Looks like if you can get 56Kbps or more with HAM you can do IP: https://www.scc-ares-races.org/data/access/tcpip-uhf/tcpip-uhf-access.html
So if you have independent electric power and can run a HAM radio you can get basic internet access. Probably not enough bandwidth to run a good VPN but at least you could encrypt emails/SMS.
I think in any situation needing this kind of thing it will be important to have people outside the geographic area but within "friendly" territory to send messages to. That person's job will be to copy information to social media so news gets out about what's going on. So far the news (Fox included) aren't even reporting what's happening in VA so I would expect similar/worse. This person should be able to use TOR and post to 8Kun as that seems to be the only place not yet interfered with, and most internet news seems to start there and then spread to other places. 4chan is compromised, we saw that with the guy in NY and also with the "Kingdom of Xi" or whatever it was threads getting shut down.
There should also be more than one of this person, ideally I'd want about ten different people to try in case anyone is targeted. Ideally, no one in the pool should know who else is in that pool, for the same reason.
