I think you need to use a webservice like

What is the response message you get for this HTTP post ?

You are missing this code

webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.Method = "POST";
webRequest.Timeout = 5000;

webRequest.ContentLength = bytes.Length;

Use this code

C#

HttpWebRequest webRequest = null;
string response = "";
byte[] bytes = Encoding.UTF8.GetBytes(xml);

try
{
    webRequest = (HttpWebRequest)WebRequest.Create("http://api.fastalerts.in/fastclient/SMSclient.php?username=" + senderusername + "&password=" + senderpwd + "&message=" + msg + "&numbers=" + phonenumber + "&senderid=" + senderid;);
    webRequest.ContentType = "application/x-www-form-urlencoded";
    webRequest.Method = "POST";
    webRequest.Timeout = 5000;

    webRequest.ContentLength = bytes.Length;
    using (Stream requeststream = webRequest.GetRequestStream())
    {
        requeststream.Write(bytes, 0, bytes.Length);
        requeststream.Close();
    }

    using (HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse())
    {
        using (StreamReader sr = new StreamReader(webResponse.GetResponseStream()))
        {
            response = sr.ReadToEnd().Trim();
            sr.Close();
        }
        webResponse.Close();
    }
}
catch(Exception ex)
{
    
}
return response;
