Oh yes! Good ole S/E cards! The apn you have a grip on but the strangest
oddity in the S/E cards is that it also takes an AT command to turn on the
radio which is what the software manager does when you launch it. I
believe all other brands start the radio as soon as they are plugged in
which makes sense. The command for that is AT+CFUN=1 this can only be a 0
or a 1, 1 is positive or on. The other part is registration AT+CGREG=1.
The biggest pain about this is that the startup will fail the first time
because it takes several seconds or more to power up the radio and let it
find a signal. I use a 30 second holdoff before redialing. The init string
can be concatenated into one string and it won't choke on it. Once you
pass the command to set the radio to ON, it will NOT turn the radio off
unless you unplug the card so the second time you pass the string, it
ignores the AT commands that are already active in the card's current
state and just dials and sets up the connection. It's basically a modem
with a built in serial port but unlike other cards, it uses just one port
for everything rather than a second port for information, signal strength
and the like.
