Fastest internet plans in San Diego
The fastest internet in San Diego is AT&T Fiber’s 5,000 Mbps plan, which is widely available throughout the city (83% coverage). Google Fiber also offers fast, multi-gigabit 1,000 and 2,000 Mbps fiber plans, but only to a small portion of San Diego (3%).
While AT&T Fiber is your best option due to its fast speeds and widespread coverage, it’s not available everywhere. If AT&T or another fiber option isn’t available at your home, then cable internet providers like Spectrum and Cox provide strong alternatives. Spectrum provides speeds up to 1,000 Mbps, while Cox offers speeds up to 2,000 Mbps.
While cable and fiber are the fastest internet options, T-Mobile and Verizon also offer 5G internet plans with speeds up to 415 Mbps and 1,000 Mbps, respectively. Always check your address for accurate provider availability when shopping for a San Diego internet plan, and keep in mind that you may not necessarily need the fastest internet plan.

How we review internet in San Diego
We don’t just recommend the cheapest internet in San Diego. We use a rigorous multi-factor review system to ensure our San Diego internet reviews reflect the specific needs and preferences of our readers.
Our methodology
We evaluate broadband providers in four categories: affordability, performance, value and customer satisfaction. Each category contains multiple sub-factors, all of which are weighted differently to impact the provider’s overall score.
For each sub-factor, we score all providers on a continuous scale of one to five, relative to the industry as a whole. Because the average download speed in America is currently 290 Mbps, for example, we assigned all plans with download speeds between 100 and 299 Mbps a score between three and four. Xfinity’s 200 Mbps plan received a 3.50 score for download speed, while Spectrum’s 500 Mbps plan got a 3.71.
We only considered standardized data points in our scoring system. More abstract data like consistency of service and brand reputation is still part of our analysis, but we opted to let our writers address them in the context of each review.

On top of that, Google Fiber offers 24/7 support, which is why it earned our pick for the best customer service.
San Diego internet customer reviews
We aren’t your average internet marketplace: We believe transparency is key to earning your trust. That’s why we share real user reviews for the internet providers we cover, so you can learn what others are saying before you decide.
I have AT&T and really enjoy being able to make phone calls and play computer games with my family and friends.
5/5
Would be nice if they would stop pushing so hard to upsell their mobile service and instead offer a military discount or to waive the setup fee.
4/5
Cox has underwhelmed me with every interaction I’ve had. A website that won’t let you order service without a chat session first is annoying. Not clearly showing pricing is always an indicator that I might be being overcharged. I wouldn’t use them if there was a competitor with fiber speeds. Once that happens, I’m gone.
