Maybe 3G notification if the machine is borked? Alternatively, if a company operates for decades, they can make a very, very stable product. Only bugfixes. I'd imagine some of these vending machines are manufactured like that. Which means, a weekly drive by is enough to inspect, refill, drive on. I used to deliver meats to very rural locations, 10 deliveries over a 300+ km circular route from/back to the packing plant. At 80km/hr, the stops are the big slowdown. Another way to think of it, is that remote often means little traffic, fewer stop signs, and higher speed limits. I live 8km from a large city. It's often far faster for me to drive 15km to a corner store in a small nearby town, because I can do 120km/hr the whole way there almost, on my rural road, with no stop signs or lights. Drive to the city, there are 5 stop lights before the first corner store, that's each way, so chances are high to hit a light. And even one light is 2 or 3 minutes delay. So rural servicing and deliveries can be quite fast and efficient.
