4G is generally available in rural areas?

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 $45 a month. This is being repeated quite a lot in rural areas with rural cooperatives.
Now coverage maps, AT$T says they have 3g but I get no service at my house, Sprint Map is spot on, and Verizon map I haven't compared.
