Public Class Form1
    'connect your mobile/GSM modem to PC,
    'then go in device manager and check under ports which COM port has been slected
    'if say com1 is there then put com2 in following statement
    Dim SMSEngine As New SMSCOMMS("COM7")
    Dim i As Integer
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

            SMSPort.Close()
        End If
    End Function

    Public Sub Open()
        If Not (SMSPort.IsOpen = True) Then
            SMSPort.Open()
        End If
    End Sub

        If SMSPort.IsOpen = True Then
            SMSPort.Close()
        End If
    End Sub
End Class

Please explain this portion of your code

Public Function ReadSMS() As Boolean
If SMSPort.IsOpen = True Then
'reading AT commands
SMSPort.WriteLine("AT")
SMSPort.WriteLine("AT+CMGF=1" & vbCrLf) 'set command message format to text mode(1)
SMSPort.WriteLine("AT+CMGL=ALL") 'set service center address (which varies for service providers (idea, airtel))
'SMSPort.WriteLine("AT+CMGS= + TextBox1.text + " & vbCrLf) ' enter the mobile number whom you want to send the SMS
'_ContSMS = False
'SMSPort.WriteLine("+ TextBox1.text +" & vbCrLf & Chr(26)) 'SMS sending
MessageBox.Show(":read")
SMSPort.Close()
End If
End Function

A msg displays as message sent but i dont seem to get where its being sent to
