Fiber internet is available from 3 providers (CenturyLink, Rise Broadband, AT&T Internet), with 70% 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.

Fixed wireless internet — including 5G home internet services — is available from Rise Broadband and T-Mobile, reaching 54% 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 (Viasat, HughesNet, Starlink) 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.

The South Dakota GOED Broadband 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.
