There are several comments here noting that small towns are pretty well wired. I’m fortunate to have just purchased a vacation home in rural Wisconsin (close to family). In DC, I have 100Mbps fiber, a free upgrade from FiOS from the 25Mbps I ordered, with the option to get a gigabit. At my other house, I have a 6Mbps DSL that only delivers 1.5Mbps at best, with a couple hundred Kbps upload. There’s a cell tower only…
If the tower you are able to hit with 2 bars is AT&T, buy a used/refurbished MR1100 cellular router for less than $150 from Ebay, buy a high gain 4G MIMO antenna and cables for about $100 (try to learn what frequency your tower is on first), and pay $50 a month for an unlimited AT&T data sim (I've used this guy: https://www.ebay.com/itm/4G-LTE-ATT-Unlimited-HOTSPOT-Data-5...).
If your closest tower is not AT&T, there's probably something comparable. There's probably not a great price advantage to the SIM card resellers, but they do make it easier to try things out. I'm currently using an excellent local provider instead of AT&T (VTelWireless), and a speed test just confirmed I'm at a delightfully usable 50/25 Mbit/s.
