As anyone who lives here knows, South Dakota is a largely agricultural state, so much so that driving through can feel like a journey through one big farm. In fact, cattle outnumber humans in South Dakota 4:1.
The gently rolling terrain that characterizes South Dakota spells good things for cell phone coverage, since it means there are a minimum of geographical features, like mountains, to get in the way of cell signals as they travel from towers to phones.
The 4G coverage percentages in South Dakota speak to this, as both Verizon and AT&T blanket nearly the entirety of the state with their networks. Carrier 5G coverage, meanwhile, is steadily improving, with AT&T currently offering the most service statewide.
There’s far more nuance to the cell phone coverage picture in South Dakota than any of this would suggest, however, so read on to learn the ins and outs of getting the best cell phone coverage in South Dakota.
Verizon offers the second-most 4G LTE coverage, and the third-most 5G coverage, in South Dakota.
Verizon wields a formidable 4G network in South Dakota, covering an impressive 85% of the state, second only to AT&T. That makes Verizon a safe choice if you’re looking for a carrier that offers wide-reaching and reliable coverage in South Dakota.
Verizon’s 5G network is quite limited in South Dakota, spreading to just 4% of the state (most of it around Sioux Falls, Rapid City, and Pierre).
That said, the carrier is actively expanding its network reach in the state, so you can expect this percentage—and the availability of the carrier’s fastest network speeds—to increase in the coming weeks and months.
AT&T delivers excellent 4G and 5G service availability throughout the state of South Dakota.
AT&T’s 4G network covers 90% of South Dakota’s 77,047 square miles, a truly impressive stat when you consider how much of the state is rural and hard to get to. If you’re looking for a carrier that delivers a reliable signal almost everywhere in South Dakota, going with AT&T is a smart move.
AT&T wields the most second-most wide-reaching 5G network in South Dakota, covering 51% of the state.
AT&T’s 5G network is present in all of South Dakota’s foremost towns and cities, and many of its less populated areas as well. Better yet, a portion of this coverage is made up of the carrier’s so-called 5G+ spectrum, which delivers super-fast speeds, low latency times, and enhanced reliability.
T-Mobile serves up the most 5G coverage, and the third-most 4G coverage, in South Dakota.
T-Mobile’s 4G network spans 54% of South Dakota, which is decidedly less than both Verizon and AT&T (covering 90% and 85% of the state respectively). That said, your town may very well be covered by T-Mobile’s 4G—use the map above to find out.
T-Mobile offers the most 5G coverage in South Dakota, covering 18% of the state. Fortunately, a good portion of this 5G coverage is made up of the carrier’s 5G Ultra Capacity network, which delivers incredibly fast speeds for latency-free browsing, streaming, and gaming.
While we’ve outlined cell phone coverage from the three major U.S. cell phone carriers, it’s important to know that you aren’t limited to these companies if you need cell phone service in South Dakota. A variety of smaller carriers, or MVNOs, also operate in the state, allowing you to sign up for equivalent plans, with similar coverage, for less than you’d otherwise pay.
All of these carriers lease from the aforementioned major carrier networks to provide coverage to their customers. If you’re signed up with Spectrum Mobile, for example, you’ll have access to Verizon coverage, since the carrier runs on that network. Here are some popular MVNOs, and the networks they operate on:
When it comes to cell phone coverage, you don’t just need a cellular signal—you need that signal to provide adequate speed. That’s why it’s important to distinguish between 4G and 5G coverage in your area. In general, 5G provides faster speeds and greater reliability than 4G. However, that’s not always the case, as there may be instances when the speeds of these respective coverage types are actually quite similar.
There’s more to getting the best coverage than just signing up with the carrier that offers reliable service in the places you spend time. These include:
AT&T offers the best 4G coverage in South Dakota, while T-Mobile delivers the most 5G coverage.
