Just Google "Internet SMS Gateway" and choose one provider, which has .NET based API.

you can send sms web to mobile using serial port communication via gsm modem and code in given below.

C#

           sendsms sms = new sendsms(); // create object for class
            sms.mysms(txtmobnum.Text, TXTMSG.Text);


//send sms class

SerialPort SMSPort = new SerialPort(COM5, 9600, Parity.None, 8, StopBits.One);
    public void mysms(string mobile,string message)
    {
        string SerialIn = null;
        byte[] RXBuffer = new byte[SMSPort.ReadBufferSize + 1];

        if (!SMSPort.IsOpen)
        {
            SMSPort.Open();
            SMSPort.WriteLine(&quot;AT+CMGF=&quot; + &quot;1&quot; + (char)(13));
            SMSPort.Read(RXBuffer, 0, SMSPort.ReadBufferSize);
            SerialIn = SerialIn + System.Text.Encoding.ASCII.GetString(RXBuffer);

            SMSPort.Write(&quot;AT+CMGS=&quot; + &quot;\&quot;91&quot; + mobile + &quot;\&quot;&quot; + System.Environment.NewLine);
            SMSPort.Read(RXBuffer, 0, SMSPort.ReadBufferSize);
            SerialIn = SerialIn + System.Text.Encoding.ASCII.GetString(RXBuffer);

            SMSPort.Write(message+ (char)(26));
            SMSPort.Read(RXBuffer, 0, SMSPort.ReadBufferSize);
            SerialIn = SerialIn + System.Text.Encoding.ASCII.GetString(RXBuffer);
            SMSPort.Close();

        }
    }
