Well, it would be simple/small businessess mostly, and mostly taking the place of phone calling, for example asking for information, ordering something, "signing up" to receive offers/the daily menu... And that would be just a guy with a list and a phone forwarding and repplying messages and etc. Radio shows also use it to communicate with listeners(although it's kinda ridiculous that then they have to warn all the time not to text while driving)... So.. Yeah, mostly about communication, not about process.
