Serving 30+ communities across Medina, Atascosa, Frio, and surrounding counties.
South Texas Internet provides fixed wireless Air Fiber internet to more than 30 communities across Medina, Atascosa, Frio, Bexar, and Uvalde counties. Our tower network stretches from Hondo and Castroville in the north to Dilley and Poteet in the south, covering the rural roads, ranches, and small towns that major carriers have largely skipped. Every customer gets the same plan — 400 Mbps for $65/month flat — regardless of which county they're in.
Each circle represents approximately 10 miles of coverage around a tower location.
Not sure if we cover your address?
Check AvailabilityCoverage depends on line-of-sight from the nearest tower. Most addresses within city or town limits can be confirmed the same day you call — we'll tell you right away whether we can serve you. Rural ranch addresses and properties on the edge of a coverage circle should call (830) 429-4149 so we can verify line-of-sight before scheduling an install. There's no commitment required to check.
