Using your contact form to send a text message is pretty easy. All you need to know is who your carrier is and the phone number. You would use these examples in form as the email addresses. There are some limitations though, header information that is sent along with a typical email address can present a problem. Test this system out first by sending a simple email to the mobile number you want to use. In general the type of message you are creating is a multimedia message. If all is well then your good to go!
