Internet providers in Rialto, California

Who reports service in Rialto

As of June 30, 2026 (FCC revision of November 10, 2026), 8 companies report land-based internet service somewhere among Rialto's 24,550 locations, the FCC's count of houses, apartment buildings and businesses that can be connected. Two of them run wires across most of the city: Spectrum, whose cable network is reported at 96.4% with downloads advertised up to 1 Gbps, and AT&T, reported at 85.5% but offering 100/20 Mbps at only 26.3%¹.

A listing means the provider told the FCC it could connect the location within ten business days; anyone can challenge it on the FCC map, which is also the place to check a single address. HughesNet, Viasat and Starlink report satellite service at every location and are left out of the counts of choice below.

Spectrum alone at nearly three addresses in four

Wired service of 100/20 Mbps or more is reported at 97.4% of Rialto's locations, so fast wired internet is almost universal. A second wire at that speed is not. At 72.2% of locations exactly one wired provider offers 100/20, and Spectrum is that provider at 71.2%. Two or more wired providers are reported at 25.2%, the 16th lowest share among large cities, against 49.9%¹ across California.

The single-wire share was higher in 2022, at 80.2%², and has fallen 8.1 percentage points since. Over the same period fiber grew 11.8 percentage points¹, adding a second wire at some addresses that had only Spectrum.

AT&T's fiber grows beside its copper

Fiber from any provider is reported at 20.7% of locations, up from 9.0%² in June 2022 and 18.1%³ in December 2025. AT&T accounts for most of it, reporting fiber at 18.2% with a top advertised download of 5 Gbps. Hotwire Communications reports fiber at 647 locations, and Spectrum reports fiber rather than cable at 0.9% of the city. Two or more fiber networks at the same address are reported at 285¹ locations.

Unlike several of its neighbors, Rialto still has AT&T's telephone copper on the map. DSL is reported at 71.7% of locations, the 66th highest share among large cities, down 6.2 percentage points¹ since 2022.

Where Frontier's fiber stops

Fiber coverage changes sharply between Rialto and the cities around it. Frontier reports fiber at 67.1% of locations in San Bernardino and 77.2% in Ontario, and at 11.2% in Fontana. In Rialto it reports fiber at 60 locations, or 0.2%¹.

Across these few cities, then, the typical address goes from fiber and cable in San Bernardino and Ontario to cable alone in Rialto. Among the cities in the table, Rialto's pattern is closest to Rancho Cucamonga's in wired choice, but with far more copper still reported.

Gigabit uploads: fewer than in December

Downloads of 1 Gbps are advertised at 97.2% of locations, mostly over Spectrum's cable. Gigabit service with uploads of 100 Mbps or more, the FCC's 1,000/100 tier, is a different matter: it is reported at 20.7% of locations, the 6th lowest share among large cities, against 67.4%¹ statewide.

That share fell between the last two releases. In December 2025, 1,000/100 service was reported at 27.2% of locations, more than the 18.1%³ with fiber, so some network other than fiber was reporting it then. In June 2026 the tier covers 20.7%, almost exactly the fiber share. The change, −6.5 percentage points, ranks 9th lowest¹ among large cities. Providers revise their filings with each release; the FCC data record what was reported, not why it changed. All speeds here are advertised maximums, not measurements.

5G home internet beside the wires

Ultimate Internet Access Inc lists an unlicensed radio network across nearly the whole city, but it files that Rialto service as business service only, so it is not counted here, and no unlicensed fixed wireless remains in the residential count (0.0%). Counting wired providers and the mobile carriers, 11.2%¹ of locations have three or more land-based providers of any kind at 100/20 Mbps.

The carriers' 5G home internet has spread since the first map. Licensed fixed wireless at 100/20 Mbps or faster was reported at 7.1%² of locations in June 2022 and at 32.8% in June 2026. Verizon reports home internet at 63.8% of locations, up to 300 Mbps; T-Mobile at 79.1%¹. Fixed wireless capacity is shared on each tower sector, so these shares show where the carriers report service, not where every home could sign up at once.

Only fixed wireless reaches 100/20 Mbps at 103 locations (0.4%). By the federal BEAD definitions, 59¹ locations are unserved, lacking a wired or licensed fixed wireless connection of 25/3 Mbps.

What Rialto households subscribe to

The Census Bureau's 2025 survey counts households, not locations, and carries a margin of error. In it, 95.8% of Rialto households had a broadband subscription (margin of error ±2.4 percentage points) and 77.5% subscribed to cable, fiber or DSL (±2.2 percentage points). 15.3% relied only on a cellular data plan (±4.4 percentage points). Satellite subscriptions were reported by 11.6% of households (±3.1 percentage points), the 7th highest estimate among large cities and above the California figure of 7.8%⁴, in a city where land-based service of 25/3 Mbps is reported at 98.8%¹ of locations.
