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 at $120/month or one of the older satellite options. STI's Air Fiber reaches Sabinal with 400 Mbps for $65/month — ground-based, storm-tested, and $55/month less than Starlink.

Sabinal is in Uvalde County along US-90, at the point where the terrain transitions from South Texas brush into the beginning of the Hill Country. Broadband infrastructure in Uvalde County has been limited — AT&T offers legacy DSL on copper lines in some Sabinal addresses, but fiber has not been extended to 78881. Spectrum does not serve this area. For most Sabinal residents wanting real speeds, Starlink at $120/month has been the primary option.
Sabinal's position as the gateway to the Frio Canyon and the cypress-lined Sabinal River means it draws a mix of permanent residents, retirees, and vacation property owners. 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. Starlink works for some, but the latency and weather sensitivity are real limitations for business-grade use.
STI's coverage reaches into Uvalde County from our South Texas tower network. Sabinal is at the western edge of our service area, and coverage in 78881 is available for most community addresses. Because this is further from our Medina County operations base, it's worth calling to confirm your specific address is within coverage before scheduling.
Rural addresses outside Sabinal — ranch properties, river camps, and county road addresses — have the most variable coverage in this zip code. Call (830) 429-4149 with your address before assuming we can or can't reach you. We'll check and give you an honest answer on what's available at your location.
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.
