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?

So it seems that most users are flashing G930U firmwares on their G930T (or G930A or G930V...) devices so that they can debloat, improve battery, etc. But I'm looking to do the reverse to pick up T-Mobile features. I would like to do so for a couple reasons:
1) I would like VoLTE to work and advanced messaging
2) I would like 4x4 MIMO and Carrier aggregation for T-Mobile bands
3) I would like T-Mobile WiFi calling
4) I would like to get faster (monthly-ish) updates from T-Mobile vs the slow updates from Samsung
Anyone have experience with this and get it to work? It seems like it should be possible with the snapdragon, I just can't find any threads about going this direction.

Wait, so just to clarify you don't have VoLTE or wifi calling on the 930U firmware?

WiFi calling is enabled in settings but never connects. WiFi calling is provisioned on the sim/phone line as I can get it to work with my Nexus 6p with that sim, but not the S7. And the VoLTE may be working but how do I check that?
When you're making a call does the icon go from LTE to H+ or does it stay on LTE? If it stays on LTE then you're making a VoLTE call, otherwise it's not.
Guide for jumping firmwares. You'd only be interested in the part about "returning to stock" for flashing the 930T firmware.

I know this an old thread but I just wanted to let everyone know that the ANDROID 8.0.0 G930U firmware (G930UUEU4CRG2) was just released over at Sammobile!
Physically I have the G930V phone... but I've been running the 930U firmware for over a year with no issues. I'd be curious how much I'm really missing (minus the bloat).
WiFi calling and txting seem to work fine.
Updates from tmo vs samsung seem to be about the same +/- a few weeks.
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?
Does anyone know how the Note 10+ Unlocked model in the US handles Volte for the various carriers? Usually you have to have a carrier specific CSC with that carrier's Volte present on the phone or Volte does not work.
Do the US Note 10+ Unlocked models come with all the US carrier CSC present and Volte?

Pretty much comes with multiple CSC of US carriers. I am on T-Mobile and WiFi Calling and VoLTE work
I'm on Straight Talk (using a Verizon SIM) and the Voltaren fine. Note 10
Volte on Verizon works fine. Although I don't see an HD when on a call, the voice calls sound extremely clear which may mean that HD calling is working. You can do data and voice at the same time also. The only thing missing on Verizon is video calling
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.
Hi,
Is wi-fi calling supported on XQ-AS62, US Variant of this phone ? If so, which networks. I am specifically interested if the feature works on Tmobile or a Tmobile MVNO.
I see contradictory information on the forums and hope someone who owns the phone can give a definitive answer.

As mentioned on other thread:
"Nope, I am using T-Mobile and Wi-Fi calling is not supported(no option in settings), even *#*#4636#*#* menu shows Wifi Calling Provisioned toggle disabled and Off (VoLTE Provisioned is disabled and On)"
I did some research and there is no definitive answer to why Wifi Calling doesn't work with T-Mobile but I suspect it has something to do with Certification from T-Mobile, Sony and T-Mobile should work like they did for VoLTE to enable Wifi Calling. (Not sure if rooting and adding some config will change this but out of Box Wifi Calling is not working with T-Mobile)
Thanks for the information. I assumed the North American variant meant it would support all network features of US carriers.
I see Sony Experia phones in the past that did support wi-fi calling on Tmobile, so its surprising they have dropped the support on their flagship phones.
