I attempted this when I got an apartment out in western Maryland. We have t-mobile, with unlimited everything, including hotspot, and the plan was just to use the hotspot to connect to the smart tv for Netflix, Hulu, and Amazon Prime Video.

Problem was/is, that the service out where our apartment is isn’t very good. It’s serviceable, but slow. I also looked into repeaters, but they’re all really crappy when you read the fine print. They don’t do anything to help speed, and often, they introduce so much latency, it’s not really worth it. We’ve just been living with it, because we refuse to get fleeced by the single internet and cable provider that out there.
