This is very cool tech, but it seems like a niche use-case. It's not made for consumers, and the vast majority of IoT devices barely move, let alone between countries. But , if I were working for a haulage company and was interested in tracking, say, truck location, speed etc across the whole of Europe I could see this being a great way to do it.
Yet.
One of the things holding back the development of truly mobile IoT is ease and ubiquity of connectivity. This tries to solve that.
Think of it as Amazon's Whispernet, but with far more penetration.
