T-Mobile leases towers from Verizon and AT&T. Following the collapse of the AT&T and T-Mobile merger, T-Mobile divested it's network real estate (antenna)s to CrownCastle, and AT&T sold their towers to CrownCastle also. Verizon sold their towers to American Tower.
In most situations (like 95% of the time) AT&T and Verizon provide connectivity and Fiber to the towers they own. So when T-Mobile pays a lease to a tower, it still relies on Verizon or AT&T landline service to connect the equipment to the network.

Well, T-Mobile is at it again. Remember, they are a "Re-Carrier now, and if you've seen the past, ads, they look familiar. First, they are using the same "Re-Carrier" advertising strategy.
Here's how it works-- they'll advertise a new service and how it's better than a competitors, even when they haven't tested it; and remain ranked #4 (out of 4 companies) in coverage and service according to RootMetrics.
So here, you might get lucky and get 450MB speeds for a short time, but like clockwork, they'll start telling customers they need to upgrade. Two things happen.
Part 1- 1.) T-Mobile will also change the plan and how it's billed. (Look at Rate plans with "Unlimited" data; but then T-Mobile raised rates and Re-Advertised the terms of their service; changed how T-Mobile bills for video; and not Net-Neutrality Compliant with a plan called "Binge On".)
Part 2- Other people will upgrade and begin to use the service in your area. You won't get the advertised speed once one other person in your area upgrades. As an early adopter, take a picture of the speeds you had during that first week. This way, you can fondly look back at that speed test as you continue your 2-year contract term. Also you could post "SpeedTest" results online so T-Mobile they can get even more customers on the network.
Logically though... The engineering needs to get done. In order to get coverage and speed to the tower via landline fiber. In most parts of the US where T-Mobile leases space on Verizon's antenna structure, Verizon (or AT&T Landlines) has to bring fiber optic lines to the tower. So AT&T and Verizon will likely have the faster speed first. T-Mobile likes to advertise placing the cart before the horse, I guess.
Another problem T-Mobile has is the spectrum position and amount of airwaves. Verizon also has 800% more cellular airwaves, which travel "up to 4-times farther" than what T-Mobile advertises as LTE Extended Range service (Band 12). Having access to a larger amount of airwaves is important if you want coverage over wider distances and for more people (capacity). T-Mobile wants to increse their ad budget instead of providing service.
Either way, it's shady marketing T-Mobile uses. But it must be legal in the country Neville Ray is from. I believe he's still on a Green Card and not a US citizen and may not know about US's strict truth-in-advertising laws. That's probably why it's on a blog post. This is exactly what a "Re-Carrier" does.
It's cute how you posted that same scripted junk on Engadget. Oh and also a new user I see... interesting.
Anyway, we all know that RootMetrics study was junk. Here's the real-world deal - I used to have AT&T, and switched to T-Mobile personally about a year ago, and I have Verizon for work. So I feel pretty qualified to make a comparison. And TMO unequivocally blows the other two away for me. I have signal more often than family members with ATT, and the spots where TMO beats VZW and vice-versa are about even.
When it comes to speed, TMO always crushes the other two for me. No question. And the real world data from the likes of Ookla and OpenSignal backs that up.
Finally, when it comes to service, ATT was always ok. Not great, but not terrible. Verizon is absolutely awful! I have to deal with them constantly for sticking crap charges on our bill and all kinds of things like that. And half the time they make it worse rather than fixing it. No wonder they got in trouble for overcharging the DOD...
T-Mobile, once again, has always been fantastic with customer support.
All that to say, I wouldn't necessarily be mad if I had to use ATT for some reason. I never had any actual problems with them. T-Mobile is definitely my personal preference right now, both in terms of my plan (though I'm not the biggest fan of the new ONE thing), and in terms of service. And I would NEVER voluntarily switch to Verizon unless they really change their tune.
All that said, I know it's all different in different regions and what not. That's just my personal experience based on the last year or so. But I have been kind of all over the country in that period, and even enjoyed the free Canadian and European roaming (another bonus that blows Verizon in particular out of the water).
Funny how Sprint never even seems to be in these conversations
