Top Factors to Consider When Shopping for Internet Service in San Francisco
The benefit of cable is that it generally has better speeds and offers good bundle deals if you also want TV service. The main cable provider in San Fran is Comcast Xfinity, along with their X1 TV platform.
DSL is often seen as the second choice due to the older phone-line infrastructure it travels on. However, it can get the upper hand on cable in some cases depending on your distance from the local provider office. It also offers a dedicated line vs the shared bandwidth cable offers within neighborhoods, so you’ll see less slowdown during peak use hours when everyone starts streaming Netflix in the evening.
Regardless of whether you choose cable or DSL, you need to watch out for data caps and equipment rental fees.
Comcast, the main cable provider in San Francisco, set a 1 Terabyte limit on data usage for residential customers as of 2017.
Considering that the average home Internet subscriber only uses a fraction of that, it’s not always worth worrying about. It can become problematic, however, if you stream video throughout the day on a daily basis, are a frequent gamer/Twitch user, or generally use your Internet connection much more than the average person.
Unfortunately, data caps are quickly becoming standard practice for cable providers. The important thing for San Fran Internet users is to understand what they are. Know what your cap is before you subscribe to an Internet plan. If you watch a lot of TV, consider getting a dedicated TV plan to avoid paying overage fees from streaming beyond your data allowance.
Equipment Rental Fees
Another common feature among San Fran DSL and cable companies is the “equipment rental fee.” Every home Internet plan will require some hardware on your end to deliver the connection and Wi-Fi to your apartment. (Modem, router, and our “gateway” device.)
It has become common for providers to charge an additional $5+/month for including the hardware with your plan. This usually includes installation by a trained tech from the provider. While this is a good deal if you can’t face the technical challenge of installing yourself, it’s a bad deal if you want to save money in the long term.
Considering that the average modem/router combo only costs $40–100 to buy outright from a third party like Amazon, you’ll recoup the upfront cost within the year. After that, you’ll save hundreds annually for the length of your service from that company.

Will San Francisco Get Municipal Broadband?
Since Google Fiber put the brakes on Internet service in San Francisco, the city has been moving ahead with conversations to utilize the same dark fiber networks that interested Google for publicly-owned “municipal broadband” service. This plan is still in the formative stages. San Francisco’s government is notoriously slow-moving and divided when it comes to local infrastructure, so it may be some time before municipal broadband is a reality — if ever.
Low-Income Internet in San Fran
There are a variety of public and private programs in the San Francisco to help bridge the “digital divide” for low-income residents. Basic home access can be installed for as low as $10/month, and public training programs take place regularly to help educate newcomers to computer services. Public libraries in the area also offer free Wi-Fi and affordable digital services like printing and scanning.
