title: How do I program a mobile app to send SMS?
body: <p>I want a mobile app to send automated SMS. This will be in VB.Net. I've searched for articles on these but they are all about PC apps accessing a GSM modem or a mobile through a COM port. Is it the same process with mobile apps on the phone (not through a PC)? If yes, and I am to treat the GSM modem as a "port", how would I connect to it? If no, are there any useful resources for this?</p>
