9. If AT$NETIP returns all zeros, send the following
command: AT$CGEER<CR>
• There are three common responses:
• $CGEER: no PDP reject cause (Everything
should be working OK)
• $CGEER: requested service option not
subscribed (APN is incorrect or SIM has not
been enabled for data mode.)
• $CGEER: user authentication failed
(username and/or password is incorrect.)
10. Configure the SA-G+ to access the Enfora Server.
Note: To configure the SA-G+ for server
interoperability, several things have to be addressed:
• Most GPRS configurations are Mobile Originate
only. The mobile SA-G+ must initiate a conversation
with a remote server before the remote server can
talk to the SA-G+.
• IP addresses are dynamically assigned and can
change.
