What is the best internet provider in San Diego?

AT&T - Great value
EarthLink - Multiple service types available
Cox Communications - High-quality equipment
Viasat - Widely available

The best internet provider in San Diego is AT&T—but only if you can get a fiber plan. Otherwise, stick with Spectrum or Cox for a fast and affordable cable connection.

AT&T’s fiber plans start at 300 Mbps speeds and go all the way up to 5,000 Mbps. So no matter what plan you get, you’re getting something fast and extremely reliable. Prices are reasonable, and you get unlimited data with no contract and plenty of opportunities for deals and promotions.

EarthLink has similar plans to AT&T because it uses AT&T’s fiber lines to get you service; EarthLink has top-rated customer service, so go for that if you value an internet provider with a sympathetic bedside manner.

AT&T also has DSL internet, but it’s not as fast or cost effective—only go for that if you live in a rural part of East or North County.

Spectrum is the second-best option in San Diego, with a variety of plans that give you speeds ranging from 250 Mbps to 1,000 Mbps. Since it’s a cable connection, you don’t get symmetrical upload speeds like you would with AT&T, but these plans are still fast and stay fast even during times of neighborhood-wide network congestion.

Prices for Spectrum plans are roughly the same as AT&T’s fiber plans, and you also get unlimited data and no contracts. Cox Communications is a solid third pick, with speeds similar to Spectrum but higher prices and contracts on its plans.

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.

What is the fastest internet provider in San Diego?

AT&T has the fastest internet service in San Diego—in fact, it has the fastest internet from a major provider in the whole country. The AT&T 5G Internet plan boasts 5,000 Mbps speeds, which is way faster than most people realistically need, but it’s still very impressive.

You can also get plans with 2,000 Mbps, 1,000 Mbps, and slower speeds from AT&T. All of the fiber plans also have symmetrical upload speeds, so the uploads are just as fast as the downloads. And these same speeds are available from EarthLink too, since EarthLink uses AT&T’s fiber network infrastructure.

Spectrum and Cox are the second-fastest internet providers in San Diego. The Spectrum Internet® Gig plan delivers download speeds up to 1,000 Mbps (wireless speeds may vary) using cable instead of fiber. Cox’s Gigablast plan lists a maximum speed of 1,000 Mbps. Both of these gigabit plans deliver upload speeds of 35 Mbps—up to 500 Mbps in some areas if you go with Spectrum.

Uploads are much slower than downloads on cable internet, but that should still be solid for most people.

What is the cheapest internet provider in San Diego?

EarthLink, Spectrum, and Cox are the cheapest internet providers in San Diego. All three offer basic plans for around $50 a month (or a little less). AT&T also has an excellent fiber plan for $55 a month that gives you much faster speeds.

There aren’t a lot of truly cheap internet options in San Diego, unfortunately—expect to pay at least $50 to $60 a month for reliable internet service in the city. That’s about average for internet prices nationwide. When you’re looking for cheap internet, aim to get a cable or fiber plan that gets you speeds of at least 100 Mbps.

Fiber delivers the fastest speeds and most reliable connection, and it’s often cheaper or equal to the price of lesser connection types.

San Diego residential internet coverage

AT&T covers San Diego’s entire downtown area and suburbs, including La Jolla and Scripps Ranch. The only spots you likely don’t get AT&T coverage are the state parks and military bases.

Spectrum is primarily available on the northwest side of town, north of Interstate 8. Unfortunately, Spectrum doesn’t cover the downtown area, so you’ll have to look at AT&T or Cox if you live in neighborhoods like North Park, South Park, or City Heights.

Cox Communications is available across most of San Diego but misses areas of North County like La Jolla, Torrey Pines, and University City. If you can’t get fiber, Cox’s cable internet makes a great alternative. Google Fiber is also available in select areas of San Diego, along with a handful of local providers, including Telscape.

If you live in rural parts of East and North County where you can’t get internet access easily, HughesNet and Viasat offer satellite internet across the entire region. These satellite providers are a good option if you have no other alternative, but they’re slower and cost more.

Methodology

HighSpeedInternet.com compares internet providers within cities and metro areas to give customers the most relevant insights into their internet options. When comparing providers, we consider the following:

Provider coverage areas
Advertised speeds
Real-world speeds (speed test data)
Customer feedback
Other relevant localized data

We source localized coverage data displayed on our coverage maps from the FCC coverage database, which is updated every six months. For the most current summary of providers in your area, we recommend you use our zip code search tool, which offers the most recent coverage data straight from internet service providers (ISPs).

Our city overviews compare advertised provider speeds. We may also include real-world speed data gathered from millions of annual speed test results. To process our speed test data, we first filter out outliers and providers with low test counts. We then calculate speed averages with every ISP subject to the same parameters.

We gather ISP customer feedback data from our comprehensive annual surveys and direct customer feedback submitted to HighSpeedInternet.com. Unless stated otherwise, average ratings are calculated nationally.
