How We Found the Best Internet Providers in San Francisco

We analyzed a dozen companies to find the best internet providers in San Francisco. Some of the key features we looked for are:

  • Coverage: The finalists in our San Francisco broadband review offered good coverage for the area. This was the most important factor, so you can rest assured the plans and offers are likely available for your area.
  • Value. You often get what you pay for. The cheapest broadband provider may not be the most convenient. We looked over many provider’s offerings in search of speeds, data caps, contract lengths, packages offered and equipment costs to determine which internet providers in San Francisco provide customers the best value.
  • Customer Satisfaction. At Reviews.com, satisfaction ratings from the American Customer Satisfaction Index (ACSI) and J.D. Power are an important part of the decision-making process on which services and products are the best. Broadband service provider ratings are mediocre across the board, so analyzing each internet provider individually and comparing them to industry averages gives us a better idea of how they respond to customer issues.

San Francisco Internet FAQ

How Much Speed Do I Need to Stream Movies and for Online Gaming?

Streaming movies and downloading games can take up a lot of bandwidth. And if you have several household members on multiple devices, the higher the speed you can afford, the better the streaming. Aim for a service plan of 1000 Mbps if you don’t want to experience lag while streaming.

How Fast is Internet Service in San Francisco?

If you’re moving to San Francisco, you’re in luck. You’ll have access to several providers offering 1000 Mbps (1 Gbps) service.

Is Fiber Internet Faster than Broadband Cable?

Yes, fiber is the fastest option of the two. The reason being the wiring that carries the internet into your home. Fiber optic internet is delivered on a dedicated line straight to you. Broadband cable wires are shared with anyone signed up for the service in your area, which can create a slowdown in speeds if several users in the neighborhood are online at the same time.
