The SMPP protocol allows a client’s applications to access World-Text’s Mobile Message Routing Platform (MMRP) to send and/or receive SMS.

The application should implement the SMPP protocol (version 3.3 or 3.4) to communicate with World-Text’s systems. SMPP SDK and toolkits are available from a number of sources for Java, C/C++, Perl, VB and other languages on various operating systems. One such SDK is the SMPP Developers Toolkit and is available from Logica CMG.

Further information on this toolkit is available from Logica CMG Other toolkits and SMPP capable applications are available from 3rd party vendors.

We have an SMSC simulator running on our servers, this provides full FREE access to our SMPP interface for testing and integration. If you would like to verify your application against our simulator simply drop us a line and we will send you the connection details required.

Please note, the simulator is NOT a protocol verifier, neither does it deliver messages. It simply responds appropriately to the SMPP commands that our service supports.

For a protocol verifier we suggest WireShark.

The SMPP link tester is a simple SMPP Windows 2000/XP/Vista application that test basic TRX bind and issues and responds to enquire link packets. It is designed to verify that you can correctly bind to World-Text or any other SMPP v3.4 service provider.
