How do I send SMS directly via SMPP? My provider provides an SMPP interface to send SMS, how do I connect it to it? Are there any libraries or examples that can educate me on using SMPP to send? Perhaps using PHP? or C#?
There's the Logica SMPP project, written in Java, that could educate you on the matter. Other than that, there's a list of projects on the SMPP Wikipedia page that could fill a similar purpose.
