Answer 1

I have a perfect way to send SMS in visual basic, using AT-commands.
AT-commands:are instructed through which you can send and receive SMS messages, make calls from cell phone, and this is an example to Send a message:
Firstly:
Write this code in the top:
Imports System.IO.Ports
Imports System.IO
Secondly:
Write this code in the public class of form:
Dim SerialPort As New System.IO.Ports.SerialPort()
Dim CR As String
Thirdly:
Create a textBox(TextmsgTextBox) to write the text message, and TextBox2(MobileNumberTextBox) to enter the mobile number, and Button(SendBUT) to Send message.
And write this code in the button click event.
If SerialPort.IsOpen Then
SerialPort.Close()
End If
SerialPort.PortName = COM4
SerialPort.BaudRate = 9600
SerialPort.Parity = Parity.None
SerialPort.StopBits = StopBits.One
SerialPort.DataBits = 8
SerialPort.Handshake = Handshake.RequestToSend
SerialPort.DtrEnable = True
SerialPort.RtsEnable = True
SerialPort.NewLine = vbCrLf
Dim message As String
message = MsgRichTextBox.Text
SerialPort.Open()
If SerialPort.IsOpen() Then
SerialPort.Write("AT" & vbCrLf)
SerialPort.Write("AT+CMGF=1" & vbCrLf)
SerialPort.Write("AT+CMGS=" & Chr(34) & phoneNumBox.Text & Chr(34) & vbCrLf)
SerialPort.Write(message & Chr(26))
SentPicture.Visible = True
SentLabel.Visible = True
SentTimer.Start()
Else
MsgBox("Port not available")
End If
