Fontana, California internet providers and fiber

Fontana in California
Fiber in Fontana comes from two companies whose networks rarely meet: AT&T reports it at 18.7% of the city's homes and businesses and Frontier at 11.2%. Together with a little Spectrum fiber that adds up to 30.5%, up from 21.3%2 in 2022. At most other addresses the only wired connection at 100/20 Mbps is Spectrum's cable, which stands alone at 61.8%1 of locations.
Spectrum nearly everywhere, AT&T on three technologies
The FCC counts 51,236 homes and businesses in Fontana, each a "location" on its map. As of June 30, 2026 (revision of November 10, 2026), 8 companies report land-based internet service at some of them, 5 of those over wires. Spectrum reports service at 96.9%, mostly over cable, with downloads advertised up to 1 Gbps1.
AT&T's figure of 85.9% mixes three networks. It reports fiber at 18.7% of locations; elsewhere it offers DSL over telephone copper or fixed wireless, both advertised at 100 Mbps or less. AT&T offers 100/20 Mbps at 27.2% of the city. Frontier's footprint is smaller, 11.2%1, and nearly all fiber.

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 (Viasat, Starlink, HughesNet) report service at nearly every location and are left out of the table.
"Available" in this table means the provider says it could connect a location within ten business days. That is a filing, not a guarantee, and anyone can challenge it on the FCC map. Satellite is reported at every location and is left out of the counts that follow.
Two fiber networks that rarely overlap
Fiber reaches 30.5% of Fontana's locations, a share ranked 33rd lowest among the 343 cities of 100,000 or more. California's share is 47.8% and the national share 62.6%. The city's figure was 21.3%2 in June 2022 and 28.0%3 on December 31, 2025, so it has risen by 9.2 percentage points in four years, 2.5 percentage points1 of that in the last six months.
The two main fiber footprints sit side by side rather than on top of each other. AT&T fiber covers 18.7% of locations, Frontier fiber 11.2% and Spectrum fiber 2.3%, yet only 987 locations (1.9%) can choose between two fiber providers. Fewer companies report fiber in the city than in 2022: 51, against 32.
Over the same period, copper receded. DSL is reported at 65.7%1 of locations, down from 73.0%2 in 2022.

Less fiber than Ontario and San Bernardino
Frontier's fiber covers far more of some nearby cities than of Fontana. It is reported at 77.2% of locations in Ontario and 67.1% in San Bernardino, against 11.2% in Fontana. Rancho Cucamonga, at 21.7% fiber overall, is closer to Fontana's position, while AT&T's fiber reaches more of Fontana (18.7%) than of either Rancho Cucamonga (0.3%) or San Bernardino (1.1%1).

One wired choice at most addresses
Wired service at 100/20 Mbps is reported at 97.9% of Fontana's locations, but for most of them there is one such wire. Exactly one wired provider offers 100/20 Mbps at 62.7% of locations, the 35th highest share among large cities, and Spectrum is that provider at 61.8%. Two wired choices are reported at 35.2%, up from 28.5%2 in 2022, rising alongside fiber; three wired choices are reported at 0.0%. Across California, 49.9%1 of locations have two or more.
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.

| Ontario | 4.7% | 17.2% | 67.8% | 10.3% |
| California | 6.9% | 43.2% | 43.4% | 6.5% |
Most of the 1,091 locations (2.1%) without a wired 100/20 offer still have another option. At 230 of them fixed wireless is the only service at that speed, and only 71 locations in the city have satellite and nothing else.
Gigabit downloads everywhere, multi-gigabit on fiber
A 1 Gbps download is advertised at 97.7% of locations, almost all on Spectrum's cable. The FCC's stricter gigabit measure, 1,000 Mbps down with at least 100 Mbps up, is advertised at 30.5%, the 10th lowest share among large cities and close to the fiber share. That share stood at 31.7%3 on December 31, 2025 and fell by 1.2 percentage points1 in the latest filing, although fiber rose over the same period.
Fiber carries almost all of the city's fastest tier. Locations whose fastest advertised download is 2 Gbps or more made up 28.7% of the city, up from 16.5%2 in 2022; AT&T advertises up to 5 Gbps and Frontier up to 7 Gbps1. Every speed here is a provider's advertised maximum, not a measurement.

5G home internet, and a radio network filed for business
Ultimate Internet Access Inc lists an unlicensed radio network across Fontana, but files it as business-only service, so this page counts only its small residential fiber footprint, 0.3% of locations, advertised up to 8 Gbps1. The mobile carriers supply the residential fixed wireless.
Licensed fixed wireless, the category that includes 5G home internet, is reported at 91.4%. T-Mobile reports it at 76.1% of locations and Verizon at 65.8%, with maximum advertised downloads of 100 Mbps and 300 Mbps. Licensed fixed wireless at 100/20 Mbps or faster rose from 7.0% of locations in 2022 to 32.0%, below the 37.5%3 of December 31, 2025. Counting wireless and wired providers together, 14.3%1 of locations have three or more at 100/20, against 4.0%2 in 2022. Tower capacity is shared, so a location on the map is not a promise of a connection.
Satellite on the bill in a wired city
The Census Bureau's 2025 survey counts households, not locations, and its figures are estimates with margins of error. In Fontana, 10.1% of households reported a satellite internet subscription (±2.3 percentage points), a point estimate ranked tied for 14th highest among large cities, although satellite-only locations on the FCC map number 71. California's estimate is 7.8%4; with Fontana's margin of error, the two are not clearly different. The survey does not say why households chose satellite.

| Area | Households with satellite internet | MOE |
|---|---|---|
| Fontana | 10.1% | ±2.3 |
| California | 7.8% | ±0.2 |
| San Bernardino | 7.2% | ±2.0 |
| Rancho Cucamonga | 6.9% | ±2.1 |
| Ontario | 6.5% | ±2.1 |
The clearer change is in how many households are connected at all. Households without an internet subscription fell from 10.3% in 2019 (±2.4 percentage points) to 2.9% (±1.4 percentage points), and those relying only on a cellular data plan rose from 5.7% (±1.3 percentage points5) to 14.4% (±2.8 percentage points); in both cases the ranges do not overlap. Cable, fiber or DSL subscriptions stood at 79.8% (±2.9 percentage points4).

Checking one address in Fontana
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.
