Internet Availability in Charleston, SC
Charleston residents can choose from 10 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.
