Best internet providers in San Diego, CA

Spectrum Internet: Fast and widely available cable

Spectrum Internet pros and cons

pro
Pros
pro Affordable low-tier plans
pro No data caps on any plans
pro No contracts required
con
Cons
con Price hikes after one year
con $5 monthly Wi-Fi fee

Cable provider Spectrum offers up some of the fastest data speeds in the country. Depending on what internet plan you choose, your data speeds fall between 300Mbps and 1,000Mbps. Spectrum raises the price on your bill after the first year of service, but since you're not required to enter into a contract, you can always switch to a different internet provider before the price hike.

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’s 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.

We recommend the 500Mbps plan for most folks, but if you’re living in an apartment downtown with one or two people, you could make the 300Mbps plan work just fine.

AT&T Internet: Best fiber internet

AT&T Internet pros and cons

pro
Pros
pro Affordable fiber plans
pro No data caps for fiber plans
pro Included equipment costs
con
Cons
con Data caps with non-fiber plans
con Not much fiber availability

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 get blazing-fast symmetrical speeds from 1,000 to 5,000Mbps, and every plan has no data caps or equipment fees. The whole chimichanga is surprisingly inexpensive (it starts at $80 a month). Considering how high rent prices can be in San Diego, the idea of getting awesome internet speeds for an affordable price sounds pretty nice.

You can also bundle together an AT&T cell phone plan and DIRECTV with your fiber plan and save $20 on everything combined. It’s sure better than nothing!

Best AT&T internet plan for most people: AT&T Internet 1000, 1,000Mbps for $80/mo.

Gigabit speeds might be overkill if you live in a small apartment in San Diego, but if you’ve got a bigger household, gigabit speeds make for a much better experience.

T-Mobile 5G Home Internet: Ideal for cable cutters

T-Mobile Internet pros and cons

pro
Pros
pro Straightforward pricing
pro Easy installation
pro Low cost, no contract, and no extra fees
con
Cons
con Good but not great speeds
con Variable speed and reliability

T-Mobile 5G Home Internet makes for a fantastic alternative for anyone who’s grown weary of extra fees, annual contracts, and other internet provider shenanigans. Just like it sounds, T-Mobile 5G Home Internet taps into a wireless network to provide a fast 5G Wi-Fi connection—no fiber or cable lines required. Data speeds max out at 245Mbps, which works great for small-to-medium-size households.

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: $50 home internet, 72–245Mbps for $50.00/mo.

T-Mobile’s sole 5G internet plan costs a flat $50 a month—but you can get up to $20 a month off if you bundle it with a qualifying T-Mobile cellular plan. You probably won’t be blown away by 5G internet speeds, but it’s still enough for plenty of streaming and gaming.
