How can I use the Short Message Peer-to-Peer (SMPP) network protocol?

Short Message Peer-to-Peer (SMPP) is a 'low level' network protocol used to send and receive SMS traffic between various parties. SMPP is especially popular among heavy users of SMS, including aggregators and operators.

The most commonly used versions of the protocol are v3.3 and v3.4. Often the TCP port 2775 is used for SMPP. The SMPP protocol is no longer being developed. An alternative to SMPP is EMI but MessageBird doesn't support this protocol currently.

Are you planning to use the SMPP protocol but you don’t support this technology yet? We recommend the open source software Kannel which runs on Linux.

If you are interested in a MessageBird SMPP account, feel free to contact our Sales team at
