Uvalde County
400 Mbps Air Fiber. No contracts. No data caps. Local support you can actually reach.
As the gateway to the Frio Canyon, where the Hill Country begins and the cypress-lined Sabinal River draws visitors year-round, Sabinal is where South Texas meets the Hill Country on US-90.
With limited broadband infrastructure in Uvalde County, most residents are on Starlink or one of the older satellite options. STI's Air Fiber reaches Sabinal with 400 Mbps for $65/month — ground-based, storm-tested, and $65/month less than Starlink's 400 Mbps plan.
ZIP code served: 78881
Coverage note: Sabinal is at the western edge of our service area. Most in-town addresses in 78881 are covered; ranch properties, river camps, and county-road addresses vary the most. Call (830) 429-4149 with your address before assuming we can or can't reach you — we'll give you an honest answer.
Broadband infrastructure in Uvalde County has been limited — AT&T offers legacy DSL on copper lines at some Sabinal addresses, but fiber hasn't been extended to 78881, and other wired options are scarce. For most residents wanting real speeds, Starlink has been the primary option.
The Frio Canyon tourism economy — cabins, camps, and river access operations — has grown significantly, and many of those businesses need reliable internet for reservations, point-of-sale systems, and guest WiFi.
Sabinal began in 1854 as Hammer's Station, a stage stop on the Sabinal River, and sits about 20 miles west of Hondo on US-90.
Nearby: STI also serves Knippa 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.
