Frio County
400 Mbps Air Fiber. No contracts. No data caps. Local support you can actually reach.
Moore is a Frio County community on I-35 and US-81, about 13 miles northeast of Pearsall, with roots in ranching and the old railroad wool trade.
Being right on the interstate hasn't brought fiber to 78057, and many Moore households and surrounding ranches rely on satellite. STI's Air Fiber is 400 Mbps down / 25 Mbps up for $65/month — ground-based, no contract, no data caps.
ZIP code served: 78057
Coverage note: Most addresses in and around Moore are in range. The 78057 ZIP covers a wide stretch of Frio County, so ranch and county-road addresses at the edges should call (830) 429-4149 to confirm.
Around 1910, Moore was reportedly one of the larger towns between Laredo and San Antonio, built on artesian-irrigated cotton before the local economy shifted to ranching.
Nearby: STI also serves Dilley on the same $65/month plan.
When something goes wrong, you call (830) 429-4149 — and you talk to someone who lives and works in South Texas. Not a ticket system. Not an overseas call center. And new customers are installed within one business day.
