A simple demo of SMS text messaging.

i can already send sms using my phone with at commands using C#, but i am having some difficulties receiving messages. i know that the way to do this is as shown above, but i do not know how to get the messages that the phone sends back to my app.

how do i program a “listener” to the phone to get the messages?

    I was going to be nice and give you some code snippets, but typing on the iPad isn’t great.
    So this website here probably explains is better anyway

    http://blogs.msmvps.com/coad/2005/03/23/serialport-rs-232-serial-com-port-in-c-net/

    There is a section there that shows setting up the DataReceived event to get triggered when you get data, rather than you having to poll the Read commands.

    I might also point out that while this will work for your phone, it may not work for others. Not all manufactures implemented their SMS AT commands the same… Which is frustrating. New phones don’t even bother with it at all 🙁
