Find South Dakota internet providers by city

South Dakota is perhaps best known as the home of Mt. Rushmore. It’s a big state with a fairly small population, just 925,000. But the cities of South Dakota are well connected to high-speed internet, with some providers offering download speeds of up to 1 Gbps.

South Dakota residents identify their state as East River or West River, meaning which side of the Missouri River they are on. All areas have access to satellite internet.

Some of the cities in the East River area include Sioux Falls, Aberdeen, Watertown, Pierre, Huron and Vermillion. Fiber internet is available in Sioux Falls, the largest city in the state. About 72% of Sioux Falls residents can access 1,000 Mbps plans with fiber providers like CenturyLink and Rise Broadband.

Residents in smaller towns can access larger satellite or fixed wireless carriers and regional providers like Wavelength and the James Valley Cooperative. Midco also provides 100% of Aberdeen addresses with fiber connections.

West River cities include Rapid City, Deadwood, Sturgis, Spearfish, Lead, Hot Springs and Hill City. Nearly all of Rapid City’s addresses are served by Midco with cable and fiber connections. Deadwood residents can access 5G home internet from Verizon and T-Mobile, as well as cable and fiber from Midco.

The future of internet in South Dakota

South Dakota’s ConnectSD initiative has been bringing fiber to more households across the state since 2019. The program is now in the final stages, with about 91% of South Dakota having access to broadband service.

Besides fiber, South Dakota is using a partnership with Starlink to “reach 2,705 of the 7,060 locations in the state targeted for the funds,” according to reports.

How we review internet in South Dakota

Using Allconnect and provider data, along with the broadband map of the Federal Communications Commission (FCC), our experts look at the number of internet providers available, the speed and cost of the plans, type of internet offered and how many addresses are serviced by the provider.

Our methodology

We evaluate broadband providers in four categories: affordability, performance, value and customer satisfaction.

We evaluate broadband providers in four categories: affordability, performance, value and customer satisfaction. Each category contains multiple sub-factors, all of which are weighted differently to impact the provider’s overall score.

For each sub-factor, we score all providers on a continuous scale of one to five, relative to the industry as a whole. Because the average download speed in America is currently 290 Mbps, for example, we assigned all plans with download speeds between 100 and 299 Mbps a score between three and four. Xfinity’s 200 Mbps plan received a 3.50 score for download speed, while Spectrum’s 500 Mbps plan got a 3.71.

We only considered standardized data points in our scoring system. More abstract data like consistency of service and brand reputation is still part of our analysis, but we opted to let our writers address them in the context of each review.
