I'm also having the problem of not being able to capture the packets of
the messages I send from this gateway.
When I tcmdump connections that have the IP of a SMSC, I can see the
submit_sm and deliver_sm packets without any trouble.
When I try to tcpdump a connection I have with the GSM Gateway, which is
connected via en Ethernet cable and has a SIM configured inside, I don't
see anything ressembling the message I'm sending. Is there anything I'm
missing?

I don't get it. Why do you say USB? My modem is connected via an
Ethenet cable, not USB. Maybe modem is not the best word for it. Is it
gateway? It's the Portech mv-374.

Hi
That is not possible if you use the GSM as a modem since it talks a
serial protocol (rs232/usb), not ethernet. You might need a
serial/usb sniffer.
wireshark/tcpdump does "sniff" TCP packets.

If you know a tcpdump would do, why don't you use it? On a linux
machine you would do: tcpdump -w FILENAME.pcap -s 0 host
XXX.XXX.XXX.XXX (for example) then use wireshark software to read
the resulting file from the capture.
Once on wireshark you can search for SMPP params, like phone number.
hope this helps.
