Cuba does this to some extent, though I don't think it's internet connected. They do share contraband media smuggled in on SD cards.
I mean, ~~carrier pigeons~~ sd cards or thumb drives being moved by motorbike is actually a reasonable way to move a lot of data, in one chunk, fairly fast, in poor infrastructure environments, given how insanely space dense storage memory is now... but yeah thats not gonna work for lots of little bits of data moving to many places, very fast.
Thats what 4G, 5G, other radio frequencies that work well enough for data transfer are for.
Like, I am posting this from a phone that is WiFi connected to a 5G base station tower, because my building is too shit to even have a working cable line.
120 mbs down, not blazing fast, but more than enough to stream 720p/1080p 60fps video, latency is actually low enough to stand a chance at an online competetive game.
FCC regulations not withstanding... you could concievably just jerry rig this thing to directly talk with other same base stations, instead of or as well as the tower its actually connected to.
If there aren't already people out there somewhere making rough analogues to a 5G internet base station, that can talk to each other as basically dedicated local mesh routers... out of rasberry pi's or something... I'd be shocked.
Fuck, you could blast a HAM or CB radio with 56k dialup protocol, and some kind of extra redundancy/signal noise processor.
Again, laws against this notwithstanding... thats absolutely possible to do.
