SMPP Client is a browser-based SMPP v3.x and v5 client that can be used for testing and development. It supports SMPP SubmitSM, DataSM, QuerySM, CancelSM and EnquireLink PDUs.

Enter the SMPP server / SMS Gateway / SMSC hostname (e.g. SSG Customer endpoints), port system ID and password to connect an SMPP session from your browser. Once connected, you can perform a number of SMPP operations. A log shows all activity taking place during the SMPP session.
