I'm not OP, but my parents house in Missouri sits around $300/mo for internet via mobile hotpot, occasionally getting up to around $500/mo in the months were a lot of family visit. HughesNet is their only available ISP, so they just went with a data plan through either AT&T or T-Mobile ("unlimited" but with a data cap with expensive overages that also drop you down to dialup-esque speeds) and stick that SIM card in their router. There was also a brief stint of time when I lived in Europe in a long-term Airbnb that didn't tell us there was a data cap (and since we weren't real residents, we couldn't set up our own internet) and I got nearly $500/mo for a few months doing video calls for work etc from my LTE.
