Home internet in Springfield, Illinois
Fiber is available at 62.6% of the 47,079 homes and businesses the FCC counts in Springfield, and wired broadband of at least 100/20 Mbps at 99.7%. 64.6% of locations have a choice of two or more wired providers at that speed; at 35.2% there is only one.1

Springfield in Illinois
Springfield's wires reach almost every address: Xfinity's cable network covers 99.7% of homes and businesses and fiber 62.6%1, well above the Illinois share. Yet in the Census Bureau's survey 23.5% of its households relied only on a cellular data plan, the 2nd highest2 share among large US cities.
Xfinity, AT&T and two local fiber companies
Springfield has 47,0791 homes and businesses on the FCC's location list (locations, not households), and the table shows every provider that reports service at them as of June 30, 2026, in the file revision of November 10, 2026. "Reports service" means the provider tells the FCC it could install service there within ten business days; residents can challenge the claim on the FCC map.

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.
Two wired names reach most addresses. Xfinity's cable network covers 99.7% of locations and offers 100/20 Mbps at all of them. AT&T reports 91.7%, but on three different technologies: fiber at 45.3% of locations, and DSL or fixed wireless, each with an advertised maximum of 100 Mbps, at most of the rest. AT&T offers 100/20 Mbps at 51.9%1 of locations.
The fiber-only companies are smaller and local in footprint. i3 Broadband reports fiber at 25.5% of locations, and Computer Techniques adds fiber at 2.0%. Satellite from Starlink, HughesNet and Viasat is reported at every location, as it is across almost the whole country; only 41 locations have satellite and nothing else.
One wired choice at three locations in ten
Wired service of at least 100/20 Mbps is reported at 99.7% of locations; only 131 locations have none. The question in Springfield is how many wires compete. At 35.2% of locations exactly one wired provider offers 100/20 Mbps, down from 48.8%3 in June 2022, and that provider is Xfinity at 35.1%. Two or more wired choices are reported at 64.6%, against 56.4% statewide and 77.6%1 in Peoria.
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.

The single-wire share has fallen in each release since 2022: since December 31, 2025 alone it dropped by 2.7 percentage points1.
Fiber at two locations in three
Counting all 3 providers that report it, fiber reaches 62.6% of Springfield's locations, up 17.3 percentage points from 45.3%3 in June 2022. That is well above the Illinois share of 48.4% and about the same as the national 62.6%, though below Peoria, where fiber reaches 77.8%1.
The fiber networks mostly reach different locations. Two or more fiber providers overlap at 10.2%1 of locations, up from 3.8%3 in 2022.

Source: FCC, National Broadband Map, data as of June 30, 2026. FCC file revision of November 10, 2026. Shares are of broadband serviceable locations (homes and businesses), not people.
Speeds: multi-gigabit tiers and faster uploads
The fastest advertised download is 2 Gbps or more at 69.3% of locations, against 18.5%3 in June 2022. Gigabit service with uploads of 100 Mbps or more (the FCC's 1,000/100 tier) is advertised at 72.7% of locations, up 27.3 percentage points since 2022. Because that share is larger than the fiber share, part of it is advertised over cable. Xfinity's cable network advertises up to 2 Gbps; on fiber, i3 Broadband's 8 Gbps and AT&T's 5 Gbps1. All are maximums providers advertise to the FCC, not measured speeds.
Fixed wireless from three carriers and smaller operators
T-Mobile reports fixed wireless home internet at 86.7% of locations, with 100/20 Mbps at 37.4%. Verizon, which reported only a small part of the city in June 2022, now reports 85.0%, with 100/20 Mbps at 36.3%. AT&T adds its own fixed wireless service. Rise Broadband reports 45.2%, Royell Communications 6.3% and Nextlink 2.2%1.
Licensed fixed wireless at 100/20 Mbps or more is reported at 78.2%1 of locations, against 18.3%3 in June 2022. The share was higher in December 2025 (90.3%4), a reminder that fixed wireless filings move between releases. Carriers also limit sign-ups by address, because a tower sector's capacity is shared. The figures show where service is reported, not where every home could join at once.
Wired everywhere, yet many homes on phone data
Springfield's distinctive number comes from the Census Bureau, not the FCC. In the 2025 American Community Survey, 23.5% of Springfield households had a cellular data plan and no other internet subscription (margin of error ±4.1 percentage points), while 69.8% subscribed to cable, fiber or DSL (±4.0 percentage points2). Set against networks that reach almost every address, that is a wide gap between what is available and what is bought.
Source: FCC, National Broadband Map, data as of June 30, 2026; Census Bureau, American Community Survey 2025 1-year detailed tables. Availability is a share of locations as of June 30, 2026 (FCC); subscriptions are a share of households from the American Community Survey, 2025 (whiskers: 90% margin of error). Different units and dates: read the gap as a sign, not an exact number.
Show the numbers
| Measure | Share | MOE |
|---|---|---|
| Wired 100/20 Mbps available (FCC, share of locations) | 99.7% | |
| Households subscribing to cable, fiber or DSL (Census) | 69.8% | ±4.0 |
| Households relying only on a cellular data plan | 23.5% | ±4.1 |
| Households with no internet subscription | 5.0% | ±1.9 |
The survey counts households over a year and the FCC counts locations on one date, so the two sets of figures describe different things and should not be subtracted from each other.
Only one large US city had a higher cellular-only point estimate than Springfield; the Illinois share is 14.9%2. Even at the low end of its margin, Springfield's share is above the state's.

The share has grown. In the 2019 survey, 12.2% of households relied only on cellular data (±2.6 percentage points), and 20.7% had no subscription at all (±3.5 percentage points). By 2025 the share without a subscription had fallen to 5.0% (±1.9 percentage points2). The cable, fiber or DSL share was 64.4% in 2019 (±2.9 percentage points5), within the margins of the 2025 figure. On these estimates, most of the gain in subscriptions since 2019 shows up as cellular-only plans rather than wired service. The survey does not record why.

Checking one address in Springfield
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.
