Nationally, fiber represents the fastest-growing broadband technology segment, expanding at roughly 8 percentage points of coverage per year. Xfinity provides the primary cable broadband alternative with 77% coverage — cable coverage in line with the national average of 72%. Cable internet uses DOCSIS 3.1 technology to deliver download speeds of 100 Mbps to 1.2 Gbps, though upload speeds (typically 10-35 Mbps) lag behind fiber's symmetrical performance. For households that do not require heavy upstream bandwidth, cable plans often offer competitive pricing to fiber.

Fixed wireless offers a no-installation alternative that is increasingly competitive with cable for everyday internet use, with speeds typically ranging from 50-300 Mbps download. Unlike satellite, fixed wireless delivers lower latency (20-40 ms), making it viable for video conferencing and gaming. Satellite internet (Viasat, HughesNet, Starlink) reaches addresses that wired broadband can't. Starlink's low-Earth-orbit (LEO) technology delivers 20-60 ms latency — a major improvement over geostationary services at 600+ ms — making it a practical choice for rural households without fixed-line options.

Residents of ZIP code 29829 can choose from plans starting at $30/mo (Xfinity Gigabit Extra, 1.3 Gbps download) up to 1.3 Gbps (Xfinity Gigabit Extra at $30/mo).

South Carolina received $920 million in federal BEAD funding. The South Carolina Broadband Office is currently in the challenge phase, which means providers and communities can dispute the FCC broadband maps that determine which locations qualify for funding — a critical step before deployment grants are awarded. The Affordable Connectivity Program (ACP) previously provided up to $30/month subsidies for eligible households, though federal funding expired in 2024. Some providers continue offering voluntary low-income discounts.
