Jamaa SMPP Client is a .NET implementation of the SMPP protocol that focuses on providing an easy-to-use and robust SMPP client library for .NET developers. This project is intended to be used by developers who want to integrate SMS functionalities in their applications as well as students who are learning the SMPP protocol.
For Sending it's already supported.
For Receiving We can not do that because it's needed to store the previous parts.
You need to implement your code. That is what I'm doing on client_MessageReceived:
Can you paste an example of concatenated SMS? because I'm receiving 2 or 3 separated messages.
