According to CNET broadband experts, Sonic is the best internet service provider in San Francisco. It offers speeds up to 940Mbps and zero data caps for just $50 a month. But if that doesn’t persuade you, there are alternatives. Verizon 5G Home Internet, AT&T Fiber and Xfinity are widespread and varied in the area, so if you just miss Sonic’s catch area, check out these three ISPs.

For residents looking for a more affordable plan, we recommend Astound Broadband. Plans start at $30 for 300Mbps speeds, and go up to $55 for the 1,500Mbps plan (currently discounted).

For the fastest internet speeds in the city, Sonic offers up to 10,000Mbps for $50 a month. AT&T Fiber also has multi-gigabit plans of up to 5,000Mbps, while Xfinity offers a 1,200Mbps plan for $100.

Other available internet providers in San Francisco

Astound Broadband: Also known as Wave, Astound Broadband is a cable internet option available throughout San Francisco. Download speeds start at 300Mbps and top out at 1,500Mbps. Astound offers outstanding values at first glance, but all plans offer upload speeds no higher than 50Mbps, which doesn’t match fiber internet standards. Still, the pricing offers good value per megabits per second.

How many members of your household use the internet?

Google Fiber Webpass: None of the Bay Area metros are Google Fiber cities. For that, you’ll need to head south to Orange County. San Francisco and Oakland are home to scores of buildings equipped with Google Fiber Webpass. This fixed wireless service uses antennas to send a high-speed signal to multi-dwelling buildings like apartment complexes. Speeds up to a gigabit are possible at some addresses for a flat rate of $70 per month or $63 for a yearly plan.

Monkeybrains: Monkeybrains is a local provider of fixed wireless internet services operating in San Francisco since 1998. When you sign up, the company will install an antenna on the roof of your building and run an Ethernet cable into your home — plug in a router, and voila, internet access. Your speeds will depend on the strength of the signal at your address, and you shouldn’t expect anything blazing fast: advertised speeds range between 20 and 50Mbps. At a flat rate of $35 per month, Monkeybrains might be worth a call if nothing else is available.

Raw Bandwidth Communications: Raw Bandwidth utilizes a mix of internet technologies to get businesses and residential addresses online and even offers private line service with up to gigabit speeds. Residential service is available in much of San Francisco and surrounding areas, but most homes in that coverage map will have to settle for DSL or even dial-up service, making this an outdated option for Bay Area residents. Speeds won’t get any faster than 100Mbps under the best circumstances and will likely be much lower. Still, with no data caps and no prescheduled price increases, Raw Bandwidth might be a good fit for homes requiring basic connectivity for checking email and light browsing.

How fast is San Francisco broadband?

Although multiple fiber and cable providers cover the Bay Area, San Francisco’s internet speeds are relatively slow. The city ranks 72nd on Ookla’s list of the cities in the US with the fastest internet speeds, a few spots ahead of Los Angeles and Sacramento, and clocks a median download speed of 215Mbps. (Disclosure: Ookla is owned by Ziff Davis, the same parent company as CNET.)

If you’re looking for more speed than the SF average, you have many options and ISPs to choose from.

What’s a good internet speed?

Most internet connection plans can now handle basic productivity and communication tasks. If you’re looking for an internet plan that can accommodate videoconferencing, streaming video or gaming, you’ll have a better experience with a more robust connection. Here’s an overview of the recommended minimum download speeds for various applications, according to the FCC. Note that these are only guidelines and that internet speed, service and performance vary by connection type, provider and address.

How CNET chose the best internet providers in San Francisco

Internet service providers are numerous and regional. Unlike the latest smartphone, laptop, router or kitchen tool, it’s impractical to personally test every ISP in a given city. What’s our approach? We start by researching the pricing, availability and speed information, drawing on our own historical ISP data, the provider sites and mapping information from the Federal Communications Commission at FCC.gov.

It doesn’t end there: We use the FCC’s website to check our data and ensure we consider every ISP that provides service in an area. We also input local addresses on provider websites to find specific options for residents. We look at sources, including the American Customer Satisfaction Index and J.D. Power, to evaluate how happy customers are with an ISP’s service. ISP plans and prices are subject to frequent changes; all information provided is accurate as of publication.

Once we have this localized information, we ask three main questions:

  1. Does the provider offer access to reasonably fast internet speeds?
  2. Do customers get decent value for what they’re paying?
  3. Are customers happy with their service?

The answers to those questions are often layered and complex, but the providers who come closest to “yes” on all three are the ones we recommend. When selecting the cheapest internet service, we look for the plans with the lowest monthly fee, although we also factor in things like price increases, equipment fees and contracts. Choosing the fastest internet service is relatively straightforward. We look at advertised upload and download speeds and consider real-world speed data from sources like Ookla and FCC reports.

What’s the final word on internet providers in San Francisco?

If your home is wired for fiber, you’re in good shape. Along with fast speeds, fiber internet offers some of the best value in broadband, with costs per Mbps that typically fall well below what you’ll get with cable, fixed wireless, DSL or satellite. Service from Sonic costs a flat $50 per month and nets you whatever the best possible speeds are at your address, making it a tremendous value for homes with wiring capable of hitting 10Gbps. Meanwhile, AT&T is more flexible with its fiber service, allowing users to pay less for lower speeds. If fiber isn’t available at your address, sticking with a cable provider like Xfinity or Astound Broadband is your next best option.

Internet providers in San Francisco FAQ

Does San Francisco have fiber internet?

Yes. AT&T is the largest fiber internet provider in the area, with a fiber footprint covering more than a million locations. That includes multi-gig speeds of up to 5Gbps, which AT&T says are available at roughly one-third of fiber-eligible addresses in the area. Sonic offers fiber internet service at select locations in San Francisco too. Similar to AT&T, most of Sonic’s coverage map consists of slower DSL connections.

Is Google Fiber available in San Francisco?

No. Google doesn’t offer fiber internet service anywhere in the Bay Area. The company offers its Google Fiber Webpass service at select San Francisco and Oakland locations. Instead of a direct fiber connection, Webpass buildings use a special antenna to receive a high-speed internet signal over the air, with speeds up to a gigabit available in some instances.
