I can see the voLTE in the menu but I can't turn it on. Has anyone had any success getting voLTE working on a n910u with Rogers?

I have the same device, but I don't see voLTE menu. Where did you find that menu? I have this question as well.

first off are you running 5.0.1?
settings > more networks > mobile networks > voLTE call (this is greyed out and I cant toggle it.)
There is also a toggle in the pull down bar from the top where I can also try to enable voLTE but it says "voLTE is not supported by your current software version. Contact customer service for more details."

Thanks for your reply!
Yes I am running Android 5.0.1.
I don't see voLTE setting anywhere. This is odd. Which region(CSC) ROM are you using? I am currently using Taiwanese (CSC-->BRI) ROM.

BRI is the region code(CSC) for Taiwan. Sorry about the confusion.
Some carriers only make voLTE services available for carrier branded devices, not unlocked/international devices. I will flash the Hong Kong ROM and find out either it's a carrier-related issue or a ROM(software) related issue.
Hmm wonder if there is a way to spoof my device type.
I flashed the Hong Kong ROM and I can confirm that voLTE feature is enabled by the carrier. I tested this out with T-Mobile USA and AT&T. I was able to make voLTE calls on AT&T, but not on T-Mobile. This is not a device problem.

I wouldn't call the carrier. When I called T-Mobile USA, their response was "Your phone is not supported on the network, therefore you won't be able to utilize any feature of the network properly."
Can I install that Hong kong ROM on sm-910c
Hi, this is my first post on XDA.
I ordered a LG V20 H990DS unlocked Taiwanese edition from Amazon for T-Mobile US. It is a good phone and it works really well with TMo LTE. However, two features are missing: VoLTE and Wi-Fi Calling. Does anyone know how to turn on VoLTE or add VoLTE for unlocked phones? Do I need to root it and flash it with a T-Mobile ROM? If so, will it lock me into TMo?
Thanks in advance!

Yes. I too bought this version that is lg v20 h990ds. I am nowhere able to see option to enable volte
Build version : NRD90M
Software version : V10b-twn-xx
Please let us know how to get this enabled ?

Are yousure you have the h990ds and not h990n? Because h990n has it
Try downloading the app "quick shortcut maker" and search for Wi-Fi calling. It is hidden in the US unlocked model. You should have bought the US unlocked model. Amazon, BH and Best Buy sell it.

Hi. See the other post for my response.
Hi Guys wanted to find out if VoLTE for T-Mobile was working on any CSC's ? I can sacrifice WiFi calling and RCS just want VoLTE . Wondering if it works on BTU CSC. Was reading and looks like Nougat Beta 1 CSC had alot of support for many VoLTE on many carriers. Also was reading that Samsung implemented various framework to allow VoLTE to work in Nougat without many modifications needed. Is this true and would upgrading to a Nougat ROM be enough to get VoLTE to work ?

If you want Tmobile Volte and Wifi Calling to work with your G935F, G930F or the dual
sim models here is a link to my custom rom with all the Tmobile features built-in to it:.
https://forum.xda-developers.com/s7-edge/development/rom-nougat-7-dplt-wifi-calling-volte-t3540723
Check it out!
The only requirements for tmobile wifi calling and volte to work properly is
that you use a Tmobile Sim card and you are on the Tmobile network.
Good luck, have a great day!

I have an unlocked T mobile s7 edge SM-G935T working on 7.0 Nougat...There's no voLTE feature in it..I want to enable it...Which firmware or CSC should I install..currently my CSC is TMB....please help
Are there any custom ROMs (and CSC files) that allow the S8 to successfully have WiFi Calling and VoLTE on the AT&T network??
I am running RENOVATE ICE 3.0 but you need the Notorious Kernel 1.9 for Volte to work on T. Some kernels do not support Volte, but Notorious does. You also need to flash ATT from the Flashable CSC Selection V1.0.0, and create/edit the /efs/imei/mps_code.dat and put ATT in there. You can also delete the /system/omc/ATT/res directory to get rid of the annoying T jingle and boot screen. You then need to call ATT and ask the friendly customer service person to update your IMEI. But when you give them your current IMEI, they will not be able to find it since it is not a ATT phone. So they will use the IMEI of a similar phone. That will get Volte to work. But WiFi will not as I think the IMEI must match exactly in their system for WiFi to work.
Hello. I'm also trying to figure out the same. How can I unlock the G955U? is that even possible?
Ideally I'd like to get the CSC Patch installed so I can get WiFi Calling on ATT, as I do not have any reception in my area. Any Help here would be appreciated.
Can anyone help here? Thanks.

You can flash csc seletcion after the rom.
That package contains the csc of att and the US generic. That generic is the one that I use and it works volte, wifi calling in tmobile ...
Hi Eddie, would you happen to know how to Root the G955U? its the Unlocked version of the phone. I've followed every step for CF-Auto-Root through Odin, but it fails every time. It seems like the Bootloader is locked? Any help would be appreciated here.

If you mean network unlock, then follow the ToS on AT&T mobile and eventually you will be allowed to unlock your phone. And for you to switch from the firmware of SM-G955U to SM-G955U1, you gotta go to this forum: https://forum.xda-developers.com/galaxy-s8/how-to/rd-carrier-switch-root-snapdragon-t3597473
You will not get wifi calling unless u can provide to att an imei from a device that has wifi calling. Only feature u will get working is volte. It's different them tmobile.

I am familiar with the need for an IMEI from a branded device ..... But I'm not even completely sure that's working for the S8+ like it did for my S7
I just haven't gotten anyone to 100% confirm WiFi calling on AT&T even with proper IMEI

Well i don't know from experience with at&t firmware but at&t should have wifi calling by default. If not and if wifi calling is an important feature towards you, then the last resort answer you have is to flash unlock firmware onto your device since that's the firmware everyone can use while it supports wifi calling and VoLTE (Voice Over LTE)

Once again, per other threads and myself, simply flashing the att firmware will only give you VOLte. You can toggle the wifi calling but it will say your account doesn't have this feature after about 5 seconds. If u call them and give them an imei number that is to a device that is an att device with the feature it will work. This is different then tmobile which will allow u both without doing anything except flashing their firmware.

Hello all ..... ( and @Tkkg1994 )
I'm still trying to get a definitive answer --- Has anyone personally been able to get an unbranded S8 or S8+ to activate WiFi Calling on the AT&T network (not TMo or others) ??
I'm trying to facilitate an issue with using S8 Ports on my unbranded S7 Edge where we can get VoLTE to work nicely but WiFi Calling will not activate (on the S8 port based ROMs).
I am aware (and have been for quite a while) that you must have an AT&T branded IMEI to get this to work on AT&T. I am also aware that this step is not needed on TMobile or really any other network.
I have tried the branded S7 IMEI that works great on my S7 to activate WiFi Calling while using many (most) S7 based ROMs. I have even tried branded IMEI's from ATT branded S8's and S8+'s .... but I can't get WiFi calling to activate while on any of the S8 port based ROMS (I get VoLTE nicely with many ROMS esp the latest BatMan S8 port ROM)
So to troubleshoot I am trying to confirm that even with the S8 or S8+ that WIFi Calling is or is not a possibilty ??
Thanks

I am no developer, but I believe there are two possible causes in the case of T WiFi failure on Exynos:
Perhaps T requires the IMEI to exactly match as a security measure, and since they cannot use an International model IMEI it will never work.
Or there is something specifically compiled for the Snapdragon process and so when it is extract it will not run on the Exynos.
Either way, it won't work. I posted a LOGCAT when enabling it failed, but it is beyond my capability to debug and no one seemed to be able to figure it out.

It depends on the model. If you have an unlocked US model, then WiFi Calling, VoLTE and Band 12 are already supported. My model of S8 is G950U1

I think it might be a mix + carrier needs to support and device needs to be whitelisted in their system. Which model do you have or planning to buy?
XAA will contain most US carrier's CSC codes, so this what US unlocked model comes with.
TMB is for T-Mobile, which is the same as sold by T-Mobile.

If you put T-Mobile sim card, then go to phone app and access the settings and then check if you see WiFi Calling there. To find out what you CSC is, just download Phone INFO app(Samsung) from play store. The launch the app and swipe to the left to go to CSC section.

USA(XAA) is an unlocked version that works with US carriers.

Right, I had that question myself before, but you have to make sure which model you have and what is the CSC of your phone. Carrier versions should be: G950U, but US unlocked is: G950U1. There is a little difference in XAA and others, but if you really want unlocked that would have CSC codes of most US carriers, then use XAA image. It will allow you to put any US sim card in the phone and it should work.
I would suggest checking out the carrier switching threads here. There are several... One here and at least one other I think in the T-Mobile S8 guides forums section, that walk you through changing the firmware to the US unlocked while keeping carrier features.

You will need to download the USA(XAA) firmware. That will give you the unbloated version and you will have WiFi calling and volte with T-Mobile. Just type in sm-g930u1 and select the XAA firmware. I have full T-Mobile capabilities with that firmware which is the US Unlocked model.
Make sure to use the regular csc file and NOT the home csc file.
