Well then, it sounds like the traditional choices of a) satellite, b) Cable, and c) ADSL over telephone.
The real problem will be whether or not you can turn it on and off at will. If it has to be available year round, or if the companies you deal with require either year-long contracts (some cell companies) or have turn-on/turn-off fees (like Comcast Cable), that will figure into your cost calculation.
Exactly, the idea that we have to pay services for a full year is the pricy part.
There is phone service up there. And the last time I was up there, for the first time, I could make cell calls and texts with ATT which didn’t used to work at all.
