Picking a Provider

Sonic is a great balance of price and speed, but it does not offer the same availability and options as AT&T. Check out which user each provider is best suited for you based on their offerings.

Sonic: High-Speed User

Sonic is an excellent choice for fast, affordable internet. The only caveat is that you need to be a California resident. Sonic’s availability spans across San Francisco Bay Area, Sacramento, and Los Angeles. However, if you do live in or near these metro areas, you can get speeds up to 10 Gbps. The possibilities are just about endless with that kind of range. Plus, you’ll have access to personalized, local customer support if you run into any issues.

AT&T: Heavy User

AT&T offers fast, symmetrical upload and download speeds, which is ideal for those who stream frequently, game online, or work from home. It’s also an excellent option for households that need multiple simultaneous device connections. As one of the nation’s top providers, AT&T offers many TV and internet bundles to help customers save. Enjoy fast, reliable speeds with the option to add budget-friendly services to create the entertainment suite you’ve always wanted.
