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 want to know the current root status for Galaxy S8/S8+ go to this forum: https://forum.xda-developers.com/galaxy-s8/how-to/current-root-progress-g950u-g955u-t3623444

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.

Thank you for the answer
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.
I'm looking for a rom/firmware that has all of the unlocked features from the U model but, with Verizon video and wifi calling working. If there is nonavailable would I be able to make my own rom? And if so how would I go about doing that?
HI
I have a dual Sim S8 g950FD, i bought it from Singapore airport.
I want to use the wifi calling option but it is not available under any of the conditions that i have used
I have attempted unsuccessfully to flash a stock rom which i assume would have got rid of any of the carrier restrictions that they have on the handset. it failed as the stock rom was older than the installed software.
All i want to do is use the Wifi calling function
Any ideas or links would be most helpful
thanks in avdvance
Anyone know a way to get hotspot working without popping the sim card out?
I read some people mentioning flashing unlocked firmware will let you hotspot without provisioning.
Phone is currently on G950USQU5CRK1
Updato.com has firmware for Code USC
Will this work for me? Is there any hope or am I regulated to doing the sim card dance on every hotspot?
I'm on the unlocked firmware and have no restriction. The hotspot is unlocked and no carrier block is on it. I use the hotspot all the time and it was a main reason I went with the unlocked firmware.
Hi,
Aim:
The aim is to get VoLTE working so that the phone can work in India on the Reliance Jio network. "Work" as in makes and receives calls through the native phone and messaging apps.
A bit of context:
I have a Samsung S7 Edge SM-G935F.
I am want to use the phone on a network that is 4G only meaning I need VoLTE enabled for the calls and texts.
Currently I am running the XEU firmware, but VoLTE is not working when I use the Reliance Jio sim.
PDA: G935FXXU8ETI2
CSC: G935FXEU8ETI3
If you need more context info let me know.
Questions:
So, basically, I am trying to figure out the easiest, non-intrusive way to enable VoLTE without having to unlock bootloader, root the device, etc...etc. (don't even know if it is possible this way). Anway...
The first question is, can I flash a VoLTE firmware from region/network A and use the phone in any other region/network B? Will VoLTE work? Or is the VoLTE firmware specifically programmed to work networks in a particular region or a single network in a region? For example, can I flash EVR (EE UK) firmware (I think it has VoLTE feature enabled), and use the phone in India on the Reliance Jio network.
( If the suggestion in the first question is not possible )
The second question is, can I flash a SM-G935FD INS (Indian) firmware on the SM-G935F to get VoLTE working? Is it safe to flash an FD firmware to the F variant?
Thank you,
Ray
Hello, you can run Volte and Vowifi having root, you only need to know the operator's data settings for these functions
"Currently I am running the XEU firmware, but VoLTE is not working when I use the Reliance Jio sim." Does it work with another sim? Thats the impression I am getting. If it works with another sim and not your current one then it may be as simple as the phone provider not supporting the device for VoLTE. If it is a problem for all providers then you will need to change to a firmware with a CSC that supports VoLTE.
I'm facing the same Jio VoLTE problem on Moto G7 XT1962-1
