SMPP Hub

SMPP is a highly scalable Store and Forward Platform for Operators & SMS Aggregators. For better performance, it is architected to make a First delivery attempt and undelivered message are stored and retried.
The architecture provides high performance throughput per Server and provides seamless scalability both vertically and horizantly. This API can be used to send all kinds of SMS types, including ordinary text, binary, and Unicode messages, You can also download SMPP account delivery report.
The Short Message Peer-to-Peer (SMPP) is a protocol used by the telecommunications industry for exchanging SMS messages between Short Message Service Centers (SMSC) and/or External Short Messaging Entities (ESME).
The protocol is a level-7 TCP/IP protocol, which allows fast delivery of SMS messages.
The most commonly used versions of SMPP are v3.3, the most widely supported standard, and v3.4, which adds transceiver support (single connections that can send and receive messages). Data exchange may be synchronous, where each peer must wait for a response for each PDU being sent, and asynchronous, where multiple requests can be issued in one go and acknowledged in a skew order by the other peer.
