Internet Providers in Union, SC

Internet Market Overview for Union

Union is a small SC community of 8,045 residents where wired broadband options are limited. Most households rely on a single cable or DSL provider, with satellite internet (Starlink, HughesNet) and fixed wireless serving areas beyond the wired footprint. Federal BEAD funding may bring fiber infrastructure to communities like Union, though deployment timelines depend on state-level grant awards. Union's median household income of $48,197 underscores the importance of affordable broadband options in this market. ISP low-income programs and competitively priced fixed wireless plans are critical for maintaining connectivity, especially since the federal ACP subsidy program expired in June 2024. Union's housing stock is predominantly single-family homes, which gives homeowners the freedom to choose from any available ISP without building-level contracts or restrictions. This housing type also allows installation of outdoor equipment like satellite dishes and fixed wireless antennas, broadening the range of available internet options.

Union, SC is exceptionally well-served with 8 broadband providers, creating strong competition that drives down prices and incentivizes faster speeds and better service.

Union, SC has a highly concentrated broadband market (HHI: 40,513) where HughesNet dominates with 100% coverage reach — 0 percentage points ahead of the next-largest provider, Starlink at 100%. In highly concentrated markets, consumers typically see fewer promotional offers and less pressure on the leading provider to invest in network upgrades. The remaining 6 providers in Union, SC cover a fraction of addresses, limiting their competitive impact. Research from the FCC shows that markets with one dominant provider average higher monthly costs compared to markets with two or more meaningfully overlapping competitors. Fiber internet is available from 2 providers (AT&T Internet, Windstream), with 75% fiber coverage — significantly above the national average of 57%. Fiber delivers symmetrical upload and download speeds — a key advantage for households with multiple remote workers, video conference participants, or content creators who upload large files. Nationally, fiber represents the fastest-growing broadband technology segment, expanding at roughly 8 percentage points of coverage per year. Spectrum provides the primary cable broadband alternative with 87% coverage — above-average cable coverage 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 77% 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, Starlink, Viasat) provides universal coverage as a last-resort option for addresses outside wired broadband service areas. Low-Earth-orbit (LEO) satellite from Starlink has improved latency to 20-60 ms, a significant improvement over geostationary services (600+ ms), making it a practical alternative for rural households without viable fixed-line options.

Fiber-optic internet is available to only 1% of addresses in Union, SC — 56 percentage points below the national average of 57%. This significant gap reflects underinvestment in fiber infrastructure relative to the national buildout pace. Households without fiber access should evaluate cable, fixed wireless, or satellite alternatives while monitoring whether BEAD-funded fiber expansion is planned for this area. Cable broadband reaches 90% of addresses — 18 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. Fixed wireless coverage at 6% is 26 points below the national average of 32%, limiting the wireless broadband alternatives available to households outside the wired service footprint. This area has minimal fiber infrastructure. Fixed wireless (5G/LTE) and satellite (Starlink) may offer better near-term alternatives while fiber buildout gradually expands to underserved markets.

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.
