So I have an S6 Edge running on EE but bought from the carphone warehouse. As such, I have recently found out that I cannot use WiFi calling as that is only available on handsets that have come directly from EE.
My first question is why is this? Is it something to do with IEMI numbers of trusted devices to make sure that only known phones can access that part of the network? Or is it that they put a different software build on the phone?
The 2nd question is that if it is a software difference, do we think it will ever be possible to enable this ourselves?
I'm quiet annoyed that I was told that I could use WiFi calling by the Carphone Warehouse when I bought the phone. Apparently it is only iPhones that are on EE that can use it if they haven't come directly from EE
You will be able to flash EE software via odin when released or in the short term you could get a refund from carphone as you have been miss sold if they guaranteed you wifi calling
Assuming that it is software that enables it then yep, I guess flashing is an option unless anyone can find where the difference is in the phone application (assuming that's where it is). Maybe its just a switch somewhere....
Damn, that's annoying. I was looking forward to having that feature, my parents house is in the back of beyond so I never get signal when I visit them.
If anyone has an EE supplied device, maybe you can check your build number to see if it matches my Carphone Warehouse one and maybe identify if there's just a build difference or something on EE's side that enables WiFi calling.
My build no: LRX22G.G925FXXU1AOCV

Got my phone from EE and the build number is:
LRX22G.G925FXXU1AOCY
Is the WiFi calling option completely missing or does it just not work?
The toggle in the phone application isn't there. Not sure how big the change set is between the 2 builds, I don't know much about decompiling android stuff either or where the configuration settings would be stored. Maybe someone here can shed some light on it...
I have exactly the same issue. My phone was bought from the Samsung Store in London (Carphone Warehouse in disguise) and I have no wifi calling option either.
Have any of you guys who want WiFi Calling rooted yet?
I ask because there are some files in the CSC folder that mentions WiFi Calling being enabled and such, so it may be either missing or set to False on other models and may just need changing.
I think flashing this EE firmware should enable this feature. I'm in same boat, EE from car phone warehouse. I can test if you want but it. Won't be for a few days as our Internet is out. I'm not really intrested in this feature as i get good coverage but it would be cool to try It.

I would imagine that would work.
For those of you who do get the option don't forget to text "Wifi calling" to 150 to get it activated on EEs side
Currently downloading both the EE firmware and my original firmware (just in case) and will see what happens on my S6 Edge. I see Kies is no longer supported so I guess I should use Smart Switch to do this rather than Odin?
Need my phone this morning for some development work so will try and flash that firmware this afternoon with Odin and will report back.

I flashed it, but no extra options appeared, but checking EE's website , they say you just make the call with no signal and it will connect via wifi instead , not sure how reliable this information is....
anybody else have any luck?

I would expect you to see the toggle for it in the phone application as per these setup instructions. Did you register by texting "wifi calling" to 150 also?

Those are much better instructions. Lol. But my menu only goes as far a vibrate. But I only dirty flashed. I'll give it another go tomorrow as I've got family coming round in a bit.
Did you flash the EE baseband too? Maybe it has something to do with the modem?
Download a Root Explorer and have a look in the CSC folder in System and post what the files in there contain?

Yeah.
but there is no CSC in my system folder. Any other ideas youd like trying.
Sorry I couldn't help you guys out more. buthe like i said if you have anything else you like me to test I don't mind. Anything for this community

In the phone type *#1234# and see what the CSC code is.
There are apps in the Play Store that let you change the CSC for the device, but I don't know whether they work for the s6 or not.
It's probably something to do with CSC though. You could try copying the CSC files from an EE firmware into the System Folder, but I have no idea if this will work or not.
CSC.zip (This is the CSC folder from my System Folder on EE s6 Edge)
Root.Zip (These 2 files were in the system folder, not in the CSC folder)

Bravo. That did it. Now have wifi calling enabled. Not that I'll use it but. It might come in handy one day.
and i have no way of testing it actually functions but the option is there in phone setting now
This just needs to be made in to a flashable zip to make it a little bit easier For some peole.
P.s just realised I'm not even on EE firmware any more reflashed this morning to stock u.k. so this should work for anyone.
the amazing thing we can do when we all work together. Really do love this community . Hope this helps someone out. If it does remember to give lakobos a big thank you.
I have tried this new feature coming with the stock Oreo ROM and received a message from my mobile carrier initially, welcoming me to WiFi calling. All network settings seemed to be working fine, I was also browsing internet with no problems, all apps were connecting and responding as expected. However the first time I tried dialing one of my contacts I've got a message "Server error. Try again later." on the dialing screen itself. It looked like the call couldn't be connected. This happened to all outgoing calls, I suppose to all incoming also although I couldn't confirm that.
I tried many things like restarting the phone, turning data on and off, going into flight mode and disabling it, in the end I reset all network settings disabling LTE advanced services before doing that and enabling them again after the reset, but I still get that error. If I disable LTE advanced, all calls get connected with no problems.
Does anyone know if this is something with a list of supported devices explicitly enabled by the mobile carrier in their network? I am considering calling my carrier for more information but the fact itself I have got a welcome message means the device has been detected as part of the advanced services network. Perhaps there are some network settings I need to enter? Anyone ever used Axon 7's WiFi calling/advanced LTE features on any network?
Does that maybe include VoLTE which the carrier may not support?
https://www.4g.co.uk/what-is-volte/
Well according to the link provided and what I know, LTE is supported by my operator, but I wonder if it needs to be specifically tailored to a phone model by them and/or the 8.0 update by itself is not providing such functionality or it is limited by default. And I think it may be the first since ZTE products are never on the list of supported phones by any operator. But I couldn't claim it for sure as otherwise ZTE would not have included it at all with the 8.0 ROM and there are so many basic or very old models like LG K8 or Microsoft Lumia 550 that are supported.
Has anyone tried using "LTE advanced" on their 8.0 yet?

LTE Advanced = Volte
If your carrier does not support Volte, keep this option off.
WiFi Calling is something separate and not related.
If your carrier does not support WiFi calling, keep this option off.
You should still get LTE service with both of these options off. I personal find WiFi calling to work poorly, so I leave it off even though my carrier supports it. (TMobile US)
Also, there is a Q and A section for these types of posts. Don't post questions in the Guides and News section please.
Thanks for the input. Both of these options are reported to be supported by my carrier on their website. Also I always had LTE before 8.0 so simply wanted to try the new "HD voice and advanced communication service" as described in the latest firmware.
About posting this thread in the news & discussion section, this only relates to Oreo which was only recently released to the public so it is a completely new feature for the Axon. Most of the other threads are too general and since there will still be many people with 6.1 and 7.0/7.1, I would have hardly got any response whatsoever in there. For now I will keep this new option off and will contact my carrier for the support of the Axon and ZTE in general.
Hey guys been trying to enable VoLTE on my device it the international version CPH1919, I've tried *#*#4636#*#* and went in there and I see it but it's not turning on it just stays greyed out. Can anyone help ?

I am looking for the same solution. You have achieved it?
I have the same model and I can't get the code to work in the stock dialer. How are you guys getting to open up?
Thanks

Same here. If you just want to access the network settings you can download an app like "ForceLTE" or similar.
I'm facing the same problem, I am appreciated if anyone have the solution?
Check your carrier and location
Whether you can use VoLTE or not depends on a few things:
* Your location, your account with your carrier, and the model of your phone.
* The carrier, carrier account, location, and phone model of the person you're calling.
* Some carriers support VoLTE only in certain cities or area codes. Contact your carrier to ask about your area and account.

Thanks for your reply, the problem is I have no problem to have VOLTE by using Galaxy S10 with same sim card and I couldn't find the volte "switch" in the oppo UI and couldn't turn on/off. As a result couldn't use the VOLTE function. Therefore I do think it is the firmware problem from Oppo.
I just thinking about if I could flash the official Taiwan rom of same global phone model to my current one for solving the problem. But I'm not sure if it is workable or not.

Ah. I have CPH1919 (UK) and only option is call over Wi-fi. There is also no way to get to the hidden service menu either like in every other phone I've had.
If you know for sure that Taiwan firmware has it, then I suppose, in theory, it would work providing that it is also definitely CPH1919 - any other variant has different partition structure. Be careful. Read around and let us know. Good luck
I have a CPH1919TW, it's using the same global firmware as CPH1919EX (even Oppo TW provides CPH1919EX ROM for download), the phone will ID itself as CPH1919TW.

May I know if your phone have the VOLTE enable switch in the network manual?
I recently purchased a refurbished phone Samsung Galaxy S21 5G. I just got it yesterday, and found that I am not able to use my mobile network. The sale said it is factory unlocked, and according to the descriptions, it should work just fine with my US Mobile SuperLTE network as well. When I switched on the phone, I see Verizon on the screen and so, I assume that it was locked to Verizon in the past.
When I tried to change the network settings, specifically the APN settings, I get the message "Access Point Name settings are not available for this user." The three dots on the top with reset to default is also greyed out along with Network mode in the previous page. When I click Network Operators and try to connect to the network manually, I am only able to connect to Verizon Wireless and no other. But, calling and messaging seems to work fine. Is it that the unlock process has not been completed properly? Did any of you face the same problem before? It would be great if there is something that I could do to unblock the APN settings as the rest of the phone works really well. The specific model is SM-G991U.
Thanks!

So, you need to go into the settings menu and find about phone, software info. What you want to find is the CSC information.
It will basically look something like this: XAA / XAA-XAA / XAA (or some other letters like VZW or ATT or TMB etc etc.
What taht will tell you is very helpful in determining what rom the phone is running and what kind of device it was originally. Find that in your device and post it and people will help you to figure out what it means.

Thank you so much for your reply. I looked through the software section in the about section. I found the following codes about the rom.

So the csc info is complicated, I'm no expert on it. But it does look like the OYN indicates it's a multi csc rom. It does have XAA as a part of the code, and that indicates it's 'open' for that specific part. But all the others are VZW. So it's running a vzw rom, obviously.
Your sim US Mobile uses both verizon and t-mobile networks. So it working for calls and texts makes sense, as a vzw phone. You could use patched Odin and flash a different (open) rom, but first you should verify that the device really is unlocked from vzw.
Best way to do that would probably be to insert another carriers sim card and see if it can make calls / texts. If not, it's not unlocked. But are you saying everything works now except mobile data? IOW, no internet access?
I had an international sim card at hand and I put it in. Interestingly the APN settings are no longer blocked. But, I do get a notification from setup wizard saying the inserted sim is not from Verizon and some services may not be available. But, messaging still seemed to work and I was also receiving 4G.

Oh then yer okay. That message from verizon can be gotten rid of a couple of ways; 1) use adb commands to disable the specific packages 2) use patched Odin and flash a different rom
VZW is the only rom I think that does that, and it's very annoying. I don't remember exactly which packages have to be disabled, but search google and use xda and vzw in keywords and u should find it.
The 2nd option would be my choice. It would do away with vzw crap and with an open rom you may find volte and vowifi will work also.
cheers
Thank you so much for your reply. That sounds great! To just give it a try, I tried putting in a TMobile sim and phone restarted to install software for TMobile. After that the APN settings were unlocked and now I am also able to connect to the internet using my US Moblile sim. The only problem is the the network mode is greyed out.
This rom I think only recognizes network from major telecom providers. So, just flashing with an unlocked rom would just help to unlock all the features and also remove telecom specific crap. I will try to flash it today.
Thank you again!
I also just flashed the stock firmware which is fully unlocked. And there is no bloatware from telecom OEM's. I am now able to use the network and set the APN's, but the Network Mode is still greyed out. Is it possible to know why? I am guessing that if the phone is fully unlocked, I should be able to change the Network Mode. Is there any other info that I can give you to help understand what is happening? I do not see vowifi as well.
So I have a US Xperia 5 IV. It is on the current latest official firmware from Sony my provider is Google fi. The phone is activated and working I have 5G service my Wi-Fi calling works the issue I have noticed is if I'm in a phone call my data doesn't work while I'm in the phone call.
If I enter the phone test menu and look at phone information it shows me that volte is provisioned. The IMs provider even says that it's registered and that volte is available but it's almost acting like the phone isn't actually doing volte that's what I'm in a phone call I don't actually have the HD icon indicating that it's on a volte phone call.
I looked around and the only other reference of someone having the same issue was one Reddit post but nobody ever answered them and a few other people have reported the same issue on that same Reddit thread. Things that have been attempted by me and the other users is we've disabled 5G cleared the Google fi app said it back up anyone have any clue what might be happening or how to fix it?
I have the same problem....but i am on a different network

I was going to attempt to go through the volte vowifi guide that someone posted here but only do the volte and see if maybe that would Kickstart it and make it work.
I mean it shows in my phone that volte is on so thats not the problem .... Is probably something in firmware thats fcked up. So i guess a13 might fix it

Yeah my phone it shows the same thing and the phone information screen it's provisioned ims shows registered and available it's almost like the phone software just doesn't want to switch over and do that.
It could be the firmware is anyone know if the Xperia 1 IV has the same issue?
