Fastest Internet Providers in San Francisco, CA

Sonic is the fastest provider in San Francisco, with speeds up to 10 Gbps.

The fastest of San Francisco’s internet service companies is AT&T Internet. With the top plan available in the city, you could get speeds of up to 10 Gbps.

For the best and most reliable performance, we recommend going with a fiber internet provider. Fiber internet connections offer faster upload speeds than their DSL and cable counterparts — unlike DSL or cable connections, fiber connections provide upload speeds that are just as fast as their download speeds.

When you’re considering speeds as you shop for internet plans in San Francisco, you should also take data caps into account. Most fiber internet providers you come across will include unlimited data with their plans, but cable internet providers tend to employ a data cap. This is where household size and user types are important factors when finding an internet plan that suits your needs. If you live in a single household and don’t engage in online activities every day, then a data cap might not affect your experience. However, if you live in a large household with multiple power internet users, then an internet plan with unlimited data is the better choice.

Internet Availability in San Francisco, CA

As you’d expect from a tech hub, San Francisco is very well served by broadband internet companies. That starts with the region’s cable provider, Xfinity, which offers service at virtually every address in the city. Xfinity is a major player in San Francisco — if you’re at work downtown or using the free Wi-Fi at a coffee shop near the Presidio, there’s a good chance that you’re using Xfinity internet.

Getting AT&T Fiber, however, will depend a bit more on your area. You’ll likely be able to sign up for AT&T Fiber if you live in the Richmond District between the Presidio and Golden Gate Park. Coverage is also pretty solid south of Golden Gate Park in the Sunset District, though it drops off a bit as you reach Parkside. AT&T Fiber also serves Noe Valley, the southern part of Westwood Park, just about all of the Excelsior District, and a good chunk of the Bayview District. But in the Mission, the Haight, and the Tenderloin, AT&T Fiber’s availability gets spottier. In downtown San Francisco, there’s not much availability at all.

If you can’t get AT&T Fiber in your area of San Francisco, you may be able to get fiber internet through Sonic, which has been expanding its footprint in the city in recent years.
