Zip codes served: 78850
D'Hanis is one of the smaller incorporated communities along US-90 in Medina County, about 12 miles west of Hondo. AT&T offers DSL service in D'Hanis on older copper infrastructure, but speeds top out at 10–25 Mbps on a good day and are often lower. AT&T has not extended fiber to 78850. Spectrum does not serve D'Hanis. Starlink is the most common alternative for residents who need real bandwidth.
The community is anchored by its Alsatian heritage — the Holy Cross Church and the legacy of the D'Hanis Brick and Tile operation are central to the town's identity. Established families with deep roots here increasingly have members working remotely or running small businesses from home. The D'Hanis Alsatian Museum draws visitors, and the local economy depends on connectivity as much as any community its size.
STI covers D'Hanis from our Medina County network, which is centered in Hondo. Most addresses in 78850 fall within our service area, and installs are typically completed quickly given our operational base is close by. Upload matters here too — 25 Mbps up is what remote work and video calls run on, and it's a significant step up from DSL in this area.
If you're on a rural address outside D'Hanis proper — on a county road or ranch property — call to confirm line-of-sight coverage before scheduling. Rural addresses within 78850 can vary depending on terrain and distance from our nearest tower.
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.
