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.

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.
