How we review internet in San Diego
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 180 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.

San Diego internet customer reviews
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.
3/5

What speed do you need?
The internet speed you need depends on the number of devices connected to your network and the types of internet activities you and your household engage in.
If you live in a small household of one or two light internet users, 100 – 300 Mbps should be sufficient. If you live in a midsize or larger household of three or more people, each with multiple devices, then opt for a mid- or high-tiered internet plan of 300 – 1,000 Mbps.
Gig speeds and higher are best for very heavy internet users, large households with many connected devices or those who need the most speed for their activities, like downloading large amounts of data, gaming, working from home, etc.
