Short Message Peer-to-Peer (SMPP) is an open, industry-standard protocol that the telecommunications industry uses to exchange SMS messages between Short Message Service Centers (SMSC) and/or External Short Messaging Entities (ESME).
Our SMPP documentation assumes that you already have a basic understanding of the SMPP protocol and know how to set up your own SMPP client software..
SMPP access is not enabled by default on accounts. Please email us your request along with a monthly volume forecast and we will gladly assist by providing you with your SMPP username (system_id) and password.
SMSPortal supports the industry standard SMPP v3.4 protocol.
Versions 3.3 and 5.0 are not supported.
