What is the best internet provider in San Diego?

• AT&T - Great value
• Spectrum - No data capsCTAM Plans

• Verizon Home Internet - Fast upload and download speeds
• Hughesnet - Perfect for rural areas
• 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.

SpectrumCTAM Plans 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.

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.

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.

SpectrumCTAM Plans 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.
