for an APN = “gprs02.Motient.net”.
After the template file has been loaded, and the APN entered, click the Write

.
Click the Reset icon to restart the modem. The other ways to reset the modem
are by pressing the reset button on the front of the modem or removing the
power from the modem.
Click the Disconnect icon to terminate communications with the modem.
Unless you click the Write command, changes made in the New
Value field will not be sent to the modem. For some changes
(e.g., baud rate) you must also Reset the modem before the
changes will take effect. NOTE
5.2 Dynamic IP Address
“Data Plan” accounts setup through AT&T/Cingular are provided with a
Dynamic IP address. Dynamic IP addresses are granted only when the modem
is connected and can change each time the modem reconnects to the network.
AT&T/Cingular offers a free Dynamic DNS service that translates a dynamic
IP address to a fully qualified domain name, so that the modem can be
contacted by name as if it had a Static IP.
The domain name used by LoggerNet is: 1xxx.internet.mycingular.com, where
“xxx” is the 10-digit MSISDN associated with the account, and
“internet.mycingular.com” is AT&T/Cingular’s DDNS. No “Dynamic IP”
modem settings are required when using AT&T/Cingular’s DDNS service.
