I'm on T-Mobile, but I would rather buy the International version of the S7 to eliminate bloatware and to have the Exynos processor, not to mention the unlocked S7 is cheaper. However, I would like to use VolTE and Wi-Fi calling too. Will I have these features if I buy the international unlocked version?

I've never had any of my unlocked phones support WiFi calling or VoLTE, only T-Mobile branded phones did.
you will probably have to flash the t-mobile roms from your country (I guess states?!). If you get a exynos S7 and some t-mobile usa branded roms for that VoLTE and WiFiCalling shouldn't be a problem. Getting those roms for the SM-G930F might be your biggest problem.

How readily will the roms be available? I remember doing it for my HTC One M7 a few times and it wasn't too bad.
I also thought some phones like the Nexus 6P supported VoLTE and Wi-Fi Calling on T-Mobile?
The intl version does not have band 12, wifi calling on TMO, or VoLTE support on TMO.
Don't do it.
Thanks.

oh yeah, and finally, heres the actual samsung product page
http://www.samsung.com/uk/consumer/mobile-devices/smartphones/galaxy-s/SM-G935FZDABTU
so, there it is...the g935 has band 12...unless samsung is wrong?
Man, those sites provide confusing answers because there's one g935f owner on this forum who has T-Mobile who said it doesn't support VoLTE and Wi-Fi calling.

That's because t mobile used to add their specific code to their phones' firmware. But now they're built into android so they may work.

When you state now they're built in, do you mean in Marshmallow?
I remember reading that's how the Nexus 6p gained the ability to use band 12 LTE support.
http://www.tmonews.com/2015/12/some...nd-12-lte-support-after-android-6-0-1-update/
Unbranded versions of the firmware do not support VOLTE for some inexplicable reason (the feature is there, just hidden), while some carriers do, they even use the same firmware with only a CSC change (like unbranded the XEF French unbranded firmware vs French Bouygues BOG firmware)
There is no T-mobile USA firmware for the Exynos/international variant but there are plenty of European carrier that handle VOLTE and have no branding, just flash the respective firmwares or CSC using ODIN (does not trip knox) which will enable the feature (you may need to perform a factory init to apply the CSC change)
I'm using the latest XEF firmware in my s6 intl 920F. Where do you get the csc to flash to enable these features?

That's right. Not sure about volte, but the wifi calling was added to marshmallow: http://www.phone-probe.com/android-m-features-native-wifi-calling/

That's for nexus devices, Samsung only enables WiFi calling on carrier branded ROM's.
If you buy the unlocked international version, you will not get VOLTE or WiFi calling. You will get band 12.

Isn't this the first Samsung phone that comes with marshmallow?
Before marshmallow, wifi calling had to be added by the carrier to their rom like t-mobile did on moto and samsung phones.
I don't know for sure, just speculating
Can anyone actually confirm who had the Intl version that volte doesn't work

I don't have the s7, but I did have the international note 5. When i received the marshmallow ota, a volte icon appeared in the quick toggles bar. When i tried to click it to turn volte on an error message popped saying that carrier is not supported. I tried both with a T-Mobile and at&t sim.
The s7 may be different, but I highly doubt it.

So far, I've read that maybe the Czech T-Mo firmware works for VoLTE in the US. Can anyone confirm this? Or any of the other T-Mobile firmware options? I'm guessing wifi calling is a pipe dream....
I'm really looking for a T-Mo firmware that allows VoLTE on US T-Mo from a country with Samsung Pay active. Any leads?
Hi all,
I've read up on a couple of threads here relating to using an international version of the S7 on T-Mobile (Reason being because I want a white version of the phone). People say that the phone works fine other than VoLTE and Wifi Calling. Unfortunetly, Wifi calling is huge for me because T-Mobile service is spotty in my home town and at work and the only way I can get a solid signal is through Wifi.
I was wondering if it would be possible to somehow flash some T-Mobile software onto this international device that would make it think that it is a 930T device and get Wifi calling to work.

I just got an unlocked Samsung Galaxy J3 (2017) J327A from Amazon. This is an unlocked version of an AT&T prepaid phone. My T-Mobile SIM works OK with it. But: (1) VoLTE is not enabled, meaning T-Mobile will not work on 700 MHz Band 12 (which is the whole reason I got this phone, we don't have coverage here on any other band) and (2) wifi calling is greyed out and unavailable.
I had not realized there is more to switching between carriers than just "locked" or "unlocked", because there are different features beyond the basics that are either supported or not supported, and it turns out that having either VoLTE and/or Wifi Calling is pretty much essential for me now.
I'm an utter newbie regarding firmware mods. Is there any hope of changing the firmware on this model to enable VoLTE on T-Mobile and/or wifi calling on T-Mobile? A quick search of this forum only found complaints about seeing a "Wierd VoLTE icon" when they rooted their J327T phone. Which to me actually seems hopeful. The update guides I've seen all warn that firmware must be loaded only into the exact model number called out. Not sure if that means just "J327" or for example "J327x"
My question is: can you change an Unlocked J327A (supporting AT&T features) to a J327T (supporting T-Mobile features) by software tools? Or are there hardware differences, or at least serial-number-based locks to prevent that?
Would like to do the same thing, any luck?
I'm shopping for an s10e. I've done a lot of searching but haven't found anyone specifically saying this will work or not.
Does anyone use T-Mobile in the US and have the international unlocked version?
Does wifi calling work? VOLTE? Anything else you could add?
Thanks!
I think it will work if with VoLTE and Wi-Fi Calling you flash the service with the Unlocked (SM-G970U1) firmware. There is a thread that lasts it how to get access to our and flash it on different variants of the S10e. I'm at work so I can't hunt it down for you.
I have international S10e (SM-G970F) and use Ultramobile (MVNO on T-Mobile's network) and both VoLTE and WiFi calling work flawlessly.

That thread is for flashing across the US Snapdragon variants I believe.
