Medina County
400 Mbps Air Fiber. No contracts. No data caps. Local support you can actually reach.
D'Hanis is a small Medina County town on US-90 just west of Hondo, known for the D'Hanis Brick and Tile yards and the historic Holy Cross Church.
Wired internet here is mostly older DSL on copper lines, and satellite has been the fallback for households that need more. STI's Air Fiber is 400 Mbps down / 25 Mbps up for $65/month — no contract, and support from right down the highway in Hondo.
ZIP code served: 78850
Coverage note: Most addresses in 78850 are in coverage. Ranch properties and county-road addresses outside town depend on terrain and distance from our nearest tower, so call (830) 429-4149 to confirm.
D'Hanis is a short drive from our Hondo office, so installs and service calls don't take long. The 25 Mbps upload is a real step up from DSL for anyone working remotely or running a small business from home.
The town moved about a mile west to meet the railroad in 1881 — locals still call the original site "Old D'Hanis."
Nearby: STI also serves Hondo 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.
