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 at $120/month or older satellite options. STI brings 400 Mbps Air Fiber to Dilley for $65/month — reliable, ground-based, and half the price of Starlink. The connection this hardworking Frio County community deserves.
Zip codes served: 78017
Dilley is Frio County's largest community on the I-35 corridor, and despite that position on a major interstate, broadband infrastructure here is limited. AT&T offers DSL service in Dilley on older copper lines, but fiber has not been extended to 78017. Spectrum does not serve Dilley. For residents and businesses wanting real speeds, Starlink at $120/month has been the most common solution.
Agriculture drives Dilley — watermelons are the crop that put it on the map, and the farms and packing operations around town depend on connectivity for logistics, inventory, and communication during harvest season. But internet needs here go well beyond agriculture: Dilley families have the same remote work, online schooling, and streaming demands as any community, and they've been paying satellite prices for it.
I-35 visibility gives Dilley more exposure to passing traffic than most small towns in our service area, and that's brought growth — new residents and small businesses that need reliable connectivity from day one. STI covers Dilley from our Frio County network, and most addresses in the 78017 zip code are within our service area.
If your address is outside Dilley proper on a rural Frio County route, call before signing up. Farm and ranch addresses on county roads can vary in coverage depending on distance from our nearest tower, and we'll give you a straight answer on whether we can serve your location.
