Hi

Check this out for SMS API

By using that API we can send SMS which is recently I used

the Code in that API is detailed in API documentation

Here I'm providing sample code for that

The link to website is http://www.txtimpact.com/api.asp[^]

string ret=string.Empty;
 WebRequest w=WebRequest.Create("http://smsapi.Wire2Air.com/smsadmin/submitsm.aspx");
 w.Method="POST";
 w.ContentType="application/x-www-form-urlencoded";
  using(Stream writeStream = w.GetRequestStream())
      {
       UTF8Encoding encoding = new UTF8Encoding();
       byte[] bytes = encoding.GetBytes("VERSION=2.0&userid=[username]&password=[userpassword]&VASId=[VASId] & PROFILEID =[ PROFILEID ]& FROM =27126&TO=[Mobile Number]&Text=[Text Message]);
     writeStream.Write(bytes, 0, bytes.Length);
      }
   using (HttpWebResponse r = (HttpWebResponse) w.GetResponse())
        {
       using (Stream responseStream = r.GetResponseStream())
          {
           using (StreamReader readStream = new StreamReader (responseStream, Encoding.UTF8))
              {
              ret = readStream.ReadToEnd();
              }
          }
         }
    MessageBox.Show(ret); /* result of API call*/

All the Best
