Send free SMS from your VB.NET application


This VB.NET code sends Email and SMS for free with the help of your Gmail ID. One main advantage of this is that you can send SMS for free because most webservices are not free to use with your application.

Using the Code

I used Gmail as my SMTP server and Mytoday to support free SMS Service here in this code. Since this code uses Gmail SMTP server, you need a Gmail account to send Email. Actually SMS from the application is sent from the Email. You can send SMS only to particular numbers in India. When you register your phone number in the website, an Email ID will be given for the phone number which you register, so that when you mail to that id the message will be received as SMS in the particular number. Suppose the phone number is 9897345890 the mail id given from that website will be like this It works only for Indian numbers.

To run this application successfully, two things should be done:

  1. You must have Gmail ID.
  2. Register the phone number which you are going to use in a website
Private Sub Button1_Click(ByVal sender As System.Object, _
	ByVal e As System.EventArgs) Handles Button1.Click

Dim smtpServer As New SmtpClient()
Dim mail As New MailMessage
smtpServer.Credentials = New Net.NetworkCredential_
	(TextBox1.Text & "", TextBox2.Text)
smtpServer.Port = 587
smtpServer.Host = ""
smtpServer.EnableSsl = True
mail.From = New MailAddress(TextBox1.Text & "")
If RadioButton1.Checked = True Then
mail.To.Add("91" & TextBox3.Text & "")
ElseIf RadioButton2.Checked = True Then
End If
mail.Subject = TextBox4.Text
mail.Body = TextBox5.Text()
MsgBox("mail is sent", MsgBoxStyle.OkOnly, "Report")
End Sub

Hope this code will be helpful...

It has been very long since i posted this, I dono whether it works or not. But let me tell what i did actually, Mostly no one provide free sms service api but the sites like 160by2 offer mail intimation services for free. have an account from way2sms, then you will be provided with an mail address for your mobile number. fill your sms contents in subject field of mail and send to mobile's mail address(**** should receive it as an sms.
