SMPP Protocol are binary encoded for efficiency. It is not text based as SIP protocol so packet capture with tethereal to .pcap file will not show human-readable information.

Must-read before proceeding:



pcap file capture



pcap file view over Wireshark



Manually sending SMS from command line

If we have something else but not [ESME_ROK], then check error code from this file for the cause: File:Smpp error codes.pdf
