Fiber considerations
AT&T Fiber and Sonic report fiber service in San Francisco. Check the exact address because neither provider's city page establishes universal citywide availability.
Review fiber providers →San Francisco Internet Providers
San Francisco has a mix of fiber, cable, and fixed-wireless home internet. AT&T Fiber, Sonic, Xfinity, Astound Broadband, EarthLink, Verizon 5G Home Internet, and T-Mobile Home Internet all have current San Francisco service or availability evidence, but the options at a particular home can differ.

Check internet availability at your address
A ZIP code is a useful starting point, but provider networks are reported at individual locations. Use your service address when the provider offers an address-level checker.
Prices, speeds, promotions, equipment, installation terms and availability can change. Confirm the final offer directly with the provider.

San Francisco internet guide
Start with the connection, then compare the plan
The meaningful differences in San Francisco are not limited to advertised download speed. Fiber can provide symmetrical service, cable can provide high download capacity, and 5G home internet can avoid a traditional wired installation.
Apartment buildings
In a dense multi-unit market, the serviceable location and the building itself matter. A provider's network footprint does not by itself prove that every unit can be ordered.
See the local context →Remote work
For frequent video meetings and large uploads, compare upload speed and latency as well as download speed. Symmetrical fiber plans can materially change the upload side of the connection.
Compare technologies →Total monthly cost
Introductory rates are only one part of the bill. Check the regular rate, equipment, installation, taxes, promotional requirements and any building- specific terms before ordering.

Internet providers serving San Francisco
This table separates the technology and advertised capability from the question of whether that service can actually be ordered at a particular address.
Research note:
The FCC National Broadband Map is location-based and reports
provider-submitted availability, technology, and maximum advertised
speeds. Provider sites remain the final check for an orderable service address.

San Francisco speed guide
Check your address
How much internet speed do you need?
A higher advertised speed is not automatically a better fit. Household size, simultaneous use, upload needs, Wi-Fi equipment and the quality of the building's internal network can matter just as much.
Check your address
100–300 Mbps
Light to moderate use
Browsing, email, video calls, HD streaming and ordinary connected devices.
300–500 Mbps
Multiple users
Several simultaneous streams, remote work, gaming and routine cloud use.
500–1,000 Mbps
Heavy household use
Frequent large downloads, 4K streaming, gaming, uploads and many simultaneous users.
1–3 Gbps
Multi-gig households
Large transfers, multiple power users and home networks with multi-gig hardware.
5+ Gbps
Specialized use
Advanced home labs, creators and several simultaneous users with compatible wired equipment.
Connection types
Fiber vs. cable vs. 5G home internet in San Francisco
The technology behind the service affects upload capacity, latency, installation requirements and how availability should be checked.
Fiber internet
Fiber uses optical infrastructure and can provide high download and upload capacity. AT&T and Sonic both publish San Francisco fiber availability, with address checks required.
Cable and fiber-powered wired service
Xfinity and Astound provide wired broadband in the San Francisco/Bay Area market. Astound states that delivery can use coaxial cable or fiber depending on location.
5G home internet
Verizon and T-Mobile provide fixed-wireless home internet over cellular networks. Eligibility is separate from ordinary mobile coverage and should be checked at the service address.
San Francisco internet market
Why address-level research matters in San Francisco
The FCC's broadband map treats individual buildings as serviceable locations. Provider tools can also identify building agreements or address-specific offers. That makes a citywide provider list useful for research, but insufficient for a final availability decision.
Multi-unit buildings
Apartment and condominium residents may have a different set of orderable services from a nearby single-family address. Astound's service checker, for example, can identify building-agreement conditions.
Fiber is not automatically citywide
AT&T explicitly describes its San Francisco fiber service as available in parts of the city, while Sonic's local page requires an address lookup. A provider's presence in San Francisco should not be converted into a claim about every block.
City connectivity programs
San Francisco has also invested in digital inclusion and Fiber to Housing. City technology materials report that more than 20,000 affordable-housing units had access to high-speed internet, showing that the local broadband story includes public connectivity programs as well as retail ISP networks.
How to verify:
Search the exact location in the FCC National Broadband Map, then use the provider's
own address checker. The FCC says its fixed map reports provider-submitted availability
at individual locations and can show technology plus maximum advertised download and
upload speeds.
Greater San Francisco Bay Area
Nearby cities and Bay Area communities
San Francisco is part of a larger Bay Area broadband market. Nearby cities can have different wired networks, fiber deployments, cable footprints and fixed-wireless availability. A provider serving San Francisco should not automatically be assumed to serve every surrounding community or building.
Oakland
Oakland is directly east of San Francisco across the Bay. Its residential broadband market should be researched separately because provider footprints and network technologies can differ between Oakland and San Francisco.
Oakland Internet Providers →Daly City
Daly City borders San Francisco to the south and is part of the same densely developed regional market. Internet availability can still change by street, building and service address.
Daly City Internet Providers →South San Francisco
South San Francisco is south of the city near the Peninsula corridor. Its broadband options should be checked using South San Francisco-specific provider information rather than assuming San Francisco coverage continues across the city boundary.
South San Francisco Internet Providers →San Bruno
San Bruno is on the Peninsula south of San Francisco. Fiber, cable and other residential internet options can vary from nearby San Francisco addresses, making an address-level check important.
San Bruno Internet Providers →Pacifica
Pacifica is a coastal community immediately south of San Francisco. Local terrain and network construction can make provider availability more address-specific than a simple citywide coverage statement suggests.
Pacifica Internet Providers →Brisbane
Brisbane is just south of San Francisco near the southeastern edge of the city. Its close proximity to San Francisco does not establish that every provider available in the city serves every Brisbane address.
Brisbane Internet Providers →San Mateo
San Mateo is farther south on the Peninsula and has a separate residential broadband market. Provider availability should be verified against the actual San Mateo service address.
San Mateo Internet Providers →Millbrae
Millbrae is south of San Francisco near the San Francisco International Airport area. Broadband choices can differ from nearby cities, particularly where wired network boundaries meet.
Millbrae Internet Providers →Berkeley
Berkeley is east of San Francisco across the Bay and has its own residential broadband footprint. Provider and technology availability should be checked using the Berkeley address rather than a San Francisco listing.
Berkeley Internet Providers →Alameda
Alameda is an island city in the East Bay. Its geographic separation from San Francisco and Oakland makes address-level verification particularly important when comparing local wired and wireless options.
Alameda Internet Providers →Richmond
Richmond is north of Berkeley along the East Bay. Its broadband market should be evaluated independently because provider footprints and available technologies can change across municipal boundaries.
Richmond Internet Providers →Sausalito
Sausalito is across the Golden Gate Bridge in Marin County. Its smaller residential market and separate municipal service area mean San Francisco provider availability should not be assumed to extend to every address there.

San Francisco internet FAQ
Frequently asked questions about San Francisco broadband
These answers focus on availability, technology and the differences between citywide research and an address-level service decision.
What internet providers are available in San Francisco?
Current provider evidence reviewed for this page includes AT&T Fiber, Sonic,
Xfinity, Astound Broadband, EarthLink, Verizon 5G Home Internet and T-Mobile Home
Internet. The exact set of orderable services depends on the address.
Is fiber internet available in San Francisco?
Yes. AT&T and Sonic both publish San Francisco fiber service information.
AT&T says its fiber service is available in parts of San Francisco, while Sonic
provides a San Francisco-specific address checker. Availability should be confirmed
for the exact property.
What is the fastest internet available in San Francisco?
The answer depends on the address. Sonic currently advertises fiber service up to
10 Gbps in San Francisco. AT&T advertises up to 5 Gbps where available, and
other providers also advertise gigabit or multi-gigabit tiers. These maximums do
not mean the same speed is offered at every address.
How much does internet cost in San Francisco?
Prices vary by provider, plan, address, promotion, autopay requirements, equipment,
taxes and installation terms. Because introductory offers change frequently, compare
the current broadband label or provider checkout page for the exact address rather
than relying on a citywide starting price.
Does internet availability vary by San Francisco neighborhood?
Yes. The FCC National Broadband Map reports fixed broadband availability at individual
locations, and provider checkers can also require the exact street address or unit.
Neighborhood names are useful for geography but are not reliable service boundaries.
Is fiber better for remote work and uploads?
Fiber can provide substantially higher upload capacity and symmetrical service than
many cable plans. For households that frequently upload large files or rely heavily
on two-way video and cloud applications, upload performance is worth comparing rather
than looking only at download speed.
Is 5G home internet the same as 5G mobile coverage?
No. The FCC distinguishes mobile coverage from fixed broadband availability, and
providers can require a separate home-internet eligibility check. A strong mobile
signal at a location does not by itself establish that a home internet plan can be
ordered there.
Does San Francisco have public or affordable broadband programs?
Yes. San Francisco has digital-equity initiatives that include Fiber to Housing and
other connectivity programs. City technology materials report more than 20,000
affordable-housing units with access to high-speed internet. These programs are
distinct from commercial retail ISP availability.
Is Sonic available in San Francisco?
Yes. Sonic maintains a San Francisco-specific internet page and an address-level
availability checker. Sonic describes its San Francisco network as 10-Gigabit fiber,
but the actual service tier depends on the address.
Is Xfinity available throughout San Francisco?
Xfinity has a San Francisco service page and local stores, but its own page says
availability, speeds and pricing vary by location. Use the provider's address
checker for the property you are evaluating.
Pricing & availability disclosure: Internet plans, advertised speeds, promotional pricing, equipment charges, installation fees and availability can change. Provider marketing pages describe maximum or advertised capabilities, not guaranteed performance at every address. This page is for research and comparison; confirm the provider's current broadband label, terms and final price before ordering.
