We aren't full timers or anything like that. We travel, maybe 5 times a year for anywhere from a week to 4 at a time.
We found that ATT hotspot data plan works bests for us. I think it was $35 a month for 25gb of data which is great for us. We do not stream. Renew as we need it and only charged for the month we use it.
Tried Verizon but it would not hold a signal on the road. AND they charged $35 to connect it each time you start the plan.
We are are on cheapo phone plans with next to no data service.
