We do not full time, but I am able to work from the road for several weeks at a time. I run my own software business and when traveling I only need internet and phone service through cellular. I have a grandfathered AT&T unlimited plan and I currently use a Netgear hotspot that is on my unlimited plan. I have added an external MIMO antenna that usually gives me a good signal in most every place we've been. I never bother with campground WiFi even when it's available. It's certainly not the Gig speed internet I get in my office through Comcast, but it suffices for my needs and we can stream television, use Alexa for music, etc.
All total, I maybe have $350.00 in equipment for the connectivity and the hotspot is like having another phone on my plan which for me only adds about $20.00 per month. You could easily get multiple failover plans and equipment and spend thousands to get a mobile office, but do you really need that? I do not.
