Best Internet Providers in San Diego, California

What is the best internet provider in San Diego?

San Diego presents a few options for home internet service, but AT&T Fiber is CNET’s pick for the best internet service provider for most San Diego households. AT&T Fiber isn’t available everywhere in America’s Finest City, so Cox, Spectrum or T-Mobile may be your go-to, depending on what’s available in your area.

The most affordable internet service in San Diego is Race Communications’ $25 per month plan, offering 25 megabits per second of speed. However, T-Mobile Home Internet and Verizon 5G Home Internet offer faster speeds and a better cost value. Plus, both ISPs offer discounts to eligible mobile customers, dropping your monthly bill to $35-$40. If you want the fastest plan, consider AT&T Fiber’s 5-gigabit tier (5,000Mbps) for $225 monthly.

Other available internet providers in San Diego

Google Fiber Webpass: Google doesn’t have a full-fledged fiber infrastructure in San Diego. Still, select locations throughout the area are hooked up to the provider’s Webpass service, which uses receivers mounted to rooftops and building exteriors to offer the residents inside high-speed fixed wireless connections. Availability is somewhat limited, but the terms are reasonable — gigabit speeds and no data caps for $63 per month with a year commitment or $70 per month without one.

Race Communications: Race is a hyper-targeted fiber-to-the-home provider servicing a scattering of small communities throughout California. That includes the 3,000 or so residents of Rancho Santa Fe to the north of San Diego. As a fiber provider, Race offers two service plans: $25 per month for speeds of 25Mbps and $70 monthly for 1,000Mbps speeds.

Satellite internet: Satellite internet from Hughesnet, Viasat or Starlink is an option wherever you live. But it shouldn’t be your first pick — with high prices and slow speeds, cheaper and faster options are available. 

Ting: A part of the internet services company Tucows, Ting Internet now offers fiber internet service in select markets in the US. Customers can sign up for gigabit speeds and no data caps at $89 per month, plus installation costs, an optional $11-$18 monthly equipment fee and an additional “monthly access fee.” Service appears to be centered south of the city, near Solana Beach. Ting’s fast speeds and appealing rates make it well worth a look if you live in that region.

Verizon 5G Home Internet: This cellular provider now offers home internet service at addresses with a strong enough 5G signal. With speeds of up to 1,000Mbps in some areas, Verizon can claim to be the fastest cellular internet provider in the US. The flat monthly rate of $50 with no data caps or price increases is tempting. Verizon promises not to raise your price for two years; you can make that three years by paying $70 per month. 

Cheap internet options in San Diego

Most providers in San Diego offer home internet service starting at around $50 per month. If you need a basic connection and want to pay as little as possible, that’s a good place to start. While Race Communications technically offers the cheapest internet service — $25 for 25Mbps — you’ll save more money per Mbps and get faster speeds by going through T-Mobile or Verizon instead. Both providers offer discounts to eligible mobile users, dropping your monthly bill to $35-$40.

Most providers we’ve mentioned also participate in the FCC’s Affordable Connectivity Program, which gives eligible low-income households a $30 monthly discount (or up to $75 for households on tribal lands) for high-speed internet. You can use the ACP toward any internet plan — not just the cheapest ones — from participating providers.

What’s a good internet speed?

Most internet connection plans can now handle basic productivity and communication tasks. If you’re looking for an internet plan that can accommodate videoconferencing, streaming video or gaming, you’ll have a better experience with a more robust connection. Here’s an overview of the recommended minimum download speeds for various applications, according to the FCC. Note that these are only guidelines — and that internet speed, service and performance vary by connection type, provider and address.

For more information, refer to our guide on how much internet speed you really need.

• 0 to 5Mbps allows you to tackle the basics — browsing the internet, sending and receiving email, streaming low-quality video.
• 5 to 40Mbps gives you higher-quality video streaming and videoconferencing.
• 40 to 100Mbps should give one user sufficient bandwidth to satisfy the demands of modern telecommuting, video streaming and online gaming. 
• 100 to 500Mbps allows one to two users to simultaneously engage in high-bandwidth activities like videoconferencing, streaming and online gaming. 
• 500 to 1,000Mbps allows three or more users to engage in high-bandwidth activities at the same time.

How CNET chose the best internet providers in San Diego

Internet service providers are numerous and regional. Unlike the latest smartphone, laptop, router or kitchen tool, it’s impractical to personally test every internet service provider in a given city. So what’s our approach? For starters, we tap into a proprietary database of pricing, availability and speed information that draws from our own historical ISP data, partner data and mapping information from the Federal Communications Commission at FCC.gov. 

But it doesn’t end there. We go to the FCC’s website to check our data and ensure we consider every ISP that provides service in an area. We also input local addresses on provider websites to find specific options for residents. We look at sources, including the American Customer Satisfaction Index and J.D. Power, to evaluate how happy customers are with an ISP’s service. ISP plans and prices are subject to frequent changes; all information provided is accurate as of publication. 

Once we have this localized information, we ask three main questions: 

• Does the provider offer access to reasonably fast internet speeds? 
• Do customers get decent value for what they’re paying? 
• Are customers happy with their service? 

While the answer to those questions is often layered and complex, the providers who come closest to “yes” on all three are the ones we recommend. When selecting the cheapest internet service, we look for the plans with the lowest monthly fee, though we also factor in things like price increases, equipment fees and contracts. Choosing the fastest internet service is relatively straightforward. We look at advertised upload and download speeds and consider real-world speed data from sources like Ookla and FCC reports.

What’s the final word on internet providers in San Diego?

AT&T Fiber’s most affordable plan gets you matching upload and download speeds of 300Mbps for $55 per month, which would be more than enough for most households. If you’re itching for gigabit speeds, you can go with the provider’s 1,000Mbps plan or one of its multi-gig plans of 2Gbps or 5Gbps. If fiber and cable aren’t available at your address, it’s worth checking to see if a cellular, fixed wireless connection from T-Mobile or Verizon might be available.
