Hot Spot with your cell phone carrier. Be aware of data usage limits/costs. Then you can get a smart tv and at least steam stuff like netflix. I have Comcast and I can use any device to watch most live TV as long as I have an internet connection. So you can watch live TV from a tablet or even cell phone via your hot spot.
Can you do a hot spot with some kind of land phone service or something?
It can’t rely on the person and their cell phone. It has to be house specific.
