Quick question.
Have a Exynos Unlocked S8 Plus from awhile back. In the past there were modified CSC 's we could flash that ported T-Mobile features such as VoLTE and WiFi calling onto the device even though its an international device. Is that still possible on Android 9.0 or Pie if I update the device ? It is rooted and has TWRP installed.
Since T-Mobile is deactivating a lot of their 2G and 3G networks. VoLTE is increasingly important. Let me know. Thanks!

(Sorry, I should've posted this in the Q&A forum)
I have a G930A and from what I've read, I can either go with G930U or G930T.
A clean phone with the U is definitely tempting but I need WiFi calling (bad cell signal at work). The T is safer but I'll be living with Tmo bloat, and I also understand this is (for now) a 1-way upgrade because of bootloader versions.
If anyone here has the G930U on Tmo, can you confirm whether WiFi calling works or not?
Thanks!
Just as FYI, I am on the SM-G930FD (dual SIM international) , rooted and unlocked, with custom ROM and a CSC tweak (both are fron the XDA forum) , on T-Mobile USA with working (actually tested and made calls) Wi-Fi Calling.

So if you think of buying S7, you can seriously consider the 930F/D or 935F/D models.
I recently switched from AT&T to T-Mobile for their North America coverage plus 140 countries my US number works, and on the 2nd SIM I keep a local SIM (prepaid) of the country I am at for LTE data. Works like a charm.

Does B12 VoLTE work on the 930F?

B12 is supported by the phone, and T-Mobile US uses it for VoLTE and Wi-Fi calling.

Got an SM-G930U the other day and I can confirm that WiFi calling and VoLTE work right out of the box as soon you put in a T-Mobile SIM card.
Darn! I should've waited. I went with 930T just to be safe.
I guess I'll wait for 930U to come with bootloaded v3 and try again.
Thanks for confirming!

So wait ? I am confused ? have SM-G930FD (dual SIM international) , rooted and unlocked , but with stock ROM. Can I flash this CSC and I will be able to to have wifi calling with my T-mobile service ? Help ??. Oh wow ! CSC flashing did work and YES like a charm. :good::good:
I'm about to pull the trigger on buying the S7 and (thanks to this forum) have researched the (T-mobile) "carrier" version with SnapDragon processor vs. the International non-carrier version with Exynos processor. Seems like the latter is generally preferred, with 2 drawbacks:
1) Not compatible with T-Mobile's wifi calling;
2) No VOLTE
My only remaining questions are:
1) It seems as though with most unlocked / non-carrier smartphone models, custom ROMs are usually made available that enable carrier-specific features, but it seems like no such ROMs have yet been developed and widely circulated to enable T-Mobile's wifi calling or VOLTE. Is it typically just a matter of WHEN, rather than IF, such ROMs usually get into circulation? IOW, even though I'll be without those features on the Exynos S7 for now, can I buy the phone with confidence that in the not too distant future there SHOULD be a ROM to enable these? (Wifi calling is actually rather important to me since my gf's apt is a dead zone.)
2) Can someone ELI5 VOLTE to me? I'm still note entirely sure what it is / does, and want to evaluate how much I should care if my Exynos S7 doesn't support this...
Exynos does support volte. I am using it and it works fine.

Would you mind explaining how you got it working? Did you have to do anything other than change your CSC? I changed my CSC to T-Mobile US and I now have the option to enable wifi calling, however when I turn it on it just hangs there saying 'Enabling'.

Did you change it with that CSC changer v1.7?
That is really all I did. Install n7 rom then change CSC to TMB.

Yep that's what I used. I did a clean install of the SuperMan rom and used CSC changer again...same issue, it hangs at Enabling. Even went back to stock rom and it does the same thing.
Finally, I installed the Note 7 OnTheEdge rom like you said and it appears to be working, I now see the wifi calling notification at the top left and I get the volte icon when i'm not connected to wifi. I wonder if anyone has been able to get it to work on other roms?

I've only tried it on n7rom mentioned above. Guess it has to do with the rom since not working in Superman rom.

It works now. I do super man rom. Search that thread how to do it. You have to flash zto csc then boot then flash TMB csc. Then Switch a couple toggles.
Hello guys,
my phone is Samsung galaxy s6 G920F from UK and voLTE was not working here in India. (needed voLTE for calling on Reliance Jio network). i tried all possible thing available but it didn't worked for me. i tried changing CSC to INU/INS etc but none of that worked. Then i found this forum and by doing that it worked like a charm
https://forum.xda-developers.com/galaxy-s6/general/volte-fix-g920f-jio-users-root-t3550917
now my real question is that what i did to make voLTE work in 6.0.1 (using above forum), same i did for 7.0 but unfortunately it didn't worked.
So is there any way to get voLTE on 7.0 in S6 G920F because i have seen many different phone model owner on xda complaining that voLTE has stopped after they have updated to 7.0 nougat.

The reason why it worked previously is that you had CSC files for marshmallow, they probably don't work on nougat firmware. Your only option is to wait till nougat firmware is officially released which supports volte for jio.

Folks,
I have Galaxy A8 UAE version in the USA with MNVO SIM-card which is working on T-Mobile network. Of course VoLTE and VoWiFi features are unavailable on my A8 because it has wrong CSC (which is XSG). As I understand I need to change CSC code to add the features to my phone. But... as Galaxy A8 is not released in the USA there are no A8 ROM with CSC appliacble for the US. I'm wondering if there are any other ways to change CSC to one which will work with T-Mobile VoLTE (my previous Nokia 6 US-version had both features working fine with the same MNVO SIM). Could someone help me with that?
Follow the directions it works
Unfortunately this has stopped working.

If you rooted your device, you can install a TMB CSC from another Samsung phone if you know how.

I have gotten this to work but it sunlight stops working inverse new sound.
I will try to get a fix for this
Ok found fix
You must rooted .

Hello folks, there's any custom Roms that unlock 5g on unsuported countries or this only can be possible with magisk modules?
crDroid will unlock 4g, not sure about 5g as I need to get into town for that to work. It works. I think most custom roms do it.
StagOS did not, just a heads up.
Any update on this post
crDroid all functions work in China, cannot tell you about other places. Though with the may stock update 4g started working here for some reason, but I don't think VoLTE was working or wifi calling.
