SMPP Messaging API

For SMS Integration

SMS integration using SMPP Protocol

Short Message Peer to Peer (SMPP) is an open industry standard messaging protocol used to connect directly to a SMSC (short message service centre). SMPP is ideal if you want a simple and quick way to send large volume SMS messages to UK and international GSM phones.

It’s reliable, efficient and secure, with 2-way messaging capability and comprehensive message delivery reporting. In addition, on request, intermediary delivery receipts can be provided, showing almost instantaneous acknowledgement of whether messages have been accepted or rejected by the Network Operator.
