About home internet in San Diego
Updated on September 18, 2025
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 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.

What is the best home internet provider in San Diego?
The best home 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.
- Spectrum - No data caps
- Cox Communications - High-quality equipment
- AT&T - Great valueAQS Plans for AT&T
- EarthLink - Multiple service types available
- Verizon Home Internet - Fast upload and download speeds
- Hughesnet - Perfect for rural areas
AT&T’s fiber plans start at 300Mbps speeds and go all the way up to 5,000Mbps. 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 available to new customers.
Spectrum is the second-best option in San Diego, with a variety of plans that give you speeds ranging from 100Mbps to 1,000Mbps. 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 is a solid third pick, with speeds similar to Spectrum but higher prices and contracts on its plans.

What is the fastest home internet provider in San Diego?
AT&T has the fastest home internet service in San Diego—in fact, it has the fastest home internet from a major provider in the whole country. The AT&T 5G Internet plan boasts 5,000Mbps speeds, which is way faster than most people realistically need, but it’s still very impressive.
You can also get plans with 2,000Mbps, 1,000Mbps, 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 1,000Mbps (wireless speeds may vary) using cable instead of fiber. Cox’s Gigablast plan lists a maximum speed of 1,000Mbps. Both of these gigabit plans deliver upload speeds of 35 Mbps—up to 500Mbps 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 home internet provider in San Diego?
EarthLink, Spectrum, and Cox are the cheapest home 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 home 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 home 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.

FAQ about home internet in San Diego
What’s the best internet provider in San Diego?
AT&T’s fiber internet is the best internet service in the San Diego area due to its fast symmetrical speeds, fair rates, and wide fiber coverage. Plans start at $55 a month for 300Mbps.
If you don’t have access to AT&T’s fiber plans, Cox’s cable internet is a good alternative. Cable internet is fast, reliable, and has a broad coverage area via the same coaxial cables onced used for cable TV. The only downside is Cox’s service lacks the symmetrical speeds of AT&T’s fiber. Nonetheless, you can still get excellent download speeds at decent rates from Cox.
How much is internet in San Diego?
Internet in San Diego usually costs around $60 per month. You can get plans for cheaper or faster plans that cost more, but that's how much you should expect to pay for a fiber or cable internet plan that gives you generous speeds of 100 Mbps to 300 Mbps.
What cable companies are in San Diego?
Spectrum and Cox Communications are the two main cable internet companies in San Diego. Cox offers cable TV and internet bundles at a discount that can be cheaper than paying for these services separately. With Spectrum, you can mix-and-match any of its TV and internet services—each one comes with discounted pricing for 12 months.
What provider has the cheapest internet?
Cox is the cheapest internet service provider in San Diego. Its Go Fast plan starts at $50 per month and comes with 100Mbps speeds, which is adequate for one- to two-person households or homes with light bandwidth needs.
If you qualify for certain government assistance programs, you can apply for Cox’s low-income internet plans, Connect Assist and Connect2Compete, which cost just $30 and $9.95 per month respectively.
What is the fastest internet service?
AT&T is the fastest widely available ISP in San Diego with symmetrical speeds up to 5Gbps (5,000Mbps); that’s enough speed for 200 simultaneous 4K video streams. Though that's overkill for most homes, AT&T also offers a lot of speed for the money on all its plans compared to the region’s other ISPs.
While not technically the fastest, Cox is another superfast ISP in San Diego that offers even more Mbps per dollar than AT&T, with gigabit plans starting at $60 per month. Cox’s real-world average download speeds were the fastest in the nation, according to the 7 million speed tests analyzed in our Fastest ISPs Report. Also, this ISP is known for providing free speed upgrades for it’s customers.
The only downside is Cox’s cable internet isn’t capable of symmetrical speeds, so your upload speeds will be much slower than AT&T, though this isn’t a problem for most households: Almost everything we do online uses primarily download speed.
Which internet provider has the biggest coverage area?
T-Mobile Home Internet has the widest coverage area in San Diego. Fixed-wireless services like T-Mobile use cell towers to deliver internet signal to your home, allowing for enormous coverage areas.
Cox and AT&T’s coverage areas are a close second to T-Mobile, as both are widely available throughout the San Diego area.
How do I find the best Wi-Fi in my area?
San Diego’s SD Access 4 All program provides free Wi-Fi at over 300 libraries, parks, and recreation areas: Many locations even include an outdoor community computer lab. You can also check out a hotspot device from San Diego Libraries for up to 90 days at a time. All you need is a library card in good standing.
How do I know if my internet is good?
A good internet connection is one that you hardly notice because it works in the background to keep all your online activity running smoothly. If you regularly experience interruptions in your streaming, browsing, and downloading, chances are your internet plan isn’t adequate.
We recommend checking your internet speeds with our speed test. If you’re not sure how much internet speed your need, use our How Much Internet Speed Do I Need tool to estimate your household’s bandwidth needs. Lastly, use our zip code search tool to compare your plan speeds and prices to other plans in your area.
Customer reviews of internet providers in San Diego
Julie E | 05-16-2024
I work from home and was constantly dropping from Zoom meetings. I haven't dropped once since getting Google Fiber Webpass and have had amazing speed.

Over the course of about 10 years, and not counting the initial promotional rate, Spectrum raised their prices 7% year-over-year on average, which seems obscene when most companies cap annual pay increases at 5%, for extraordinarily exceptional work. When I was still on cable, the service was serviceable and adequate, which, if they were working off employee performance metrics, would merit 3% year-over-year. Absurdly greedy and out of touch. I switched to much worse service with T-Mobile Home Wireless Internet and sleep better for it.

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.
