Just as an anecdote / FYI, since I had an LLC registered, I signed up for Teltik which uses T-Mobile and got a 5MB/month hotspot plan through them. Got my dad a nice LTE hotspot (https://www.amazon.com/gp/product/B01N5ASNTE/) and that's what he uses for his home internet. Obviously his usage is modest - no streaming media (Netflix, etc.), but some YouTube. However, it is so much better than the previous FreedomPop / DataJack stuff we used before, although those were dirt, dirt cheap.
I ran a quick Speed Test check on his connection, and got 29 Mb/s down and 15 Mb/s up. https://www.speedtest.net/result/7621011424 (about 14 months ago.) Obviously this will vary by location!
When I had Comcast, I believe it showed me monthly usage, and I think it was something like 20 GB per month. That's with heavy Netflix/Hulu usage every evening. This wireless internet would probably work for us speedwise... but because I live somewhere that offers both Comcast and Verizon FIOS, I'm able to get 100/100 Mbps service for $40/month. And that's a wire into my home and no concern over hidden data caps (at my usage levels). I wouldn't choose wireless over that unless there was significant savings.
