Fiber Internet Providers San Francisco
San Francisco has strong fiber coverage compared to most U.S. cities, with AT&T Fiber and Sonic both offering true fiber-to-the-home (FTTH) service across many neighborhoods. AT&T Fiber is available in much of the city and has been the fastest-growing fiber option in recent years, with symmetric speeds starting at 300 Mbps and going up to 5 Gbps. Sonic, headquartered in the Bay Area, provides competitive symmetric gigabit service and is particularly well-regarded for its transparent pricing and no-data-cap policy.
Neighborhoods with strong fiber availability include the Castro, Noe Valley, Mission District, SoMa, Pacific Heights, Marina, and the Inner Richmond and Inner Sunset. Build-out in the Outer Sunset, Excelsior, Ingleside, and Visitacion Valley has accelerated, though some pockets in these areas remain cable-only. Bayview-Hunters Point and parts of the southern neighborhoods have seen growing investment tied to digital equity initiatives. If fiber isn’t yet live at your specific address, AT&T’s rollout tracker and Sonic’s waitlist are good resources to monitor
