        SMS.MashapeKey = "<xxxx>";
        SMS.Username = txtNumber.Text.Trim();

        if (txtRecipientNumber.Text.Trim().IndexOf(",") == -1)
        {
            //Single SMS
            SMS.SendSms(txtRecipientNumber.Text.Trim(), txtMessage.Text.Trim());
        }
        else
        {
            //Multiple SMS
            List<string> numbers = txtRecipientNumber.Text.Trim().Split(',').ToList();
            SMS.SendSms(numbers, txtMessage.Text.Trim());
        }

I believe that error means you username/password or something not in the code is incorrect.

Hello,
my first guess is, that the web server might check the request's User Agent.
So try something like this:

C#

HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create("http://ubaid.tk/sms/sms.aspx?uid=" + uid + "&pwd=" + password + "&msg=" + message + "&phone=" + no + "&provider=fullonsms");
            //see for other choices: http://www.useragentstring.com/pages/useragentstring.php
            myReq.UserAgent = "Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2049.0 Safari/537.36";
            HttpWebResponse myResp ...

On the other hand, I've just tried to check this website (I didn't know about it) and it says it's under maintenance, so maybe that's the real cause.
