Sonic may be available only in California, but it’s among the Top 15 largest DSL providers in the U.S. Sonic’s DSL internet service is available to over 8.9 million people. Some subscribers in Sonic’s DSL coverage area can receive Fusion IP Broadband, which uses AT&T’s network to deliver high speeds along with Sonic’s unique features.

That said, Sonic’s main draw is its fiber internet connection. Sonic primarily serves San Francisco, Daly City, Berkeley, San Mateo, its surrounding neighborhoods, as well as parts of Sacramento and Santa Rosa. Sonic’s IP Broadband also comes with Voice-Over-IP (VoIP) phone service.
