A building that no wired network reaches still has options on paper: T-Mobile Home Internet for 5G home, filed in each of the 45 ZIP codes, and satellite (Starlink, Viasat, HughesNet) at any address.
Every San Antonio ZIP code has AT&T Fiber and Spectrum on file, so the wired choice never narrows to one network at the ZIP level. Multi-gig service (2 Gbps and up) is on file from Hotwire Communications (8 Gbps), Google Fiber (8 Gbps), and AT&T Fiber (5 Gbps). The widest wired networks aren’t the ones with the top filed speed — AT&T Fiber tops out at 5 Gbps, Hotwire Communications at 8 Gbps (32 of the 45 ZIP codes).
