Not all plans are available in all areas. Provider plan, availability, and speed tier data provided by BroadbandNow.com. Speedtest real-world data is only present where sample size has reached significance within a region. Additionally, averages may include aggregated tests across multiple Internet Types (Fiber, DSL, Cable, etc.).
San Jose is a city locals tease but fiercely defend. The weather is hard to beat, the food is diverse, and weekend plans can vary from visiting the redwoods or the coast. It may feel quieter than a big nightlife city, but San Jose is considered by residents a comfortable place to work, raise a family, and eat well.
And although traffic may often slow to a crawl, innovation cannot cease in the heart of Silicon Valley, so neither can internet speeds. Reliable, high-speed service is the backbone of daily life here. From home offices and cloud developers to students and streamers, residents count on consistent, fast connections to stay productive, creative, and connected.
So who provides the fastest speeds? According to Speedtest results from July through December 2025, AT&T Fiber leads in San Jose with median download speeds of 373.55 Mbps, followed by Xfinity at 328.19 Mbps. Across the city, the typical household sees fixed speeds around 272.24 Mbps down, which is enough for multitasking, remote work, and heavy streaming on multiple devices.
The right speed for your household depends on how you use the internet. For most households of three to four people watching a moderate amount of streaming video and performing simpler work-from-home tasks such as emailing, Slack, Zoom, etc., a 300 to 500 Mbps plan is more than enough. But for creators, tech professionals, or large households, gigabit speeds and strong upload performance make a noticeable difference.
How to Pick the Right Internet Provider in San Jose
Here are some practical tips:
Check Your Address
Many ISPs tout citywide coverage, but the reality is more complicated (like if your building isn’t wired for fiber). Use provider lookup tools or Speedtest’s zip code breakdowns to verify.
Consider More Than Speed
Reliability, customer support, and data caps matter just as much. Many fiber plans, for example, include unlimited data and no equipment rental fees. Watch out for plans that include data caps and extra charges.
Think About Uploads
If you send large files, stream on Twitch, or make frequent video calls, symmetrical upload/download speeds (only offered by fiber) are a game-changer.
Match a Plan to Your Needs
Don’t pay for 1 gigabit if you’re just browsing or streaming a few hours a night. On the flip side, don’t skimp if you’re running a business from home.
Read the Fine Print
Promo rates often expire after 12 months. Check for hidden fees, contracts, or equipment rentals that inflate the total cost.
How Much Speed Do I Need?
Download speeds of at least 100 Mbps and upload speeds of at least 10 Mbps are widely considered fast enough to handle nearly any online activity. A quick guide to what speeds you need for different online activities is below, and you can read our full guide to internet speeds and performance for more information.
