5G Speeds in 2026: Which Carrier Is the Fastest?

It’s 2026, and more than 90% of the U.S. population lives in areas with good 5G coverage. That means more reliable connections and faster data speeds. But the three major mobile networks are not the same.

Third-party data shows that T-Mobile has the largest and fastest 5G network in the country, beating out AT&T and Verizon. My personal experience backs this up. When I perform a mobile speed test from my office in a relatively rural part of New England, I’m pulling 521 Mbps download speeds. That’s faster than the cable internet I have at home!

I’ll go over everything you need to know about rankings, but here’s a brief overview of where the three networks stand.

• T-Mobile: Still dominating the scoreboard with 95% 5G availability and ~309 Mbps median download speed.
• Verizon: Boasts the best reliability and video performance, and unparalleled speeds in areas with 5G Ultra Wideband coverage.
• AT&T: Decent all-around performance for both 5G speeds (~172 Mbps) and availability. Last year, AT&T spent $23 billion to acquire more low-mid band spectrum, suggesting that speeds will only go up.

For its latest Speedtest Award, Ookla tested the three major U.S. mobile networks. Drawing from millions of individual speed tests, Ookla evaluated various metrics, including “loaded latency” (which means testing your data speeds while the network is busy), to determine median download and upload speeds.

T-Mobile is the fastest 5G network in 2026, with the top download and upload speeds (309.41 Mbps and 13.57 Mbps, respectively).

Median download speeds: T-Mobile (309.41 Mbps), Verizon (214.17 Mbps), AT&T (172.79 Mbps)

Median upload speeds: T-Mobile (13.57 Mbps), Verizon (13.06 Mbps), AT&T (8.98 Mbps)

OpenSignal also tracks the performance of mobile networks in the United States. In its most recent Mobile Experience Awards, T-Mobile cleaned up, winning 12 of 16 categories.

T-Mobile won in the following categories: Video Experience, Live Video Experience, Games Experience, Download Speed Experience, Upload Speed Experience, 5G Games Experience, 5G Download Speed, 5G Upload Speed, 5G Coverage Experience, 5G Availability, Consistent Quality, and Reliability Experience.

Verizon won in the following categories: 5G Video Experience, 5G Live Video Experience, and Coverage Experience.

AT&T won the Time on Network category.

For many years, the term “5G” was thrown around haphazardly. Companies would use it to describe mobile networks that were just built on top of older, slower 4G networks (this was called the 4G crutch). However, these days, the real standard for 5G is called 5G standalone (or 5G SA).

Essentially, 5G standalone networks are better because they operate on newer infrastructure that was built for the task.

Some of the 5G standalone performance benefits include:

• Significantly lower latency: This is essential for online gaming and certain augmented reality features.
• Better device battery life: Devices don’t need to connect to both 5G and 4G networks at the same time with 5G SA, saving battery life.
• Improved upload speeds
• Better built-in security features

Both T-Mobile and Verizon have made particularly strong progress in expanding 5G SA coverage. As you can see from this test I did on T-Mobile’s 5G network, the download speed is an insane 521 Mbps with a latency of just 21 ms. At those speeds, it’s an ideal home internet solution.

There are several reasons why your 5G speeds might seem sluggish in 2026.

• Network: If you're on a non-standalone 5G network, speeds may fall short of the results above. You may see higher speeds in a different area or if your provider upgrades its network.
• Congestion: Even in areas with good 5G coverage, carriers can throttle speeds during high-traffic periods. That’s why Ookla’s loaded latency speed data above is helpful.
• Indoor penetration: While cell phone signals can usually travel through walls just fine, wide-band 5G signals (which use shorter, higher-frequency waves) can struggle. This is especially true for certain types of material, like metal, thick concrete, and brick.
• Device limitations: Not all 5G phones are created equal. Some older devices have chips that can’t handle the latest frequency bands in 2026. Maybe it’s time for an upgrade.
