[VB.NET] Send a text message to a Cell phone

Well oddly enough when you text a cell phone it's like emailing someone, in a sense that it actually uses an email address.

This is some sample code from my SMS spammer I made a long time back:

To get this started you need to do some imports at the top of your form or class:

Code:

---

Imports System.Net.Mail
Imports System.Net
Imports System.Diagnostics

---

Then the code for sending the email:

Code:

---

Dim smtp As SmtpClient = Nothing
        Dim sms_message As New MailMessage()
 sms_message.From = New MailAddress(My.Settings.email)
                sms_message.To.Add(txt_number.Text & provider)
                sms_message.Subject = txt_subject.Text
                sms_message.Body = txt_message.Text
                smtp = New SmtpClient("smtp.gmail.com")
                smtp.Port = 587
                smtp.EnableSsl = True
                ' Edit email address  and password accorindingly. You don't need to have @gmail.com
                smtp.Credentials = DirectCast(New NetworkCredential(My.Settings.user_name, My.Settings.password), ICredentialsByHost)
                smtp.Send(sms_message)
                ProgressBar1.PerformStep()

---

Now this was a chunk of code taken from the actual program and sitting as it wont work correctly.

Somethings that need to be changed:

Code:

---

smtp.Credentials = DirectCast(New NetworkCredential(My.Settings.user_name, My.Settings.password), ICredentialsByHost)

---

My.settings.user_name and My.settings.password , My.setttings.email

You can just Dim 3 variables as string and sub those in.

Code:

---

sms_message.To.Add(txt_number.Text & provider)

---

Provider is the cell phone carrier and txt_number is well their cell number.

I'll be nice and also include the sms addresses.

You can ignore the case statements and just pull the address's from it

Code:

            Select Case cmb_phone_services.SelectedIndex
                Case 0
