I have not yet seen someone try to replicate this in the US yet, but there are definitely options like broadcasting via satellite and radio waves to LN node operators to keep your bitcoin network connections even if your internet provider cuts you off

Yeah, I think the system they use for feature phones is different in Africa, so this will work.
Ive been thinking about this more bc of state of the world or censorship. With the setup your talking about, I guess you still need a satellite connection, electricity for PC, and a mesh device, and a close node.
