I am using the following script for sending sms through our website, but it does not work. The sms is not sent. So can anyone help me to solve this problem?

Label sms = new Label();
       sms.Text = "Your Login Id is " + user_id + " and password is " + pass;
       string strUrl = "http://www.way2sms.com?user=user_id:pass&senderID=e&receipientno=9001233211&msgtxt= " + sms  ;
       WebRequest request = HttpWebRequest.Create(strUrl);
       HttpWebResponse response = (HttpWebResponse)request.GetResponse();
       Stream s = (Stream)response.GetResponseStream();
       StreamReader readStream = new StreamReader(s);
       string dataString = readStream.ReadToEnd();
       response.Close();
       s.Close();
       readStream.Close();
       dbcon.closecon();
        try
       {
           //Create the request and send data to Ozeki NG SMS Gateway Server by HTTP connection
           HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(strUrl);
           //Get response from Ozeki NG SMS Gateway Server and read the answer
           HttpWebResponse myResp = (HttpWebResponse)myReq.GetResponse();
           System.IO.StreamReader respStreamReader = new System.IO.StreamReader(myResp.GetResponseStream());
           string responseString = respStreamReader.ReadToEnd();
           respStreamReader.Close();
           myResp.Close();
           //inform the user
           //lblMessage.Visible = true;
           //lblMessage.Text = "Sent Successfully";
           //textboxError.Visible = true;
       }
       catch (Exception ex)
       {
           //if sending request or getting response is not successful, Ozeki NG - SMS Gateway Server may not be running
           //lblMessage.Visible = true;
           //lblMessage.Text = " SMS Gateway Server is not running!" + "<br/>" + createdURL + ex.Message;
           //textboxError.Visible = true;
       }
