Sonic also provides fiber internet, primarily in the suburbs of San Francisco, Daly City, Berkeley, San Mateo, its surrounding neighborhoods, and parts of Sacramento and Santa Rosa. Sonic’s IP Broadband also comes with Voice-Over-IP (VoIP) phone service.

Like most providers, Sonic’s advertised speeds (up to 1 Gbps) are not precisely what you will always receive. Still, Sonic is one of the fastest internet providers in California. Our Sonic internet users experience average download speeds comparable to many major fiber providers like Verizon Fios and AT&T Fiber.
