We know the Charleston SC market

Charleston's rapid growth has brought Boeing, Volvo, and a thriving tech scene to the area. The North Charleston industrial corridor, Park Circle, and Johns Island all have distinct connectivity needs. Downtown Charleston and Mount Pleasant have strong fiber coverage from Spectrum and AT&T.

Outlying areas like Summerville, Goose Creek, and Johns Island may have more limited fiber options. Fixed wireless and Lumen serve businesses in areas where conduit-based fiber is thin. Fibi checks all options at your exact address.
