SMS SMPP Troubleshooting

SMPP Protocol is 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:

• https://en.wikipedia.org/wiki/Short_Message_Peer-to-Peer
• Protocol specification: https://www.openmarket.com/customer-center/documentation/SMSSMPP-Specification/SMPP-v3-4-Issue1-2.pdf

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
