Frio County
400 Mbps Air Fiber. No contracts. No data caps. Local support you can actually reach.
As the Watermelon Capital of the World, Dilley's agricultural economy runs on precision and timing — and so does its workforce, which depends on reliable internet for everything from harvest logistics to running a business along I-35.
Most residents here are on Starlink or older satellite options. STI brings 400 Mbps Air Fiber to Dilley for $65/month — reliable, ground-based, and half the price of Starlink's 400 Mbps plan. The connection this hardworking Frio County community deserves.
ZIP code served: 78017
Coverage note: Most addresses in 78017 are within our service area. Farm and ranch addresses on rural Frio County roads vary with distance from our nearest tower — call (830) 429-4149 before signing up and we'll give you a straight answer.
Dilley is Frio County's largest community on the I-35 corridor, but broadband here is limited: AT&T offers DSL on older copper lines, fiber hasn't been extended to 78017, and cable options are thin. For residents and businesses wanting real speeds, Starlink has been the most common solution.
Watermelons put Dilley on the map, and the farms and packing operations around town depend on connectivity for logistics and communication during harvest. Dilley families also have the same remote work, online schooling, and streaming demands as anywhere else — and they've been paying satellite prices for it.
At about 47 miles from our Hondo office, Dilley is one of the farthest points we serve — and it gets the same 400 Mbps, $65/month plan as the rest of our footprint.
Nearby: STI also serves Moore 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.
