South Dakota internet, where fiber outran cable

Fiber is available at 61.8% of the 393,489 homes and businesses the FCC counts in South Dakota, and wired broadband of at least 100/20 Mbps at 94.4%. 41.3% of locations have a choice of two or more wired providers at that speed; at 53.1% there is only one.1

FCC National Broadband Map, availability as of June 30, 2026 (data revised November 10, 2026), as reported by providers.

Midwest region, West North Central division

Cable reaches 50.7% of South Dakota's homes and businesses, the lowest1 share of any state, and much of its wired service comes from local fiber networks instead. Those networks reach many small rural counties more completely than Rapid City and the Black Hills, while a handful of counties west of the Missouri River hold the state's largest gaps.

Who reports home internet in South Dakota

As of June 30, 2026 (FCC data revised November 10, 2026), 57 providers report wired or fixed wireless service somewhere in South Dakota. Reach and speed rank them very differently. Two of the three widest networks are licensed fixed wireless, the category that includes 5G home internet: T-Mobile reports service at 55.6% of the state's 393,489 homes and businesses and Verizon at 51.6%, but they offer 100/20 Mbps at only 16.6% and 21.9%. AT&T's fixed wireless service, absent from the 2022 map, now appears at 25.1%1 of locations.

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.

Among wired networks, Midco has the largest footprint, at 56.4% of locations, mostly cable with fiber at 7.8%; it is the only wired 100/20 provider at 15.1%. Bluepeak follows at 32.0%, with fiber at 8.5%. CenturyLink reports service at 42.7%, nearly all of it DSL: it offers 100/20 Mbps at just 1.7%1.

Smaller local companies supply much of the rest of the wired map. Golden West Telecommunications reports fiber at 11.4% of the state's locations and is the only wired 100/20 provider at 11.2%, nearly as many as Midco. ITC (5.8%), Venture Communications Cooperative (5.1%) and Northern Valley Communications (4.6%) are other local networks whose service is mostly or entirely fiber. Altogether 421 providers report fiber in the state.

Cable reaches only about half the state

Cable is reported at 50.7% of South Dakota's locations, ranking the lowest among the 50 states and DC, against 80.3% nationally. The share has slipped by 2.6 percentage points since June 2022. Fiber, at 61.8%1, now reaches more of the state than cable does.

Small counties on fiber, the Black Hills on cable

The statewide fiber share, 61.8%, ranks only 20th lowest among the states, below the national 62.6%. County by county the picture is close to the opposite: fiber reaches half or more of the locations in 56 of South Dakota's 662 counties, and in Walworth, Sully, Perkins, Hyde, Harding and other small counties it rounds to 100.0%1. The state figure is pulled down by a few populous counties where cable, not fiber, is the main wire.

Wired 100/20 service is also less complete in the Black Hills: 74.2% of Lawrence County's locations and 85.0% of Meade County's, against 94.4%1 statewide.

One wire for half the state

Wired coverage at 100/20 Mbps reaches 94.4% of locations, but at 53.1% exactly one wired provider offers it, the 7th highest share among the states. Two or more wired choices are reported at 41.3%, against 55.6% nationally, and three or more at only 1.6%. Since June 2022 the share with two or more rose by 11.5 percentage points, the 10th lowest1 gain of any state.

Choice comes where networks overlap. In Sioux Falls 67.1% of locations have two or more wired providers, and in Pennington County 62.4%. Hughes County, which includes Pierre, the state capital, shows the other pattern: wired 100/20 service reaches 99.2% of its locations, but 96.7% have exactly one wired provider. Locations reached by two fiber networks are rare: 5.5% statewide, against 12.1%1 nationally.

Since 2022: gigabit offers more than doubled

The fastest change since 2022 has been in speed. A gigabit offer (1,000/100 Mbps) was reported at 26.7% of South Dakota's locations in June 2022 and at 74.8% in June 2026, and symmetrical wired 100/100 service rose from 38.9%3 to 76.7%. Fiber's share rose by 22.9 percentage points over the same four years, a smaller gain than the national 25.4 percentage points1.

West of the river, fiber on the map and gaps beside it

Statewide, 9,428 locations (2.4%) are unserved under the BEAD definition, without reliable service of at least 25/3 Mbps, down from 7.8%3 in June 2022; 7,1921 more are underserved, with service below 100/20 Mbps. The counties with the highest shares are all west of the Missouri River.

Competition is almost absent here: in Bennett County, Corson, Dewey, Todd and Ziebach counties, the share of locations with two or more wired providers at 100/20 Mbps rounds to zero. And fiber does not always mean a gigabit offer: in Dewey County fiber reaches 87.1% of locations but a 1,000/100 Mbps offer only 1.7%1.

Subscriptions trail the wires

Coverage does not settle whether households sign up. In the Census Bureau's 2025 survey, 8.0% of South Dakota households had no internet subscription of any kind (margin of error ±0.8 percentage points), ranking tied for 6th highest among the states by point estimate. Few rely on a phone plan alone: 11.5% had only a cellular data plan, the 7th lowest share. Income separates subscribers clearly: 78.7% of households earning under $20,000 had broadband (margin ±3.5 percentage points), against 95.9%5 of those earning $75,000 or more.

The FCC map contains no prices, and no official source publishes typical South Dakota prices. Lifeline, which takes $9.25 off the phone or internet bill of eligible low-income households each month, had 8,0816 South Dakota subscribers, an estimated 10.2%7 of those eligible. The Affordable Connectivity Program had 24,1948 South Dakota households enrolled when it stopped taking sign-ups in February 2024; it ended on June 1, 2024. In NTIA's 2023 Internet Use Survey, 20.5%9 of the state's households that did not use the internet at home named cost as the main reason, an estimate with a wide margin.

BEAD: a small plan at a high cost per location

South Dakota spends little of its $207.2 million10 Broadband Equity, Access, and Deployment (BEAD) allocation, but at a high price per location. Its approved Final Proposal, published by the South Dakota Governor's Office of Economic Development, covers 7,060 locations at a BEAD cost of $72.8 million. That is $10,312 per location, the 4th highest among the states with a plan; providers committed a further $18.5 million11.

Fiber is assigned to 4,178 of the plan's locations (59.2%) and low-Earth-orbit satellite to 2,705 (38.3%, the 7th highest satellite share of any state plan); fixed wireless gets 177. Of the allocation, $134.4 million11 is not assigned to construction in the plan, and how that money may be used was not settled as of November 2026; in September 2026 the state's BEAD office said it was developing its process for NTIA's new BEAD Supplemental Deployment Policy. Two older federal programs also fund South Dakota networks: the state's Capital Projects Fund allocation from the Treasury was $115.9 million12, and USAC records 2,92813 South Dakota locations built with Rural Digital Opportunity Fund support.

Questions and answers

What internet providers serve South Dakota?

Apart from satellite, the providers with the widest reported reach are Midco (56.4% of locations, mostly cable), T-Mobile (55.6%) and Verizon (51.6%), both licensed fixed wireless, then CenturyLink (42.7%, mostly DSL) and Bluepeak (32.0%1). Local fiber networks such as Golden West Telecommunications, ITC, Venture Communications Cooperative and Northern Valley Communications cover most of the rest. Figures are as of June 30, 2026.

How much of South Dakota has fiber internet?

At least one provider reports fiber at 61.8% of South Dakota's 393,489 homes and businesses as of June 30, 2026, up from 38.9%3 in June 2022. Fiber reaches half or more of the locations in 56 of the state's 662 counties, but only 6.1% in Lawrence County and 18.7%1 in Pennington County.

How many South Dakota homes lack broadband?

The largest gaps are west of the Missouri River, in Todd, Mellette, Corson and Oglala Lakota counties. Statewide, counting FCC locations rather than people, 9,428 homes and businesses (2.4%) were unserved under the BEAD definition, with no reliable service of at least 25/3 Mbps, and 7,192 more were underserved. At 2,3651 locations only satellite providers report service.

How much BEAD money does South Dakota get?

$207.2 million10. South Dakota's approved plan covers 7,060 locations at a BEAD cost of $72.8 million, or $10,312 each, the 4th highest among the states; $134.4 million11 is unassigned.

Checking one address in South Dakota

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.
