What is the best internet provider in San Diego?

As you’d expect from a big city, San Diego has plenty of choices when it comes to Internet Service Providers (ISPs). The big three in the city are AT&T, Spectrum, and Cox.

AT&T offers solid value and wide coverage, with speeds up to 1,000 Mbps. Spectrum service is fast and has no data caps, so there’s no limit to how much you can use it each month. And Cox offers the second-largest coverage area, bringing service to most of the downtown area and the northern suburbs.

HughesNet and Viasat are also available, if you prefer satellite, live in the outskirts of San Diego, or just aren’t happy with any of your other options. Both providers are available nationwide and are a great way to get internet service in areas that don’t have landline access.

Technology Type

DSL:

DSL provides internet service via phone cables and is up to ten times faster than dial-up service.

Cable:

Cable provides internet speeds faster than DSL through the same cables used for cable TV.

Satellite:

Satellite internet is widely available, but offers slower speeds due to a far-traveling signal.

Fiber:

Fiber relies on glass strands to relay digital code and is much faster than both DSL and cable.

Highest-rated internet providers in San Diego

EarthLink is the top-rated ISP available in San Diego, according to our 2020 customer satisfaction survey. The provider placed first overall and scored high in every individual category, especially customer service and price.

Spectrum and AT&T got average scores for installation, tech support, and reliability—making them a solid choice for a good online experience. Cox isn’t quite as stellar as AT&T and Spectrum, ranking among the bottom five in most categories in our 2020 survey.

Fastest internet service providers in San Diego

AT&T offers internet at speeds up to 1000 Mbps

EarthLink offers internet at speeds up to 1000 Mbps

Cox Communications offers internet at speeds up to 940 Mbps

Sail Internet offers internet at speeds up to 300 Mbps

AT&T offers the fastest internet service in San Diego, with fiber speeds up to 1,000 Mbps. Using that kind of speed, you could download an entire HD movie in less than 30 seconds. If you don’t need that much speed, there are plenty of other AT&T options for around $50 a month (or $40 when bundled).

Spectrum and Cox are both cable internet providers, and while their speeds can’t quite match the fiber speeds of AT&T, they both offer more than enough for the average user.

Spectrum speeds can reach 940 Mbps in some areas, while Cox can go as fast as 1,000 Mbps if Cox Gigablast is available (although it will cost you almost $100 per month). Both are plenty for gaming, streaming, or any other online activity.

San Diego residential internet coverage

San Diego’s a big place, but AT&T manages to cover the entire downtown area and suburbs, including La Jolla, Scripps Ranch, and Mission Bay. The only spots you likely won’t get AT&T coverage are the state parks and military bases.

Spectrum service is available mostly on the northwest side of town, north of the Mission Valley Freeway. This includes Silver Strand State Beach and Mira Mesa. Unfortunately, Spectrum doesn’t cover the downtown area, so you’ll have to look at AT&T or Cox if you live in that part of town.

Cox is available across most of San Diego but misses the coastal areas west of the Miramar Air Station. If you prefer cable to fiber, Cox makes a good alternative. Google Fiber is also available in select areas of San Diego, along with a handful of local providers including Telscape.

And if none of these providers meet your needs, HughesNet and Viasat offer satellite internet across the entire area (and nationwide). These satellite providers are a good option if they’re your only option, but you should go with a landline connection if it’s available to you.

Customer service is very good. We have never had problems getting repairs or techs to our house. We have TV, Internet and security; all with cox. Like I say, customer service is great and we use them A LOT!!!!! because their systems are crap. Our tv goes out all the time. Internet is intermittent and their security is terrible. I can not use the security app remote. I have to be home to set and unarm. They told me to close the app and restart again. Right! So I can now change all my passwords and security information. I think not. What a pain in the butt. I’m going to look for a different provider.

AT&T has the most incompetent customer service. It requires innumerable calls and they still can't get it right. Try not to business with AT&T if at all possible!

Cox has always been expensive but at least it was reliable. Now it’s outrageous and completely unreliable. So much so that all my neighbors in San Diego are constantly talking about how disconnected we feel. Dial up speed and constant drops in our signals. We’ve had Cox out to fix the issue and they throw their hands up and blame AT&T. I wish Google Fiber was available in our neighborhood.
