What phone do you have? If it's a new phone that support band 12 (700 mhz), your semi-rural area may have perfect LTE coverage now. My grandparents just got a new phone and they have data coverage for the first time ever, but I'm on an iPhone 6 that doesn't support band 12, so I don't get data when I'm there.
I'm actually permanently roaming on Iowa Wireless but keeping my T-Mobile account from when I lived elsewhere. I do have LTE right now at work, but visiting the in-laws 15 miles away quickly turns it into a 2g or 0 signal scenario.
