I worked in telco in Indonesia where this type of thing is taken to the next level. Back in the day you would walk into a rooms filled with racks full of phones for SMS / Airtime sales "optimisation". I tried to google some pictures now but it turns out Im behind the times. They've gotten rid of the phone part completely! [0] Now you just buy the sim cards and let modems do the rest..
