I'd much rather find out if the G930F will work before ordering it than go through the hassle of sending it back. Just doesn't make sense that a company would sell phones that don't work, but stranger things have happened. Thus my original post. I have no interest in rooting or alternate ROMs. Right now seems like I need to wait for the TMO version.
[T-Mobile Samsung Galaxy S7 Questions & Answers] lost_:
With the 930T you will get T-Mobile VoLTE, WiFi calling, and Band 4 3G in areas that have not been refarmed (is there still any left?), and T-Mobile support (and update, if they ever come out, LOL). I included support in one the pluses despite not ever relying on the provider for device support as I always root and custom ROM all phones.

If you don't care for any of the above, then the 930F would work and you could get it cheaper (even more so if you happen to have eBay Bucks), though if you factor the promotional offers, the 930T may end up cheaper.
[T-Mobile Samsung Galaxy S7 Questions & Answers] barondebxl:
I have ordered the G930F from eBay as well and that seller has sold a ton of them. I can't imagine that he wouldn't know about the region lock thing. Otherwise that would be so many returns lol
[T-Mobile Samsung Galaxy S7 Questions & Answers] rosenmat:
Just 930T cannot be rooted due to the locked bootloader... :( In this aspect 930F should be better. If it works with TMO.

Has anyone gotten one of these yet and can comment on VoLTE? I'm more concerned with that than Wi-Fi calling.
[T-Mobile Samsung Galaxy S7 Questions & Answers] duvalbmarley:
Only phones that have VoLTE are tmobile branded phones
[T-Mobile Samsung Galaxy S7 Questions & Answers] hella356:
I'm extremely interested in this possibility. Not keen on losing VoLTE & especially WiFi Calling, but if that's what it takes to get a rooted S7, I would happily settle for this.
[T-Mobile Samsung Galaxy S7 Questions & Answers] Python_69:
Hi! I got my Samsung Galaxy s7 930f today, so I was testing. Everything working fine, hsdpa, lte, I do not use VoLTE or Wifi calling, so I can't tell anything about it.

The price was $599 on the ebay. I use it in Clearwater, Fl, so looks like here the hsdpa working 1900mhz not 1700.

I have only one problem, the signal is little bit weaker than my another phone " Sony Xperia Z3 Compact ".
[T-Mobile Samsung Galaxy S7 Questions & Answers] km8j:
Are you on T-Mobile? Can you test VoLTE? Is there a setting for it?
[T-Mobile Samsung Galaxy S7 Questions & Answers] chenxiaolong:
I started looking into the framework for the G935F and G935T and from what I see, there are a lot of changes that Samsung made to get VoLTE to work with T-Mobile's servers. They did not go with the AOSP implementations of VoLTE and Wifi Calling that Google introduced in Marshmallow. They're still using the same custom implementation that they used on the Note 4. It's not easy, but I think it's possible to make VoLTE work with a custom ROM. If T-Mobile/Samsung won't unlock the bootloader of the G935T by the end of my return period, I'll probably buy the G935F and take a stab at making VoLTE work.

[MENTION=1637784]Python_69[/MENTION]: Was your device SIM and region unlocked when you got it? Did it work with a T-Mobile SIM right out of the box? Also, if you wouldn't mind, could you test if your phone can receive a band 12 LTE signal (for data only of course, since we don't have VoLTE yet)? Thanks!
[T-Mobile Samsung Galaxy S7 Questions & Answers] hella356:
If it becomes possible to run a rooted Exynos S7 on Tmobile & enact wifi calling & volte, it could basically become a work around for the locked bootloader of the 820 for those looking for TW based ROMs. I'm one, & from what I've read, the exynos sounds better for my needs anyway.
[T-Mobile Samsung Galaxy S7 Questions & Answers] Python_69:
Yes I'm on t mobile. I checked the setting but I did not see any settings about VoLTE.
[T-Mobile Samsung Galaxy S7 Questions & Answers] km8j:
Go into the phone app and then settings...
[T-Mobile Samsung Galaxy S7 Questions & Answers] hella356:
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.
[T-Mobile Samsung Galaxy S7 Questions & Answers] lost_:
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 [MENTION=4277844]chenxiaolong[/MENTION] for the correction. B4 AWS 3G is supported.
[T-Mobile Samsung Galaxy S7 Questions & Answers] chenxiaolong:
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.
[T-Mobile Samsung Galaxy S7 Questions & Answers] hella356:
That's an interesting possibility.
[T-Mobile Samsung Galaxy S7 Questions & Answers] km8j:
Who is going to try
[T-Mobile Samsung Galaxy S7 Questions & Answers] vprasad1:
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?
[T-Mobile Samsung Galaxy S7 Questions & Answers] km8j:
Someone needs to test this! I doubt going to work
[T-Mobile Samsung Galaxy S7 Questions & Answers] sweendiggler:
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.
[T-Mobile Samsung Galaxy S7 Questions & Answers] km8j:
Have you tried messing with ROMs and flashes to see if you can get VoLTE working on the F?
[T-Mobile Samsung Galaxy S7 Questions & Answers] androidddaaron:
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
[T-Mobile Samsung Galaxy S7 Questions & Answers] km8j:
VoLTE is not a battery drain. That is a misconception. It has no impact until a call is actually made.
[T-Mobile Samsung Galaxy S7 Questions & Answers] androidddaaron:
It was found that in the s5 in the begining when volte was pushed as an update disabling that fixed some drains
[T-Mobile Samsung Galaxy S7 Questions & Answers] vprasad1:
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?
[T-Mobile Samsung Galaxy S7 Questions & Answers] dew.man:
You can choose English (US) when doing initial setup. No language variations.

[T-Mobile Samsung Galaxy S7 Questions & Answers] androidddaaron:
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
[T-Mobile Samsung Galaxy S7 Questions & Answers] jjohn7293:
This is G930F firmware, for the G930F international phone. All European t-mobile versions are international phones.
[T-Mobile Samsung Galaxy S7 Questions & Answers] hella356:
The 930T version has SD820, the 930F has Exynos, so there's no way to make the US T-mobile firmware work on an international S7. There are also some people who have said they are going to try flashing the 930T firmware on an unlocked, SD820-based Chinese/Korean/etc. version. If this works, it should pretty much provide exactly what we would get if T-Mo unlocked the 930T, although it might prove a pain to get a hold of one of these Asian variants. Other potential bonus of this route is the possibility of getting a 64GB model.

I think what jjohn7293 is going to try to is to flash firmware from one of the European T-Mobile models (which are Exynos) onto an international Exynos S7. If all goes well, this will get VoLTE and WiFi Calling to work on the 930F on the T-Mobile US network. End result, if successful, is a rooted S7 with all the T-Mo features intact. Downsides are reputedly lesser call/data performance compared to the 820-based 930T, and any custom ROMs would be limited to stock-based TouchWiz versions. No AOSP/CM type ROMs (which doesn't matter to me, but will to a lot of people).

In either case, the odds don't look all that great, but there's a decent chance, and either (or both) could get us a satisfactory compromise to what we have now. Only time will tell.

Im looking into getting a G930F as well, but am hoping someone figures out how to get wifi calling to work first. I also had thought of flashing the stock 930T firmware, but hadnt thought of the different processors. The other thread linked about my port here looks like they are getting close. If they do I might just buy one.
[T-Mobile Samsung Galaxy S7 Questions & Answers] johnusesandroid:
so for the guys that already have the G930F for US T-Mobile, what country firmware did you guys use? I've read in a couple threads that the UK one is the most popular. But would there be any pros/cons for using the German T-Mobile (or any other country T-Mobile) firmware instead?

Tempted to buy this since it's cheaper than the T-Mobile version but I know I'll miss VoLTE. Those using this on T-Mobile, are the tradeoffs (no VoLTE, no Wifi calling, weaker radio maybe?) worth the benefits (No carrier bloat, exynos processor)?

Why didn't you have VoLTE or WiFi calling on T-Mobile? It's one of those things that is hard to go back from once you have it (VoLTE).

I could not get G930F onto my G930T, maybe T Mo is not up to date with the fact there is 32gb Qualcomm G930T and exynox with 32 and 64gb, we are stuck with the junk as usually.

Could get su onto G930T using Kingo su apk, set in developer options OEM unlock ....

PC8 firmware is garbage.
[T-Mobile Samsung Galaxy S7 Questions & Answers] samanbabah:
does anyone know if Samsung Pay on the G930F works in the US?
[T-Mobile Samsung Galaxy S7 Questions & Answers] MadRocker:
I travel too much, I shame most airline pilots traveling on international routes.

So any unlocked mobile phone like a few LG's and Samsung I bought in Netherlands, Panama, Germany, South Africa, Dubai worked with my Tmobile sim without issues.

Exception is Movistar Mexico that is on their own marijuana induced planet and nothing from Europe works well with 4G / LTE and a Mex Movistar sim card. Only stock Movistar devices. Wasted enough money on the movistar experiment.

No wifi calling but someone can dump the apk and link it to you.

F versions is likely Exynox chip and will not work on T hardware.

Closest to SM-G930T is the USA sprint version in terms of hardware or this is what I have read, so this is likely the closest flash onto T hardware that should work for now until someone used the Samsung source code and compiled a generic kernel for both Exynox and Qaulcomm versions.

I doubt this recompiled kernel and modules would arrive soon.

for me at least, i stay connected to band 12 while i am on a call. i use t-mobile with an international variant.
[T-Mobile Samsung Galaxy S7 Questions & Answers] Gam3r 4 Life:
Im using a white SM-G930FD and its been great so far. I thought I was going to miss not having VOLTE or Wifi calling (HD voice), but I found out that my S7's sounds better without it. I hadnt noticed until I got the international one that there is a hissing sound in the background of every word I hear on calls on my T-Mobile S7 while on an HD call. So I turned off volte and wifi calling and it went away. So this is one thing I thought I was going to miss from my T-Mobile S7 but I dont at all.

The other thing I thought I would miss was Samsung pay. But my bank (Capitol One 360) ended up saying they have no plans of going with Samsung pay and now have their own mobile pay app. I also can just use Android pay. So in the pros and cons list between the T-Mobile S7 and the international one they are now much closer. Not to mention how much faster the Exynos seems to be. So I will probably just end up selling the T-Mobile S7 once it is fully paid for. Still waiting on the BOGO card.

[T-Mobile Samsung Galaxy S7 Questions & Answers] rootuser11:
maybe because band 4 works fine in your area? mine picks up band 12 but most of the time it is on band 4
[T-Mobile Samsung Galaxy S7 Questions & Answers] darkdhanil:
I have the Tmobile one and the international one and i notice that on places where the TMO has LTE 4bars the international has LTE 2bars. Also with the TMO one i make a call and the signal stays in 4GLTE but with the international one it goes down to 3G and after i hang up goes back to LTE. Happens every time i make a call.

So i don't care about Wifi call or volte but i am worried about the signal strength. I got it because revew on the web say this one has 8 cores and battery last more. Plus is cheaper cost me $200 less than my TMO one that i'll be returning.

So 8 cores, better battery, no bloat, $200 less but weaker signal...............What you guys think?

Band 12 is meant for a VOLTE function. Noone has gotten an Non-tmobile Samsung S6 or S7 to work with t-mobile's VOLTE. There was one who tried a 930FD who had what turned out to be a false positive before returning the phone (was trying to use both ATT and TMO sims in one phone).

One developer ported S6's video call to the S5 (I PMed that dev but haven't heard back).

From what I can tell, doing so would involve modifying CSC files, modifying the ims version or adding settings for t-mobile and, somewhere in telephone stack and/or radio logs, ensuring the handoffs are setup correctly. I have tried on my own to do so (adding lines/settings from t-mobile CSC to international CSC) but with no success so far. Admittedly, it's above my coding experience. I'd be happy to start a bounty for 930F T-mobile US VOLTE + video call support at $50.
[T-Mobile Samsung Galaxy S7 Questions & Answers] Spud37:
So the only real difference that I have read on this thread are that is no wifi calling or VoLTE. Is VolTE actually worth having? I kinda want the international version for not only root but also because it runs cooler and faster.

I finally bought a G930F and plan to use it on T-Mobile USA.

Any personal experiences rooting and flashing custom ROMs?

I am upgrading from a Galaxy S5 G900T running CM13 which I like but can be a little unstable at times. I'm assuming most CM/AOSP based ROMs will have missing features found on the TW based ROMs. I really liked some of what the KryxOS ROM was doing with the app tray, google dialer and messenger app, but it looks like that is no longer being developed for the S7.

I just want something stable, fully functional and excellent battery life.

Any other important recommendations are appreciated!

For those of you using sm-g930f on Tmo (or other GSM network in US), do you get the 4G LTE icon or just 4G? I am using this model with a MetroPCS SIM (uses Tmo's network) and am getting LTE speeds (10-75Mbps down, 5-37Mbps up, depending on location) but the icon just says 4G.

Using the LTE Discovery app I can watch my phone switch from LTE Band 4 to LTE Band 12 when I go indoors for about a minute. All of the above speedtest results are were measured outside on LTE Band 4, but inside on Band 12 speedtests produce results in the *kbps*, well under 1 Mbps. I suppose this is no surprise - and presumably just confirms that the sm-g930f radio does support LTE Band 12, but my indoor reception of 700MHz is quite poor (as others have reported).
