The 30-Second Verdict
UpdatedXfinity is the best overall, with cable speeds up to 2,000 Mbps reaching about 40% of the city, while its overall footprint reaches about 98%. If Sonic.net reaches your address, it is the faster choice, with fiber speeds up to 10,000/10,000 Mbps reaching about 8% of the city. Where Xfinity does not reach, AT&T is the safe backup, mostly DSL, with an overall footprint of about 98% and its fastest common DSL tier, up to 100 Mbps, reaching about 28%.
Local results vary sharply: Xfinity leads around the University of San Francisco in ZIP 94117 and San Francisco State University in ZIP 94132, while Sonic.net is especially strong in the Mission District, ZIP 94110. Fiber is genuinely available in ZIP 94105, where AT&T reaches about 26% with up to 5,000/5,000 Mbps, and Astound Broadband reaches about 16% with up to 1,500/1,500 Mbps. Students should check apartment wiring carefully, since some buildings may still be stuck with older DSL or copper, even when nearby addresses have fiber, and reliable service matters for Zoom, streaming, and gaming. Unwired Ltd, T-Mobile, and Verizon are worth checking for fixed wireless, but coverage can change street by street, so confirm the exact address before choosing.

About AT&T
At $35 to $90 per month, AT&T offers strong value through fiber, including up to 5,000 Mbps both ways on its $90 5 GIG plan and up to 1,000 Mbps both ways for $50, though the fastest fiber option reaches about 30% of San Francisco and the 1 GIG and 300Mbps plans reach about 38%.

THE TAKEAWAY
Our recommendation for San Francisco
Up to 200 Mbps download and 25 Mbps upload, with a 59/100 Speed Score, should handle everyday browsing, streaming, and video calls, but it is below San Francisco’s 69 average. This fixed wireless service offers adequate performance, though fixed wireless can be less consistent than cable or fiber, so consider checking other providers first for demanding or latency-sensitive use. The plan is listed as available to 92.2% of San Francisco, but availability and performance still depend on your specific address.

About Unwired Ltd
Up to 200 Mbps download and 25 Mbps upload should handle streaming, video calls, gaming, and a typical connected household, making Unwired Ltd a practical but not top-tier choice. Its fixed-wireless plan is available across 92.2% of San Francisco, but performance can vary by address, so check for faster fiber or cable service first if you need consistently strong speeds for a busy household.

Satellite internet can handle everyday browsing, streaming, and many work-from-home needs, but its higher latency may be noticeable for competitive gaming and other real-time applications. Starlink’s Residential Max plan offers up to 400 Mbps download and 40 Mbps upload, with a Speed Score of 80/100, above San Francisco’s city average of 69, and is available to 100.0% of the city. Because satellite performance differs from lower-latency wired connections, check what other technologies are available at your specific address before choosing.

About Starlink
Starlink uses satellite internet, so it can provide broad reach and practical everyday service, including speeds up to 400 Mbps down and 40 Mbps up on its Residential Max plan, but satellite connections can have higher latency than wired options. Its Residential Max plan is available to 100% of San Francisco and has an excellent 80/100 Speed Score, while the 200 Mbps and 100 Mbps plans are slower, so it is worth checking your address for fiber or cable first if you need the best performance for gaming, video calls, or heavy streaming.

How We Analyze Internet in San Francisco
FCC Broadband Data
We use the FCC National Broadband Map, updated twice a year with provider-reported coverage at the census block level.
Speed Score
A state-wide percentile of each plan’s maximum advertised download speed against every option filed with the FCC in the state, all technologies on one scale. It is not a measured speed test.
Coverage Calculation
Provider coverage shows what percentage of census blocks in San Francisco report service availability from each provider.
Data Coverage for San Francisco
How We Calculate Speed Score
The Speed Score is a state-wide percentile from 0 to 100. It answers one question: of every internet option filed with the FCC in this state, across every technology, what share is slower than this plan’s maximum advertised download speed?
What goes in:
- The plan’s maximum advertised download speed, as the provider files it with the FCC and lists it for sale.
- Every other serviceable option in the state from the FCC Broadband Data Collection, counted by the census blocks it reaches.
Speed Score = share of the state’s filed options with a lower advertised download speed
A score of 85 means this plan’s advertised speed beats 85% of the options filed in the state. Fiber, cable, DSL, fixed wireless and satellite are all on the same scale, so a 1,000 Mbps plan scores the same whoever sells it.
What it is not: a measured speed test. It does not include latency, upload speed, reliability or congestion. Real throughput at an address varies with wiring, equipment and time of day.
How providers are ordered on this page: each provider’s tier scores are averaged across the census blocks it serves, then multiplied by the share of the city it reaches. Wired providers rank ahead of wireless-only ones, and satellite last, because their filings describe a signal footprint rather than a plant. The same rule sets the title and the 30-second verdict.

How We Calculate Capabilities
Estimated Capabilities predict how well each internet plan supports common household activities based on speed requirements and connection type.
Rating Scale:
- Excellent – Optimal performance, handles peak usage easily
- Good – Reliable performance with minimal issues
- Fair – Functional but may experience slowdowns during heavy use
- Poor – Not recommended; expect frequent buffering or lag
How We Rate Each Category:
Streaming
Based on download speed. 4K streaming requires 25+ Mbps per stream; HD requires 5+ Mbps. We account for multiple simultaneous streams.
Multi-device
Evaluates total bandwidth capacity divided by typical household device count (phones, tablets, smart TVs, computers). Fiber and cable handle many devices better than DSL or satellite.
Gaming
Considers both upload speed (for sending game data) and latency (ping time). Fiber and cable excel here; satellite connections struggle due to inherent signal delay.
Whole Home
Assesses whether the connection can reliably serve an entire household during peak evening hours. Factors in technology type (shared vs. dedicated bandwidth) and total speed capacity.
Note: Actual performance depends on your specific location, network congestion, and equipment quality.
