San Antonio in Texas
San Antonio has more fiber, by share of homes and businesses, than any of Texas's other four largest cities: 88.2%, mostly from AT&T and Google Fiber. Spectrum's cable reaches nearly everyone, and a local wireless company, Alamo Broadband, now reports service at 33.2%1 of the city.
Spectrum, AT&T, Google Fiber and a long list
San Antonio's 425,665 homes and businesses are served by an unusually long list of companies. 18 providers report wired or fixed wireless service somewhere inside the city limits as of June 30, 2026, a count that ranks tied for 6th highest among the 343 cities of 100,000 or more. 10 of them run wired networks and 91 report fiber; beyond the four largest networks, each reports service at only a small share of the city.

Source: FCC, National Broadband Map, data as of June 30, 2026. Share of the area's broadband serviceable locations where the provider reports service as of June 30, 2026. "Only wired option" is the share of locations where it is the single wired provider at 100/20 Mbps. Provider-reported and challengeable; speeds are advertised maximums, not measured; no prices. Satellite providers (HughesNet, Viasat, Starlink) report service at nearly every location and are left out of the table.
Four wired networks cover the most locations. Spectrum reports cable at 96.7% of locations. AT&T reports service at 92.9%, a mix of fiber (63.7% of locations), older DSL and fixed wireless. Google Fiber reports 45.4%, almost all of it fiber. Astound reports 9.5%1, mostly cable. "Reports service" means the provider told the FCC it can connect a location within ten business days; the claim can be challenged on the FCC map.
Fiber reaches nine in ten locations
At least one fiber provider reports service at 88.2% of San Antonio's locations, a share that ranks tied for 90th highest among large US cities, against 74.4% for Texas and 62.6% nationally. The city started from a high base: fiber was already reported at 72.4%2 of locations in June 2022, so its gain since then, +15.7 percentage points, is smaller than the statewide gain of +28.8 percentage points. Since December 2025 the share has moved by only +0.4 percentage points1.
What changed more is overlap. The share of locations with two or more different fiber providers rose from 13.4%2 in June 2022 to 24.8%, mostly where AT&T and Google Fiber overlap. Google Fiber now reports 193,3171 locations in the city.

Beside Houston, Dallas, Fort Worth and Austin
Among the five largest Texas cities, San Antonio has the highest fiber share and the smallest share of locations with only one wired option. Austin, the only other one of the five where Google Fiber reports service, has more two-fiber overlap. Houston and Dallas report more fiber companies in total but very little overlap between them.

Spectrum is the lone fast wire at one in ten
Wired service of at least 100/20 Mbps is reported at 98.2% of locations. At 11.0% only one wired provider offers that speed; Spectrum's cable network is that one provider at 9.8%1. That single-wire share has roughly halved since June 2022, when it was 21.5%2, over the same years that fiber's reach grew.
Source: FCC, National Broadband Map, data as of June 30, 2026. Different wired providers (fiber, cable or DSL; FCC provider IDs) reporting 100 Mbps down and 20 Mbps up or more at the same location. Fixed wireless and satellite are not counted.

| United States | 7.8% | 36.6% | 44.6% | 11.1% |
AT&T's footprint is the reason the wired count looks larger than it is in some neighborhoods. DSL is still reported at 33.3% of locations, down from 40.8%2 in June 2022, and AT&T offers 100/20 Mbps at 70.1% of locations, well below its overall 92.9%1. Where AT&T has only copper, it does not count as a competing 100/20 wire.
Only 344 locations in the city lack any wired or licensed fixed wireless service of 25/3 Mbps, and 1141 can get only satellite.
A local wireless network across a third of the city
Unlicensed fixed wireless, radio service on shared spectrum from rooftop or tower antennas, is reported at 40.8% of San Antonio's locations, up from 6.0% in June 2022. Texas as a whole moved the other way, to 30.0% from 43.8%2. Most of the city's figure is one company: Alamo Broadband reports this service at 141,306 locations (33.2%), with a fastest advertised download of 990 Mbps. That is most of the 225,001 locations it reports nationwide, all in Texas. VTX Communications adds licensed and unlicensed wireless at 19.4%1.

The mobile carriers report their home internet even more widely: Verizon at 87.1% of locations (100/20 Mbps at 55.4%) and T-Mobile at 83.5% (100/20 at 27.4%1). Fixed wireless capacity is shared by everyone on an antenna, so providers limit sign-ups by address; the FCC figures show where it is reported, not how many homes could join at once.
Advertised speeds: multi-gigabit is common
The fastest advertised download is 2 Gbps or more at 72.7% of locations, up from 15.6%2 in June 2022; AT&T advertises up to 5 Gbps on fiber and Google Fiber up to 8 Gbps. Gigabit with uploads of 100 Mbps or more (the FCC's 1,000/100 tier) is reported at 88.2%, which is 2.9 percentage points1 lower than in December 2025, while fiber's reach held steady. The FCC data record what providers report, not why a reported tier changed. Every speed here is an advertised maximum, not a measurement.

Subscriptions have caught up with the wires
The Census Bureau's American Community Survey counts households, not locations, and is an estimate. In 2025, 94.4% of San Antonio households had a broadband subscription (margin of error ±0.8 percentage points), against 83.1% in 2019 (±1.0 percentage points); the two estimates are clearly apart. The share with no internet subscription fell from 16.7%5 to 5.6%. Wired subscriptions (cable, fiber or DSL) stood at 78.3% (±1.6 percentage points), and 14.0%4 of households relied only on a cellular data plan.

Checking one address in San Antonio
The figures on this page describe the whole area. Which providers report service at a single home or apartment is shown only on the FCC's own map: search the address at broadbandmap.fcc.gov. If a provider is listed there but cannot actually connect you within ten business days, or the location is missing or misplaced, the map has a button to file a challenge; providers must respond, and corrections flow into later releases. Prices and plans are not part of the FCC data: each provider must show them on its broadband facts label at the point of sale.
