San Francisco in California
San Francisco is served by three main wired networks and by as many licensed fixed wireless companies as any other large US city. Xfinity reaches 98.7% of its homes and businesses, fiber from AT&T, Sonic and smaller builders reaches 60.8%, and 71 companies report licensed fixed wireless service.
Xfinity, AT&T and Sonic: three wired networks
Three companies have the widest wired networks in San Francisco, as reported to the FCC as of June 30, 2026 (revision of November 10, 2026). Xfinity's network reaches 98.7% of the city's 146,083 homes and businesses and advertises up to 2 Gbps, the top tier coming from a small fiber footprint (0.1% of locations). AT&T reports service at 98.0% of locations, but fiber at only 37.5%; the rest is DSL over copper phone lines or fixed wireless. Sonic is fiber only and reports it at 48.7% of locations, with advertised downloads up to 10 Gbps. Astound adds cable and some fiber at 26.1%1.

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 (Starlink, HughesNet, Viasat) report service at nearly every location and are left out of the table.
A provider counts as available where it reports that it can install standard service within ten business days. Reports can be challenged on the FCC National Broadband Map, which is also the place to look up one apartment or house. HughesNet, Starlink and Viasat report satellite service at every location, but no location in the city depends on satellite alone (0.0%1).
Fiber: ahead of California, behind the East Bay
Fiber from at least one provider reaches 60.8% of San Francisco's locations. That is well above the California share of 47.8%, below the national 62.6%, and a share that ranks tied for 120th lowest among the 343 cities of 100,000 or more. Across the Bay the figures are higher: 90.1% in Oakland and 91.6% in Berkeley. Daly City, on the city's southern border, reports 76.9%1.

| San Francisco | 60.8% |

The fiber map is crowded with names: 9 companies report fiber somewhere in the city, a count tied for 12th highest among large cities. Apart from Sonic and AT&T, they report fiber at small numbers of locations: Google Fiber, for example, reports 646 locations. Where fiber networks overlap, a home can choose between fiber providers; 26.8% of locations have two or more, up 5.6 percentage points1 since June 2022.
Sonic is not a newcomer: in the June 2022 data it filed under the name Sonic.net, so the provider list shows it as new when its network was already there. Fiber coverage as a whole rose by only 5.3 percentage points over the four years, from 55.5%2 to 60.8%1.
Where Xfinity is the only fast wire
Wired service of at least 100/20 Mbps reaches 99.1% of locations. At 71.1% two or more wired companies offer that speed, against 49.9% across California and 55.6% nationally. The single-wire share is 27.9%, and at almost all of those locations (27.7%1 of the city) the one wire is Xfinity's. At those addresses neither AT&T nor Sonic reports wired service at that speed.
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.

| California | 6.9% | 43.2% | 43.4% | 6.5% |
| United States | 7.8% | 36.6% | 44.6% | 11.1% |
A small group has no wired option at that speed: 1,372 locations, and fixed wireless covers 1,330 of them at 100/20 Mbps. The FCC counts 11 location in the city as unserved under the federal BEAD definition, with no reliable wired or licensed fixed wireless service of at least 25/3 Mbps.
Local radio networks beside the 5G carriers
San Francisco has an unusual number of fixed wireless providers, which send service by radio to an antenna on the building. 7 companies report licensed fixed wireless here, a count tied for 2nd highest among large cities, up from 32 in June 2022. Two local networks report the widest reach and offer 100/20 Mbps across their footprints: Unwired at 87.3% of locations and Etheric Networks at 69.7%, each advertising up to 250 Mbps. The mobile carriers' home internet reaches nearly as far, but offers 100/20 Mbps at fewer locations: Verizon reports 82.9% of locations, with 100/20 Mbps at 35.6%, and T-Mobile 67.5%, with 100/20 at 21.8%1.
The wireless figures shifted after 2022. In June 2022 unlicensed fixed wireless was reported at 97.0% of locations and licensed fixed wireless at 100/20 Mbps at only 7.9%. By June 2026 those figures were 0.4% and 98.6%, a licensed share that ranks tied for 5th highest among large cities. The chart below also shows the decline in reported DSL, from 90.3%2 to 65.1%1.

Gigabit service with uploads of at least 100 Mbps (the FCC's 1,000/100 tier) is advertised at 79.6% of locations, up 23.9 percentage points since June 2022, and symmetrical wired service of 100/100 Mbps or more at 79.4%, up 23.9 percentage points1.

More households online, more of them by phone plan
Subscriptions are a different measure from availability: the Census Bureau surveys households, while the FCC counts locations. In the 2025 American Community Survey, 6.0% of San Francisco households had no internet subscription (margin of error ±0.9 percentage points), down from 10.2% in 2019. The share relying only on a cellular data plan rose from 7.9% to 12.4% (margin ±1.2 percentage points). Subscriptions to cable, fiber or DSL, at 79.4%4 against 80.3%5 in 2019, did not change by more than the survey's margins.

Checking one address in San Francisco
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.
