I'm on a Hughes VSAT as we "speak". It's overpriced and incredibly low bandwidth, and a hellish company to deal with for customer service, but it's our only option and we've been using it for over 10 years.
BTW, I'm not using wifi though, I'm using a wire. We find that using the wifi router makes the Hughes bandwidth even slower, and I'm afraid that everyone's random phones and other devices will update their whole software all night and use up the teeny monthly quota. So we hid the wifi router in the cupboard and only use the cable. What we need is internet, not necessarily wifi, and it might help to clarify your search. For example, in our town office we've got wifi but the "broadband" internet is usually down, so in town we've usually got wifi but no internet, and that's useless. At our school campus we've got internet but not wifi, and that's useful. Of course both together would be ideal, but that's not available at this time.

Where I live there is no cell phone coverage so we use one of those boosters. AT & T told me there is an option for about $25.00 more for something that plugs into an electrical outlet that "Boosts' their service to make it like a land line, their words not mine.
For internet we have Hughesnet. I would suggest asking a service provider in the nearest local town what your options are. Might be Wild Blue if you are not on Hughesnet's coverage area.
