I used an AT&T Mobley on my summer stay in Alaska. It's like the Verizon option, unlimited data but prioritized after 22GB. Got an HDMI FireTV Stick that connects to the Mobley via WiFI and signed up for a DirecTV Now account. It all worked fine with very few glitches in streaming even when I was way over my 22GB for the month. The Mobley costs $20/mo and the DirecTV Now was another $20.
At the S&B I have a DishTV setup (switched from DirecTV a few years ago). Dish has something they call DishAnywhere which, with the proper setup at home, allows you to sling all your Dish stations over the internet for no additional cost where they can be picked up on a FireTV Stick, Roku, Apple TV, etc. It's on my ToDo list to get it set up at home before my next trip as my basic Dish channel lineup is more than I was able to get on DirecTV Now. Plus it appears it will give me my home/local TV stations while on the road.
