Looking at the coverage map for your area, AT&T has much better coverage. If you don't mind forgoing LTE capability, using an AT&T MVNO is your best bet. Net10 has unlimited minutes, unlimited texting, and roughly 1.5GB of data for $50 a month ($45 a month if you sign up for automatic credit card renewal). T-Mobile has okay coverage in your area, and if you want to get on the $30 dollar plan for 100 minutes, unlimited texting and unlimited data (throttled at 5GB). Straight talk also offers AT&T coverage, but they've stopped selling AT&T sim cards. So to get one, you'll have to buy it online from ebay or similar websites where they're going for quite a pretty penny. They will honor it though if you get one and they offer the same package as Net10.
