Fastest wireless network 2020: It’s not even close

Dallas: T-Mobile Has the Best Speeds

In the Big D, T-Mobile came up big, posting the best average download and upload speeds in LTE tests across the metroplex.

T-Mobile averaged a 47.4 Mbps download speed in our Dallas testing. The only carrier to come close to that was also using T-Mobile's network — Metro by T-Mobile, which posted a 45.3 Mbps. Those speeds were more than double Verizon's 20.5 Mbps result.

T-Mobile was also a big winner for upload speeds, too, with an 18.8 Mbps average. After Metro's 14.7 Mbps result, the next closest carrier was Verizon, which averaged 10.4 Mbps on uploads.

Sprint9.4 Mbps2.5 Mbps1:00
Cricket5.3 Mbps5.6 Mbps0:41

The only area where T-Mobile didn't finish on top in Dallas was in our app download test. Here, Verizon posted the best average time at 19 seconds. Both Straight Talk (32 seconds) and AT&T (33 seconds) finished just ahead of T-Mobile's 34 second time.

Cricket's cap on data speeds makes it hard for the carrier to compete. But even though Cricket posted a back-of-the-pack average download speed of 5.3 Mbps, it still managed to download Discord in an average time of 41 seconds. Sprint needed a full minute to download the app, and its 9.41 Mbps average download speed in Dallas won't excite anyone.

Our results reflect an average of five tests conducted at six sites around Dallas. At each test site, we also downloaded the 40MB Discord app from the Google Play store onto Galaxy S9 phones tied to each carrier.

T-Mobile may be the top network in Dallas, but Verizon takes the overall crown as the fastest wireless network in the U.S. Check out our full national results.

Looking Ahead to 5G: While our speed testing focuses entirely on LTE, the reality is that carriers are beginning to launch 5G service in some markets. In Dallas, Sprint has launched its 5G network, and we've had a chance to test out the carrier's 5G network with a 5G-ready LG V50 ThinQ. So far, we've found Sprint's effort to be more reliable than Verizon's initial 5G network, though it's not as fast.

    2016? Your tests are from September of 2015 and despite not being that "old", things have changed a lot since then and again, is not from 2016. Bad clickbait headline!

    i call BS. Verizon is only 5% faster than tmobile yet the same app downloads 40% faster on Verizon?

    You should change what speeds were actually being measured. Verizon does not have 24Megabytes per second download. That is insane cellular data speeds and is very very misleading. Those numbers are most likely Megabits* speed, not Megabytes. Mbps stands for Megabits. 1 Megabyte = 6 Megabits. When you download those speed test apps or go to websites testing your internet speed, you are testing the Megabits. So you should be seeing 144Mbps when you measure your speeds on the websites and apps. I am very certain you are not seeing such speeds via cell data lol. Not even close actually.

    @CHRISFO1 I easily get 50-100Mbps via Ookla on Straight Talk/AT&T. If you'd like a screen cap I can easily get you a few tested over the last half year or so.

    In San Jose, I can safely say that T-Mobile is easily 2-3x faster than Verizon in most places (we have both.) Some places Verizon is faster or as fast. However T-Mobile's coverage kind of stinks. It's either all or nothing and you get nothing far too frequently whereas Verizon can range from slow to fast, but it always works.
    So speed tests are interesting, but I'm really more interested in consistent good performance in the most places, not rockin' fast performance in spots. Based on my experience, that's how these two measure up.
    Despite that, I'm eyeing the day I can switch to T-Mobile. Sadly some places I currently need coverage (remote rural) T-Mobile simply has no signal whatsoever.

    Definitely depends on which part of the Country you are in. Maybe I'm just in a really great spot, but I get around 130 Mbps download and 15 upload (Sprint, Galaxy S7 Edge, Ookla speedtest app) and these results are fairly consistent

    Cricket advertises their speed at 8Mbps - it is not meant to be as fast as AT&T - its also A LOT less expensive.

    These tests are always meaningless. Verizon spends its money in cities. Sprint is hardly a national carrier, drive through flyover country with a sprint phone and you will be roaming on the verizon network most of the time.

    I'm in North jersey and since my galaxy S8 got here last week I've been averaging download speeds on sprint btwn 35mbps to 45mbps with two tests this weekend as high as 67mbps. I drive for a living and those speeds have been pretty consistent across much of the urban/suburban NY metro area. Those speeds are twice as fast as what I was getting with my S6 five days ago. Maybe the new in phone antenna is the difference. Sprint has been trying to get manufacturers to build phones with the latest antenna for a while now and Samsung finally delivered. I'm sure Verizon had something to do with delaying advancement in technology especially by a competitor.
