What is an SMPP Gateway?
SMPP is considered the industry standard for sending SMS to Network providers and is our native protocol. 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). ClickSend offers a powerful high throughput SMPP gateway, supporting the industry standard SMPP v3.4 protocol.
