High-Speed Internet in Derby, TX $65/month Flat Rate

Zip codes served: 78861 area — Derby is a small community along the US-90 corridor in Medina County, served under the Hondo zip code district without a dedicated zip code.

Derby sits along the old Highway 90 route between Hondo and Castroville, in Medina County's agricultural core. The US-90 corridor has some AT&T DSL availability — legacy copper infrastructure that services towns along the old highway — but speeds are limited and fiber has not reached this stretch. Spectrum does not serve rural Medina County. Starlink has been the practical choice for residents wanting broadband that actually works.

The land along this stretch of US-90 is a mix of farming operations, ranch properties, and rural homesteads that have been here for generations. That land use pattern means dispersed residences with specific line-of-sight requirements for fixed wireless coverage. STI's network is built on towers spread across Medina County specifically to reach this kind of geography — small communities and rural addresses strung along state highways and farm-to-market roads.

Coverage along the US-90 corridor between Hondo and Castroville is generally good from our existing tower infrastructure, but individual properties can vary. If your address is off the highway on a county road or down a private lane, call us before scheduling to confirm we can reach your specific location.
