OP:
As you'll note there are many and varying ideas all of which have merit. Unfortunately mobile Internet is not a one size fits all or all locations. Many of us rely on an arsenal or the Swiss army knife approach.
https://www.rvmobileinternet.com/ is a good site to familiarize yourself with some of the terms, components, providers, available options. It's cutting edge info. (crib notes) plus Moore's law is holding true, everything in technology is changing rapidly, and you can throw a bunch of money at it.
Best of luck
