Best Internet Providers in Charleston, SC
The best internet providers in Charleston are AT&T Fiber, Xfinity and WOW! AT&T Fiber is the best option of the three because it delivers symmetrical download and upload speeds up to 5 Gbps. They’re also known for offering contract-free plans without data caps, which are an ideal choice for large households with power internet users. AT&T’s fast speeds and strong customer satisfaction have made the provider a favorite among users. In J.D. Power’s 2024 U.S. Residential Internet Service Provider Satisfaction Study, AT&T secured the highest ranking in the North Central and West regions. Charleston residents who live in AT&T Fiber’s coverage areas can sign up for internet-only plans that start as low as $55 per month.
Xfinity is the next-best internet provider in Charleston, with cable internet plans that start at $30 per month. Similar to AT&T Fiber, Xfinity provides bundle deals for internet, TV and mobile services. Xfinity offers exclusive promotions, such as a free Xfinity Mobile Unlimited line, a free Getting Started kit and free shipping to both new and existing customers. Between AT&T Fiber and Xfinity, the latter offers more accessibility for Charleston residents. Xfinity speeds are also worth considering, especially since they can reach as high as 1 Gbps.
WOW! is another cable internet provider in the city, providing download speeds up to 1 Gbps. Customers who sign up for WOW! internet plans can get a free self-install kit, adding to their overall savings. WOW! also offers limited-time promotions for new customers such as Visa Rewards Cards and discounts on bundles. Their plans are reasonably priced, with the cheapest plans starting at $25 per month.
Fastest Internet Providers in Charleston, SC
AT&T is the fastest provider in Charleston, with speeds up to 5 Gbps.
The fastest internet providers in Charleston are AT&T Fiber, Xfinity and WOW! AT&T Fiber delivers symmetrical speeds because it operates on a fiber network that transmits data faster over longer distances than other wired connections such as DSL and cable. They also don’t have data caps to tamper with their performance, making AT&T Fiber ideal for streamers and gamers.
Xfinity is the second-fastest internet provider in Charleston. With download speeds up to 1 Gbps on a cable connection, Xfinity provides vast coverage across Charleston at a small cost of internet speeds. They’re the next best option if fiber internet is unavailable in your neighborhood. Xfinity does impose a data cap on plans, though it’s generous and unlikely that casual users will hit their cap often.
Lastly, WOW! is another contender for fast internet in Charleston, with download speeds that go up to 1 Gbps. Like Xfinity, WOW! is a cable internet provider, which means it doesn’t have symmetrical speeds. However, the provider is a great alternative if neither AT&T Fiber nor Xfinity are available and you’re looking for gigabit speeds over a wired connection.

Internet Availability in Charleston, SC
Charleston residents can choose from 12 providers to access a reliable internet connection, but how do you know which one will work for your home? The Holy City features top providers for both fiber and cable services, with Xfinity featuring the widest availability covering 93.3% of the city.
AT&T Fiber features sporadic coverage across the inlet of the Ashley River, covering 38.9% of the city. Residents located near Whitehouse Plantation and Stiles Point can access the provider’s fiber service too. Foley Beach and Sullivan’s Island lack coverage near the shoreline, as do inland locations, such as Cherokee Place and the Charleston Air Force Base.
Xfinity’s cable internet fills in more than enough gaps in AT&T Fiber’s coverage. With coverage on Foley Beach and plenty of service near the Air Force Base, unlike AT&T Fiber, the provider boasts sweeping availability from the shoreline to Weatherstone. Unfortunately, service in Long Island, Goat Island, and along Lighthouse Creek is unavailable.
Another cable provider in Charleston worth mentioning is WOW! While the provider only covers 58.8% of the city, it features strong coverage to homes on the northeast of the Stono River and both sides of the Ashley River.
