Answer 1

You have to send to the SMS gateway. It is provider specific.

Wikipedia has a List of SMS Gateways.

For example, to send to a Sprint PCS number you would send to number@messaging.sprintpcs.com, where number is the phone number (i.e. 5551234567, or whatever).

Answer 2

For those who have looked so much for a free way to send SMS from a web app, and are in France, and having FreeMobile as operator, I've just found a way in calling a free web service provided by FreeMobile. I've written this code in C# and it works fine.

private void SendSMSAlert(String message)
{
    try
    {
        String url = "https://smsapi.free-mobile.fr/sendmsg?user="YourFreeMobileIdentifierHere"&pass="YOURPASSHERE"&msg=" + message;
        var request = (HttpWebRequest)WebRequest.Create(url);
        HttpWebResponse response = (HttpWebResponse)request.GetResponse();
        response.Close();
    }
    catch(WebException e)
    {
        System.Diagnostics.Trace.WriteLine("SMS Not Sent! Exception "+e.ToString());
    }

}

So if you have a freeMobile line in France, you can get your Pass from https://mobile.free.fr/moncompte/

Then, if you need to forward the SMS to other numbers, it can be done with many mobile apps on AppStore or GooglePlay.

I hope this helps!
