Doing something similar here in MI due to high price of Comcast/Xfinity internet.
Got a prepaid phone with Verizon. $30/mo with 500k of data (cheapest option)
Added a prepaid wifi spot 4G LTE with unlimited data and streaming. When combined with prepaid phone and autopay it costs $45/mo. Since my wife can take it anywhere with her, she now has unlimited data on her $30 phone. And unlimited streaming on phones tablets and smart TV.
Since verizon has good service all over, we can use the hotspot on vacation or even if we move. Seems like the best deal I can find now given that there are no phone/cable based service providers in my area that can do internet for less than $80/mo.
