Anyone using a SM-G930F on T-Mobile US?

Boy, if there's a way to get a rooted Exynos S7 to function on Tmobile with wifi calling, VoLTE, & all LTE bands functioning, the 820 locked bootloader won't matter to me at all. Sounds promising.
Once again, all TMo US LTE bands are supported by the F, FD and W8 variants. The 3G Band 4 is not, but that only affects areas that are not refarmed yet. So, only VoLTE and wifi calling are not supported.
EDIT: Thanks @chenxiaolong for the correction. B4 AWS 3G is supported.

http://www.samsung.com/uk/consumer/mobile-devices/smartphones/galaxy-s/SM-G935FZDABTU indicates that it supports the 3G AWS bands (band 4 - 1700MHz), unless that information is incorrect.
I stand corrected - thank you. Below is a screenshot from http://www.samsung.com/au/galaxy-s7/buy/#spec. For a list of T-Mobile frequencies, see this Wikipedia page.

Could you theoretically install this firmware on any International Galaxy S7 in order to obtain Wi-Fi calling and vo LTE on T-Mobile? I live in the USA, I'm not sure if this would be a region lock thing.

How do updates work for the F model? Is it one standard phone but different OS variations based on country? What Odin image do you use to update an F model to the latest Samsung OS for use on T-Mobile? Can you put any F phone country carrier image on an F phone? Also the cheapest I've been seeing the 930F on eBay buy it now is $688.99 by techno.trading.house. Did you use the same or different seller? Did you buy it now or did you bid on auction to get it so low?

Just as an FYI...
Long story short, I messed up trading in my old phones when I switched to T-Mobile, found out the service won't work for me with the amount of driving I do, and now can't get my old phones back. So I now own both the Galaxy S7 G930T I got from T-Mo as well as a G930F that I just purchased on Amazon (interestingly with an Afghanistan region code) to switch to AT&T for better band compatibility.
I've used both back to back, and the Exynos cellular radio on the G930F is not as effective on T-Mobile as the G930T's Snapdragon equivalent. In my office, I get -86-88 dBm with the G930T, and -96-97 dBm. I think that's a significant difference. Both are connected to the same tower on LTE band 4.
TL;DR: Somehow, the T-Mobile version of the phone gets noticeably better signal in the same location than the International G930F does.

Have you tried messing with ROMs and flashes to see if you can get VoLTE working on the F?
I know in the past you could flash a tmobile s3 tar with Odin onto a att s3 and make it tmobile firmware.
I've also read and told you can flash tmobile s7 stock tar on international model.
Not sure if Odin would fail or not .
I'm thinking about buying one and seeing what a gonna be made of the development and just sell my metro s7 while the price is still high and buyers are looking .
Either way I don't need volte it's a battery drain I always disable it .
WiFi calling is a must sorta I bet there is a work around. I'm willing to be that U.S s7 tar works on a international model
VoLTE is not a battery drain. That is a misconception. It has no impact until a call is actually made.
It was found that in the s5 in the begining when volte was pushed as an update disabling that fixed some drains
I haven't been able to find anything for the US in the F model Sammobile images. What do most Americans use on T-Mobile? UK and deal with the language variations (colour vs color)? Are there language differences in the firmwares? And if so, how do people make the phones more US English friendly?
Least expensive 930F seller is currently 232tech at $599.99 with an EU charger. Is that the one you guys were using?

You can choose English (US) when doing initial setup. No language variations.

Here is the official t-mobile marshmallow firmware for Germany. I will be testing with t-mobile usa when I go home on the 13th of April. If anyone can test this before me, please let me know how it goes

Are you talking about flashing different firmware on the 930f or the 930t
My thought is what if 930f users can flash tmobile 930t tar and get tmobile software on a international 930f.
I mentioned this in another post because I had a att s3 that I did flash tmobile s3 firmware onto and worked great
This might get us the ability to use WiFi calling and volte.
And still be rooted since 930f it's unlocked bootloader someone can make a rom that's built off 930t source
