Those are key pieces of information, thanks. I wonder how the existing LoRAWAN based mesh networks work for text messaging. Anyways intermittent text messages itself would go a long way for those who are totally unconnected from the rest of the world, say to know whether the child opened their educational device[1] or say SOS from that device.

Yes, I think it's a very exciting technology for sending all kinds of small packeted data around rural areas. Besides messaging, it's also good for having remote stations report their current conditions (e.g. electric fence battery, solar panel status, soil moisture, weather conditions, etc)

There are already several companies producing turn-key agricultural monitoring systems like that. But I also think that a big part of why it works well is the lack of congestion in more remote areas.
