In highly concentrated markets, consumers typically see fewer promotional offers and less pressure on the leading provider to invest in network upgrades. The remaining 7 providers in Mount Pleasant, SC cover a fraction of addresses, limiting their competitive impact.

Fiber internet is available from 3 providers (Xfinity, AT&T Internet, WOW! Internet), with 69% fiber coverage — significantly above the national average of 57%.

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 69% 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 internet — including 5G home internet services — is available from T-Mobile and AT&T Internet, reaching 69% of addresses (well above the national fixed wireless average of 32%). 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 (HughesNet, Viasat, 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.
Fiber-optic availability at 55% is slightly below the national figure of 57%. The gap is modest, and ongoing FTTH expansion from national and regional carriers may close it within the next 1-2 years. Residents should check availability at their specific address, as fiber buildout often progresses neighborhood by neighborhood. Cable broadband reaches 99% of addresses — 27 points above the national cable average of 72%. Strong cable coverage ensures most households have access to speeds of 100 Mbps or higher, making cable a reliable fallback even where fiber has not yet arrived.

Nationally, fiber availability has expanded by roughly 8 percentage points per year since 2022, with ISPs like AT&T, Frontier, and Google Fiber leading the rollout of high-speed internet.
