Yes; Verizon has an offering designed explicitly for rural areas[1], but it's expensive. The linked article is from 2012, and prices have since declined, but the general gist of the service is the same: a big antenna you bolt to your house or a tree and will pull from an existing account-level share plan (if you have one).
People will have better luck with rural telephone companies trying to stay alive then big wireless carriers. Sprint and T-Mobile absolutely suck in coverage area for rural folks.
One example, Steele ND and the surrounding area is served by a small rural telephone company that is laying a lot of fibre (I'm hoping they head North). A 200M plan (no cap) for $45 a month. This is being repeated quite a lot in rural areas with rural cooperatives.
I usually think of where I live as rural due to the distance to a major city (20 miles to Athens, GA), but I do get occasional 4G inside the grocery store. It's more exurban than rural.
The last time I lived in a deep rural area (Norton, KS) there wasn't a good cell option. The cell tower that covered the town was flaky at best in terms of reception. So, I guess your mileage may vary applies in that situation?
If Verizon is trying to expand their wireless offerings into areas where dial-up is currently the only option, then having much more direct marketing access to those dial-up users sounds pretty useful for them.
