A satellite phone or shortwave amateur radio can be used for low bit rate transmissions. 

I posted a list of mesh network options to the list 10 August, when we were discussing Kashmir. These types of solutions operate at WiFi rates, but the units can’t be too far from each other. Normal phones are limited to 10 meters, but special antennas allow about 50 kilometer line-of-sight communication. When there is widespread resistance, a mesh network can be created from thousands of phones and a signal can propagate from one to the next, as long as there is no wide gap. 

One way to ensure no gaps is to pay people, with crypto-currency, to be in the right place. Bitcoin can be transmitted by shortwave radio or into an area by satellite:

I discuss a comprehensive approach to mass direct action using mesh networking here (sub list for access):
