OpenSignal: Verizon vs AT&T vs T-Mobile vs Sprint LTE speed and reliability Q2 report

Gather around, carrier fandom, we've got the latest Q2 metrics on speed, availability, latency and 3G fallback for the big four US networks, courtesy of the OpenSignal's communal methodology. There are some notable changes since the info that came out before unlimited plans took over, namely that T-Mobile took all the glory for itself, while Verizon and AT&T are still making most of the money there is to make in the industry.

The second quarter saw the unlimited data plan offerings of the big two carriers take a toll on their network speed and availability, leaving T-Mobile ahead in all categories, albeit by a tad in some. Bear in mind that OpenSignal's data is crowdsourced, and users are mainly hailing from well-serviced areas, where T-Mobile has good coverage for the most part. The carrier beat Verizon in network availability as the testers reported a 4G signal on T-Mobile 90.9% of the time, compared to 89.8% for Verizon users. That's not a big difference, but the average speed of Verizon'd network also fell 2 Mbps to 14.9 Mbps after it introduced unlimited data plan, which is explicable, given how many more people are on Verizon compared to T-Mobile.

Verizon and AT&T still take the cake when it comes to coverage, especially in more rural areas, but when it comes to speed and latency, T-Mobile seems to deal with its workload better. Things get even dicier when we get down to the 32 individual markets that OpenSignal issued separate reports for. There, it is now a battle only between Verizon and T-Mobile, with either one of those being on top, or both virtually tied for dominance. It seems that you can't go wrong with either, if speed and availability are the things you look for in a carrier network.

I travel to the Caribbean often, Jamaica mostly, and T-mobile Wi-Fi Calling is prestine. Plus free international SMS/MMS without Wi-Fi. I was also in Canada recently and to my surprise Service was free there. I'm pleased with that. Plus since the recent upgrades at the end of summer, I get the better signal with T-Mobile deep inside my campus than Verizon, which has been the champion for all former years. Last year I considered switching, glad I stuck it out.

WRONG, t-crapo has NO SERVICE in all of SW Wisconsin, from Lacrosse all the way down to Dubuque IA. VZW, the best service, has red all over that area! Nice try t-crapo!

One location doesn't make it crap. I had crap service from Verizon in southern Wisconsin and had to use US cellular to get service for 5 years. This study isn't based on coverage, it's based on consumer experience. You should probably be more excited than angry since by the end of 2017 T-mo will have coverage in SW Wissonsin, plus it may be the 600mhz which could be far better than anything else available in your area. Don't switch if it doesn't work, but don't complain about a company that's improving the industry as a whole. (unless you work for VZW, then you can complain)

Haven't had T-Mobile since 2004 so I honestly can't remember what their customer service was like. I've had Verizon since then and their customer service is always been top-notch.

I found the exact opposite. I have had to call customer service a couple of times and both times T-mobile was amazing.

It's more like TMobile all The way in places you have service and don't travel. If you travel TMobile sucks. Before all of you fan boys open your trap doors see Root Metrics coverage reports. Smoke and mirrors. .

Exactly. T-Mo's good in major cities, but that's about it.

Here, t-mobile "LTE" speeds only hit 1.5 mbps, whereas Verizon hits 80mbps. I call BS on this all day

You are wrong half part, you can travel much far with tmobile, sure there still many dead zones. Any way compered just for 2 years ago is like 50-75% extra coverage. I was even have approach situation where verizon and att has no service but tmobile and sprint had one, slow and weak just to make call or send txt msg. You just need make choice what you want to pay for what service, my service with t-mobile is good enough for me and my family, if I have business that could be other story. One think you can't refuse they grow come not only from good price but better network service and access.

"I was even have approach situation where verizon and att has no service but tmobile and sprint had one..." That's all based on who's monopolizing the towers in the area.

If you travel to Canada and Mexico T-mobile rocks, free unlimited 4G that's faster than many US cities. Even if you travel to the rest of the world.

T-Mobile is much better for traveling internationally, but I wouldn't bet on RootMetrics being fair, they are paid by Verizon after all and they focus on a really small number of key areas...which coincidentally are places Verizon has always been strong in. OpenSignal does it much more responsibly and as accurately as you would experience since they are using you to test. They also do it at a much much bigger scale so they will naturally get a better picture instead of doing some statistical modeling to simulate coverage in areas they don't test. I think good evidence that Verizon is losing more customers than it ever has recently AND they JUST announced this: "Verizon Introduces New Unlimited Plans, Will Throttle Their Video and Your Old Plan’s Too" That isn't something you do if your network is able to handle the traffic because it drives old customers away. There are some catches. If you have an old phone, you may not see any benefit because that phone probably doesn't have the antenna to pick up the signal, but if you wait until new phones with the 600 mhz bands are rolled out next year or so, then you will get the best since T-Mobile bought enough 600 mhz spectrum to cover 100% of the US...while Verizon and AT&T could not even come close.
