Best Internet Providers in South Dakota
Our Experts
What is the best internet provider in South Dakota?
Midco is the best internet service provider overall for most households in South Dakota because of availability, affordability and a solid customer service reputation. That being said, Midco service isn’t available everywhere in South Dakota, so Bluepeak or Golden West are also solid picks, depending on what’s available in your area.
We've also found the top options if you're hunting for the lowest prices or fastest speeds. The cheapest wired internet in South Dakota comes from Midco's $29 introductory deal for its 250 megabits per second plan, though you may find the starting price is higher in some locations. The fastest internet speed in South Dakota is 5,000Mbps (five gigabits per second) from Bluepeak and Midco, but it's found only within their limited fiber footprints. There are more ISPs in South Dakota than we've included in this guide. You may find smaller providers and local cooperatives that provide broadband to specific parts of the state.
Our methodology
CNET considers speeds, pricing, customer service and overall value to recommend the best internet service in South Dakota across several categories. Our evaluation includes referencing a proprietary database built over years of reviewing internet services. We validate that against provider information by spot-checking local addresses for service availability. We also do a close read of providers' terms and conditions and, when needed, will call ISPs to verify the details.
Despite our efforts to find the most recent and accurate information, our process has some limitations you should know about. Pricing and speed data are variable: certain addresses may qualify for different service tiers, and monthly costs may vary, even within a city. The best way to identify your options is to plug your address into a provider's website.
Also, the prices, speed and other information listed above and in the provider cards below may differ from what we found in our research. The cards display the full range of a provider's pricing and speed across the US, according to our database of plan information provided directly by ISPs. At the same time, the text is specific to what's available in South Dakota. The prices referenced within this article's text come from our research and include applicable discounts for setting up automatic payments each month -- a standard industry offering. Discounts and promotions might also be available for signing a term contract or bundling multiple services.

Best internet in South Dakota
Midco
Best internet provider in South Dakota
Our take - Midco takes the top spot for South Dakota ISPs thanks to availability, good top speeds, a limited fiber footprint and a solid customer service reputation. Midco uses a mix of cable, fiber and fixed wireless networks to fuel its large coverage area.
Bluepeak
Cheapest fiber internet in South Dakota
Our take - Midco’s closest competitor is Bluepeak, formerly called Vast. The two ISPs even go head to head in some areas. Bluepeak is worth weighing against Midco, especially if you can get the ISP’s fast, affordable fiber offering.
Golden West
Best rural internet in South Dakota
Our take - Living in a rural community in South Dakota doesn't have to mean suffering through slow internet. Golden West is focused firmly on fiber, though it still has a small DSL footprint. Speeds up to a gig make this a great option for a fast connection in a small town.
Starlink
Best satellite internet in South Dakota
Our take - Satellite internet is often a last resort when wired options or fixed wireless doesn’t work out. South Dakota’s large stretches of remote and rural areas make it a prime place for satellite. Starlink’s potential for faster speeds than its competitors gives it an edge in our recommendations for South Dakota.

Rural internet options in South Dakota
- Celerity Internet: Celerity started in the Spearfish area and expanded its fixed wireless network from there. It now covers broad areas around Deadwood and Rapid City and across the central-eastern region of the state. Plans start at $55 per month for 25Mbps and go up to $105 monthly for 100Mbps with a one-year contract. There are no data caps. Celerity also provides fiber to Prairie Haven Estates in Piedmont. Here’s how fixed wireless compares to other types of internet connections.
- CenturyLink: CenturyLink’s old-school DSL network reaches around Rapid City and Pierre and covers some eastern parts of the state. It may be the only wired option for some rural homes. There’s one plan at $55 per month with an optional $15 per month equipment lease. Speeds, however, may be slow. If you’re lucky, you may be able to get up to 100Mbps, or you may qualify for only 3Mbps. CenturyLink’s sibling Quantum Fiber service is available in very limited areas, but you’re not likely to find it if you live in the boonies.
- GigFire: Fixed wireless and fiber ISP GigFire services a chunk of far-east South Dakota, including parts of Huron, Watertown, Brookings and Madison. Fixed wireless plans for rural areas run $70 per month for 150Mbps downloads with no contracts, no data caps and Wi-Fi gear included. Standard installation is $99. GigFire has been expanding its fiber-to-the-home offerings with speeds up to 2,000Mbps, but rural residents are more likely to connect via fixed wireless.
- Interlakes Wireless: Interlakes Wireless in Chester offers a $55-per-month fixed wireless residential plan with download speeds up to 100Mbps. Data is unlimited. Installation costs $200. Service reaches Lake Madison, Lake Herman, Lake Brant and surrounding rural areas.
- Leap Communications: Leap focuses on the South Dakota plains. Fixed wireless plans range from 10 to 100Mbps at monthly prices of $45 to $115. There are no contracts or data caps. Leap has been pushing to bring fiber to its service area to provide a faster alternative to its fixed wireless network.
- Rise Broadband: Rise specializes in rural fixed wireless internet with typical download speeds ranging from 25 to 100Mbps. Speed levels will vary with your location. For example, Rise offers a $55-per-month 25Mbps plan with unlimited data to some addresses near Sioux Falls. You may be able to find a free equipment rental and installation deal.
- Santel Communications: Residents of small towns from Wolsey down to Tripp can check in with Santel for fast fiber hookups. Pricing is a bit higher than you’ll find in the cities but worthwhile for the reliability and symmetrical speeds. Plans start at $90 per month for 250Mbps and top out at $150 for 1,000Mbps. Wi-Fi gear is included.
- Venture Communications: Venture started as a telephone company focusing on rural central and northeast South Dakota. It now offers fiber internet to various small towns where you might be surprised to find such fast broadband. Prices range from $69 for 100Mbps service to $121 for 1,000Mbps. There are no data caps.
- Satellite internet: While local and regional ISPs have done a valiant job of connecting some of the more remote towns and communities in South Dakota, there are still places that may not be able to access adequate broadband from wired or fixed wireless connections. That’s where satellite from Starlink, Viasat and HughesNet comes in. Prices can be high, and speeds may be variable, but it may also be your best shot at getting online from a remote home.
Internet breakdown by city in South Dakota
It’s hard to cover the broadband options of a state like South Dakota and give individual cities the attention they deserve. That’s why we also compile lists of the best internet providers in cities across the US, including those in South Dakota. We tackle details such as internet connection types, max speeds, cheapest providers and more. Check back later if you don’t find the city you’re looking for below. We’re working to add more cities every week.
Cheap internet options in South Dakota
While Midco’s prices can vary depending on location, some customers may be able to get its $29-per-month 250Mbps plan for either cable or fiber. Starting prices vary depending on your location and any special offers that may be in effect. I recently spotted a limited-time Midco deal of $23 monthly for 250Mbps. Fiber is preferable due to the symmetrical upload speed. That’s a decent bargain for that speed level, but keep in mind that pricing will increase to $65 per month after the introductory period.
Verizon or T-Mobile phone customers can look into bundling plans to get a discount on home internet, bringing prices down as low as $35 per month with Verizon or $30 per month with T-Mobile. However, South Dakota doesn’t have the greatest 5G coverage across the state, so you may have trouble finding an open slot for 5G home internet service. South Dakotans on tight incomes should check into the federal Affordable Connectivity Program. Eligible households can get free or cheap internet through the program. Most ISPs participate.

How fast is South Dakota broadband?
South Dakota’s broadband prospects are a mixed bag. A recent Ookla speed test ranking of states placed South Dakota in the 43rd position with a median download speed of 151Mbps. That doesn’t tell the whole story, though. City dwellers are likely to have gig cable (and even 5-gig fiber in some places) as an option, but there are also quite a few small towns with fiber networks. Regional and local ISPs deliver fiber up to 5,000Mbps in some spots, including rural areas where you might not expect to find such fast connections. Golden West is an ISP to look for if you’re shopping for internet in a rural community.

What’s a good internet speed?
Most internet connection plans can now handle basic productivity and communication tasks. If you're looking for an internet plan that can accommodate videoconferencing, streaming video or gaming, you'll have a better experience with a more robust connection. Here's an overview of the recommended minimum download speeds for various applications, according to the FCC. Note that these are only guidelines -- and that internet speed, service and performance vary by connection type, provider and address.
For more information, refer to our guide on how much internet speed you really need.
- 0 to 5Mbps allows you to tackle the basics -- browsing the internet, sending and receiving email, streaming low-quality video.
- 5 to 40Mbps gives you higher-quality video streaming and videoconferencing.
- 40 to 100Mbps should give one user sufficient bandwidth to satisfy the demands of modern telecommuting, video streaming and online gaming.
- 100 to 500Mbps allows one to two users to simultaneously engage in high-bandwidth activities like videoconferencing, streaming and online gaming.
- 500 to 1,000Mbps allows three or more users to engage in high-bandwidth activities at the same time.
How CNET chose the best internet providers in South Dakota
Internet service providers are numerous and regional. Unlike the latest smartphone, laptop, router or kitchen tool, it's impractical to personally test every internet service provider in a given city. So what's our approach? For starters, we tap into a proprietary pricing, availability and speed database that draws from our own historical ISP data, partner data and mapping information from the Federal Communications Commission at FCC.gov.
But it doesn't end there. We go to the FCC's website to check our data and ensure we consider every ISP that provides service in an area. We also input local addresses on provider websites to find specific options for residents. We look at sources, including the American Customer Satisfaction Index and J.D. Power, to evaluate how happy customers are with an ISP's service. ISP plans and prices are subject to frequent changes; all information provided is accurate as of publication.
Once we have this localized information, we ask three main questions:
- Does the provider offer access to reasonably fast internet speeds?
- Do customers get decent value for what they're paying?
- Are customers happy with their service?
While the answer to those questions is often layered and complex, the providers who come closest to “yes” on all three are the ones we recommend. When selecting the cheapest internet service, we look for the plans with the lowest monthly fee, though we also factor in things like price increases, equipment fees and contracts. Choosing the fastest internet service is relatively straightforward. We look at advertised upload and download speeds and consider real-world speed data from sources like Ookla and FCC reports.

What’s the final word on internet providers in South Dakota?
Your best choice for an ISP in South Dakota depends on your location and which networks reach your home. Midco is a top contender due to its wide availability and triple-threat approach to providing cable, fiber and fixed wireless coverage. That helps it reach various places, from cities to rural districts. Pricing is reasonable, and you may luck out with a very affordable $29-per-month introductory deal. But don’t sleep on Bluepeak as an option. Like Midco, Bluepeak offers fiber up to 5,000Mbps in some areas.
Some rural and small-town residents may be able to get online via fast fiber connections, thanks to local and regional ISPs that specialize in serving those communities. Look for DSL or fixed wireless options if fiber doesn't work out. As a last resort, check into satellite internet for homes outside the coverage zones of other ISPs.
