLink can
ensure that a Digi device is in a state where it can connect to the mobile network, and you can use
them to monitor the integrity of the established mobile connection.
There are two groups of SureLink settings:

WARNING! The scan for available carriers requires that you terminate the mobile
PPP connection before you perform the scan. You cannot perform and complete a
successful scan if it is initiated over the mobile connection, since the scan
procedure requires user interaction that is not possible after the mobile PPP
connection has been terminated.
