What is the best internet provider in South Carolina?

For folks in South Carolina, Spectrum is CNET's pick for the best internet provider, due to its widespread availability throughout the state, fast speeds and customer-friendly service terms. More than a million and a half South Carolina homes are serviceable for Spectrum internet, according to the Federal Communications Commission, and download speeds up to 1,000Mbps are available throughout all service areas.

AT&T also has a large presence in the Palmetto State and may prove to be the better choice for speed and overall value, particularly if a fiber-optic connection is available at your address. Other national ISPs, including Xfinity, Kinetic and WideOpenWest, also serve South Carolina and are worth considering along with the many regional providers that offer service throughout the state.

As a lifelong resident of the Carolinas, I know firsthand the benefits of living in South Carolina. We've got some of the lowest taxes in the South, the best beaches on the East Coast and the top schools in academics and athletics in the nation. Internet service can be decent too, depending on where you live in the state. You'll find my picks for the best internet providers in South Carolina below, followed by recommendations for cheap and fast internet plans in the state.

An overview of other South Carolina ISPs

AT&T Internet: AT&T’s copper-based service has a broader customer base in South Carolina than AT&T Fiber, but speeds are slower for the same starting price. Consider it if no other wired connection types are available at your address.

Comporium: Primarily a cable provider with some fiber-to-the-home mixed in, Comporium serves Rock Hill and Lancaster along with select areas north of Spartanburg and west of Columbia. Pricing and speeds are on par with other local providers. I have Comporium, and I have no complaints.

Horry Telephone Cooperative: The go-to for fiber internet in Myrtle Beach. HTC offers fast, symmetrical speeds (500Mbps, 750Mbps and 1Gbps) at reasonable rates. Check them out if you’re moving to or around the Grand Strand. 

Kinetic by Windstream: You’ll find Kinetic service around Lexington, Kershaw, Saint Matthews and in the northwesternmost part of the state. The fiber service is preferred, but DSL is also a decent option, with rural internet speeds faster than most. 

Starlink: Like other satellite internet services, Starlink is available throughout South Carolina. Unlike other satellite internet services, speeds can reach up to 200Mbps or higher and latency is estimated to be much lower at 25 to 60ms or over 100ms in “certain remote locations,” according to Starlink’s service description.

Verizon 5G Home Internet: Verizon’s home internet service advertises faster maximum speeds than T-Mobile for around the same monthly price ($50 for 50-300Mbps, $70 for 85-1,000Mbps), but service is currently limited to parts of Columbia and Greenville.

Viasat: Satellite internet from Viasat is a bit more expensive than Hughesnet, but you may get faster speeds and a higher monthly data allowance for the extra cost. Compare Hughesnet and Viasat plans closely if satellite service is your only broadband option.

West Carolina Rural Telephone: Serving the Clemson/Seneca area and communities along the Georgia border down to Augusta, West Carolina Tel offers fiber-optic service with speeds ranging from 250Mbps to 1Gbps for $50 to $80 per month with no contracts or data caps.

WideOpenWest: A leader in low introductory pricing, WideOpenWest adds some cable internet competition to the Charleston and Mount Pleasant areas.

What’s the best rural internet in South Carolina?

I’ve driven 77 and 85 (and Highway 521 down past Lancaster and Highway 9 to the beach) enough times to know South Carolina has some beautiful but remote areas. What’s the best way to get internet in these rural areas? 

5G home internet: T-Mobile’s home internet service covers many South Carolina households, according to the FCC. 5G may not be available to the entire coverage area (T-Mobile still relies on its 4G LTE network sometimes), but the potential speeds, pricing and service terms could be the best you’ll find in rural areas.

DSL: AT&T and Kinetic are the main DSL providers in South Carolina. Speeds are slower than you’d get with cable or fiber internet, but DSL may serve as a workable broadband solution in rural areas where such connections are unavailable. 

Satellite internet: It’s nearly always an option wherever you are, but satellite internet speeds are low while data caps and prices are high compared to other types of internet. I’d recommend exploring other potential options before settling on satellite service.

South Carolina internet speeds

Broadband speeds, defined as at least 100Mbps down and 20Mbps up, are available to 100% of South Carolina households, according to the FCC. Satellite internet inflates that number a bit as only 90% can get those speeds over a wired connection such as DSL, cable or fiber. Faster speeds are available to most residents with 89% of the state eligible for download speeds of 250Mbps or higher and upload speeds of 25Mbps or higher. 

Recent Ookla speed test data ranks South Carolina 16th among US States for the fastest median download speeds at 224Mbps. That’s lower than the national average (254Mbps) and our northern neighbor (North Carolina clocked 231Mbps, good for seventh overall), but faster than nearby Georgia (188Mbps, 38th). 

What are the fastest internet plans in South Carolina?

A fiber internet connection will be your best bet for fast speeds in South Carolina and comes with the added advantage of symmetrical (or close) download and upload speeds. Cable internet from providers such as Comporium, Spectrum, Xfinity and WOW is still plenty fast, but expect slower upload speeds ranging from 10 to 50Mbps. Cable internet can also be more susceptible to slowed speeds due to network congestion during peak usage times.

How CNET chose the best internet providers in South Carolina

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. What's our approach? For starters, we tap into a proprietary database of pricing, availability and speed information that draws from our own historical ISP data, partner data and mapping information from the Federal Communications Commission at FCC.gov. 

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, although 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 Carolina?

Spectrum is CNET’s pick for the best internet provider in South Carolina due to its high availability, fast speeds and favorable service terms like low equipment fees and unlimited data. 

AT&T Fiber, T-Mobile Home Internet and Xfinity, along with regional providers like Comporium, HTC and WCTel, may be the best ISPs for your home, depending on your needs and your location.

Those in rural areas may want to consider DSL from AT&T or Kinetic and 5G from T-Mobile before resorting to satellite internet. If no such connections are available, look to Hughesnet, Viasat or satellite newcomer Starlink for home internet service.
