SMPP

SMPP is a protocol designed to describe the communication between a client and SMS server on the platform and transfer SMS and USSD messages.

Client session modes

  • Receiver (client <- server). This mode will let you receive commands from the server but will not let you send commands to it.
  • Transmitter (client -> server). This mode will let you send commands to the server but will not let you receive commands from it.
  • Transceiver (client <-> server). As a universal communication mode, it will let you both send and receive commands.
