While I too have the vague feeling that there's a lot of unrealized potential in SMS I must admit that apart from appointment reminders and alerts I can hardly think of any (first world) business use case where SMS-first actually does make sense. Even most real-world Twilio examples mostly seem to be along the lines of rather frivolous applications such as BeerText.Us, which is great but hardly stuff you can build a business upon.
