T-Mo on Twitter confirms WiFi Calling Available for 6P but no Band 12 support - Nexus 6P General

https://twitter.com/TMobile/status/648919023158206464
This is a real disappointment. Granted it will eventually be added (hardware is already there, just isn't certified on T-Mo yet) but Band 12 support is the the biggest reason I want this phone. T-Mo inside of building is basically non-existent to the point I've considered changing carriers. My 6p doesn't arrive for a few weeks but I may cancel the pre-order before then because of this news.

That's not surprising, T-Mobile took forever last year to get wifi calling and it kind like B12 is their new toy to delay

I have tmobile..but what is band 12 support mean?

---

I wouldn't worry too much about this. It's a certification thing. The 6P is certainly capable. That means it's easily fixed via software update, which I'm sure will eventually happen. T-Mo seems to be reserving band 12 right now for the devices they directly sell, although they're able to list numerous reasons why that's just a coincidence. Eventually, the politics will pass, and this issue will quietly be resolved in the background.

Band 12 means you get support for 700 MHz. It's nothing necessarily new but T-Mobile h as been pushing out 700 MHz spectrum. The significance is that 700 MHz penetrates through buildings/walls better so you'll have better service/reception assuming your phone is in 700 MHz / Band 12.

Seems like T-Mobile is working with Google on this, I agree though.. it's more or less just certification and I'm sure it'll be approved as Google uses T-Mobile for Fi so they have a good relationship. Hopefully it'll be resolved before the launch.

Thanks. So I'll get even better reception once approved?

Hmm.. they did something like this with the Nexus 4. It came with Band 4 capability but it was disabled. Hopefully we can find a workaround again in the event T-Mobile doesn't cooperate.

---

thanks for the information, now I finally get why people have been complaining about Band 12.
I'm not getting it now with my Moto X Pure(I hope), nor have I with other phones so it'll be cool once I get it.

Another updated article.

Google is working on getting band 12 by ship date: https://nr.reddit.com/r/IAmA/commen...hi_lockheimer_here_at_google_with_the/cvjiteb

yup just saw that

I have yet to see and 12 on my Note 4. LA is supposed to have it, but many times when I'm in a building, I either get no reception or E, which is basically no reception. When I'm out and about, all I see is band 4, so as long as the 6P gets good band 4 reception, I'm good for the moment

---

I was wondering about WiFi calling since it's not sold direct through TMobile but looks like I won't have to worry

---

FYI to everyone, T-Mobile has a VERY legitimate reason for doing this. Since T-Mobile is working a transition to VoLTE, the new areas they expand Band12 to don't have traditional phone service. This means if your phone doesn't have VoLTE, you can have a signal but can't call 911 and there is no way to prioritize it to roaming to remedy that.
Consequently, its a safety issue. Since VoLTE is still early, there aren't enough standards and manufactures have to get certified through T-Mobile for it. As stated in the AMA, this shouldn't be an issue because google should get the nexus phones certified before the ship.

While we're on the topic of band 12, why does the 6P not have band 4 to band 12 carrier aggregation. The 5X has it, what the hell?

Nexus 6P:
CA DL: B2-B2, B2-B4, B2-B5, B2-B12, B2-B13, B2-B17, B2-B29, B4-B4, B4-B5, B4-B13, B4-B17, B4-B29, B41-B41
Nexus 5X:

As a t-mobile customer with band 4 and 12 coverage, and no band 2 coverage I really hope it's a misprint. T-Mobile holds the D, E, and F chunks of band 4 in north america so at least B4-B4 will probably provide a nice pile of bandwidth. It looks like Canadians on Bell/Rogers are going to get screwed by the lack of B4-B7 as well.

In layman's terms, what actually is meant by band 4 to 12 aggregation?

phone uses more than one band or tower at the same time.

after hours with nexus and Fi support the specs are correct. 5x has superior network hardware. 6p t-mobile users (in band 12 areas) are screwed.

Thanks for that. Afraid I'm in the dark on this. I tried searching for Tmobile band integration and couldn't find anything. Can you suggest a different search term or perhaps a link that explains the technology?
