Best internet providers in San Diego, CA
Whether you’re streaming Max or teaching your grandma how to FaceTime, AT&T Fiber is one of the best internet providers in San Diego, California. The provider’s top-rated fiber service offers fast, symmetrical speeds that let you download a large movie file faster than it takes a Tesla to steal your parking spot in Mission Beach. Another great option is Spectrum, which offers a cable internet connection with speeds up to 1,000Mbps. In terms of speed and reliability, fiber providers should definitely be the first pick for any San Diegan, and cable providers second. However, college students and other folks on a budget can also try out T-Mobile 5G Home Internet, which is widely available, easy to install, and stays at a fixed price.
Keep reading below to learn about the best internet providers in America’s Finest City.
Who actually has the best internet in San Diego?
AT&T Fiber offers some of the best internet services in San Diego. The fiber provider offers speeds ranging from 300Mbps all the way up to 5Gbps over a symmetrical fiber-optic connection—though 5Gbps is way more bandwidth than most regular households need. AT&T is also top-rated in our books for its great overall quality, fast speeds, and impressive customer service. You can bet you can count on it to play League of Legends with low ping rates, take uninterrupted Zoom calls all day, or upload an Instagram reel of your hike at Cowles Mountain without spending hours waiting for it to finish posting.
What internet provider has the biggest coverage area in San Diego?
T-Mobile 5G Home Internet has the biggest coverage area among the most feasible internet providers you would want in San Diego. The 5G fixed wireless is available in over 76% of SD’s residential areas, according to the Federal Communications Commission. Even though T-Mobile has the greatest availability, a 5G wireless connection isn’t always the most reliable, so it’s best to go with a fiber or cable provider. Fiber/DSL provider AT&T and cable provider Cox also both have large footprints in the city—72% and 67%, respectively.
Satellite internet providers Starlink, Viasat, and HughesNet offer 100% availability among residential homes in San Diego, but their high-cost plans and limited speeds mean they’re not the best options for most internet users.
AT&T Internet: Best fiber internet
Only about a quarter of households in San Diego have access to AT&T’s fiber internet, but if you’re one of the lucky few, we highly recommend it. You have gigabit and even multi-gigabit speed options to choose from, and every plan comes with unlimited data and no equipment fees. Prices start at just $55 a month, and considering how high rent prices can be in San Diego, the idea of getting awesome internet speeds for a price that affordable sounds pretty nice. You can also bundle together an AT&T cell phone plan and DIRECTV with your fiber plan so you watch the San Diego Padres play at Petco Park without leaving your living room. Best AT&T internet plan for most people: AT&T Internet Fiber 1 GIG, up to 1,000Mbps download speeds for $80/mo.
Spectrum internet: Fast and widely available cable
Depending on what internet plan you choose, Spectrum offers speeds between 300Mbps and 1,000Mbps. Spectrum raises the price on your bill after the first year of service, but prices are generous and you don’t have to worry about data caps or an annual contract. Also, it’s worth sticking around for the bundle discounts you get with Spectrum’s cell phone and live TV service. If you’re a sports fan, Spectrum TV hooks you up with all the local channels to catch Padres games or SDSU basketball games. Best Spectrum internet plan for most people: Spectrum Internet Ultra, 500Mbps for $69.99/mo.
T-Mobile 5G Home Internet: Ideal for cable cutters
T-Mobile 5G Home Internet makes for a fantastic alternative for college students, budget-conscious households, and anyone else who’s weary of extra fees, annual contracts, and other internet provider shenanigans. Just like it sounds, T-Mobile 5G Home Internet taps into the carrier’s wireless cellular network to provide a fast 5G Wi-Fi connection—no fiber or cable lines required, making for a quick and easy setup. Prices start at $50 a month and data speeds max out at 245Mbps. Simplifying things further, you don’t need to stress about paying for equipment or installation, or shelling out for data overage charges or early termination fees. And new customers can get lots of promo offers. Best T-Mobile Home Internet plan for most people: T-Mobile 5G Home Internet Unlimited with 72Mbps–245Mbps for $50.00/mo.

Does San Diego Spectrum have Spectrum Gig Internet?
Yes, Spectrum offers its Internet Gig plan in San Diego. The Internet Gig plan costs $79.99 a month and delivers speeds up to 1,000Mbps. It’s great to get if you need tons of bandwidth to support a large number of Wi-Fi users in your household for streaming, gaming, and working from home.
What alternatives are there to Cox TV and internet in San Diego?
There are several alternative bundles to Cox TV and internet in San Diego, including AT&T Internet with DIRECTV or Spectrum internet with cable TV. AT&T co-owns DIRECTV, so it’s easy to add it to your internet plan, but you don’t get a discount when you combine the two. Spectrum is much less widely available in San Diego, but it offers a variety of cable TV bundles, as well as a free unlimited mobile phone plan for a year when you sign up for internet. Spectrum’s TV services also don’t have a contract, which may make it a more enticing option.
What is the best San Diego cable and internet deal?
One of the best San Diego cable and internet deals is AT&T Internet 300 bundled with the DIRECTV Entertainment Package. This deal is priced at $124.99 per month with a two-year agreement. The deal comes with home internet with 300Mbps download speed, more than 165 satellite channels, local channels, and the first three months of select streaming services for free.

Test your internet speed
Is your home internet fast enough to meet your daily Wi-Fi needs? The best way to find out is by running a speed test, which gives you a snapshot of how much bandwidth you’re getting from your internet provider. Run the test over a hardwired ethernet connection for the most accurate results, and try taking the test at different times throughout the day to measure possible fluctuations in your download speed, upload speed, and latency.
If you have trouble getting things done online with the speed-test results you’re getting, consider upgrading to a faster plan or switching internet providers.
