Rated #1 by industry standards and customers alike

We have been very happy Sonic customers for several years. When the time came to establish internet service for a new property, we did not hesitate to call Sonic. Without exception, every interaction we have had in the process has been pleasant, courteous, and effective.

We were desperate to be rid of AT&T as a service provider and made the switch to Sonic. From start to present, they have the best, most responsible customer service reps in the business. I can’t say enough great things about this company.

Hands down the best internet service in the US! 10 Gbps fiber connection for less than half price of the competitors is a steal. It’s been super reliable as well. I can’t imagine going back to any other internet provider now.
