I have been through a few natural disasters here and this idea should be
as useless as boobies on a boar when the chips are down. Why?

The 2 major communications systems that collapse are #1 Cable (data/television) and #2 the cell phone network.
Last to go was the "old fashioned analog over wire" telephone system.

So sending everyone messages with a system that has caved in...ain't gonna fly.

Amazing stupidity....
