APN1 – APN3 – APNs are assigned the network operator. The APN determines what IP addresses are assigned to the
mobile station, what security methods are used, and how the GSM data network connects to the customer’s network.
Beginning in release 4.02.02 up to three APNs and their associated authentication information are supported. A pull down
allows one of the three APNs to be selected, or in Auto mode each APN will be used to attempt to make a connection until
the connection is completed. In auto mode during the initial connection the APNs are tried in a round-robin mode starting
with the first populated APN. After the initial connection subsequent attempts to connect to the network will begin with the
APN providing the last good connection. The authentication fields provided for each APN are:


some networks.
