VoWiFi - Xperia Z3 General

Hello!
Newbie here. First post. Have been lurking around regarding Sony's refusal to unlock WiFi calling (VoWifi).
I have a Xperia Z3+ dual sim (E6533) and I am interested in WiFi calling because I don't want people to know when I am out of the country. Dialing 800 numbers (three work numbers I need to use are 800 only) also works when using WiFi calling outside the US. My previous Xperia was a unlocked t-mobile single sim model. It was great until it died. I didn't know that WiFi was a t-mobile only thing and now I am stuck with this dilemma.
I played around with the hidden access menu (#*#*4636*#*#) and I was surprised that WiFi calling is possible but deactivated (under phone info). Activating "Wifi Calling Provisioned" doesn't do any good, since it goes back to OFF once you access the menu again.
Anybody know if it IS possible to activate Wifi calling? Is this a phone or carrier restriction? Is there a firmware mod that can eliminate this restriction?
Thanks!

Wi-fi calling on the Priv on EE

BlackBerry say there's a setting for enabling or disabling wi-fi calling.
"Swipe down from the top of the screen once using two fingers, or twice using one finger.
Tap The Settings icon > More > Wi-Fi calling.
Turn on the Wi-Fi Calling switch.
To see when your device will make Wi-Fi calls, turn on Wi-Fi Calling Status.
Tap Wi-Fi calling preferences > Connection preferences.
To use a Wi-Fi network, even when you have a cellular signal, tap Wi-Fi preferred.
To never use a cellular network and only use a Wi-Fi network, tap Wi-Fi only.
To only use a Wi-Fi network for calls when you don't have a cellular signal, tap Cellular network preferred."
I have checked in vain for the above settings even though I got text from EE saying wifi calling is enabled on my phone when I first set it up. Is this a carrier specific setting or are blackberry telling fibs?
FYI - I have an unlocked PRIV US version and use it with T-Mobile and I do have WiFi calling.
Thanks it would seem EE in the UK have blocked the setting.
I'm from germany and for me the setting is also blocked.
There is no such setting option in India. I can't find it on my Priv

It's carrier specific, and glitchy as hell. Good luck to you.
EE Rom for Priv?
Some thieving toerag lifted my Google Pixel XL (which I was extremely happy with ) and I only had insurance on my iPad (I know, no point calling me names, I've already called myself everything under the sun!) So I had to get a replacement. After a few duff cheap ones which I returned, I got the Priv from Amazon (SIM free) and am amazed that a nearly 3 year old phone (even though brand new) was so feature rich and so well made. I'm chuffed to bits. EE(UK) sent me a replacement SIM and all systems go....except with WiFi calling. EE have confirmed that it needs to be one of their ROMs for the WiFi calling to work, and I'm really struggling to find a ROM for it. Don't suppose anyone else had any joy, or workarounds? Plan 44b is to get a cheap (£30) non branded Wireless Repeater with an 10m aerial cable you fix on the roof, and a small control box and internal antenna which will work on all mobile networks. I don't mind doing that but it's gonna take about 3 weeks to get here from China, and I was hoping for something a little faster - rubbish signal in my area and can't connect to the EE booster box!!

Using wi-fi calling on a G900A on T-mobile

I just now switched from AT&T to T-mobile because I finally got sick of AT&T for various reasons including very high prices. The network lock is removed. How can I get wi-fi calling to work on this phone? When I try to enable it, I get "To enable this service you must confirm your emergency address.". Then I see "Wi-Fi calling lets you make and receive calls over Wi-Fi with your AT&T account. When you use Wi-Fi Calling, information about the country where the Wi-Fi connection is made will be sent to your carrier. Learn more about Wi-Fi Calling.". The last two words are a link to https://m.att.com/shopmobile/wireless/features/wifi-calling.html?referrer=. It seems there's a hangup of AT&T versus T-mobile. What should I be doing to get this working?
In case anyone is wondering, this particular phone is being used because it must be kept unrooted. I have a G900T that has been rooted.

T-Mobile wifi calling possible on unlocked S7 Edge (SM-G935U)?

I have an unlocked Galaxy S7 Edge (SM-G935U). My carrier is Total Wireless (Verizon MVNO). I recently got a new office at work, and the Verizon coverage in this part of the building is terrible. I use wifi for data but cellular calling basically doesn't work at all.
I've been looking at other networks, and I'm leaning toward T-Mobile or MetroPCS, one of the reasons being they have wifi calling and the wifi at my office is plenty fast. I checked in settings to see the wifi calling option, but when I go to settings > connections > more connection settings, which is where the wifi calling setting is supposed to be, there's nothing about wifi calling.
I had a thought that maybe the wifi calling option isn't there because my current carrier doesn't support wifi calling, so I contacted Samsung support. I asked if I get a SIM from a carrier that supports wifi calling, would the wifi calling option be enabled. They said that unlocked phones don't support wifi calling at all.
This confuses me, because this thread mentions some people were able to use T-Mobile wifi calling on an unlocked S7/S7Edge. But that thread is older, so maybe for some reason wifi calling was removed from the unlocked S7 Edge with the Nougat update?
I suppose the only way to find out for sure is to get a T-Mobile or MetroPCS SIM and see what happens. But is anyone able to shed some light on if this is even worth trying? I suppose it's also worth trying out just to see if regular cellular calling on T-Mobile might be fine at my new desk, but hopefully there's some way to do wifi calling.
Unfortunately I think you need the sm-g935f to get t mobile wifi calling. Don't think it was ever achieved on the U models
I had an s7 edge from T-Mobile (SM-G935T) but I flashed the unlocked firmware essentially making it a SM-G935U and I had VoLTE and Wifi calling working with no issues. It was about a month ago, so it was on Nougat. I would expect no issues with an actual SM-G935U on T-Mobile.
Well, I answered my own question. I switched over to the T-Mobile 10 GB $50/month prepaid plan and when I changed SIMs the phone gave me a "reconfiguring your device for new SIM card" message. Wifi calling is now active.
Also, this is a list of phones that support T-Mobile wifi calling. I probably should've checked here first.

Complete debrand of LG G6

I was wondering if like Sony and Samsung devices, if it's possible to completely debrand a G6 to enable Wifi calling and VoLTE on a specific network's branded software? I know the G5 left the original operator's customisation files (unless rooting to change the cust folder) but has this changed with the G6?
Haven't bought the phone yet but seen an unlocked one which obviously wouldn't have network branded software.
Thanks.
Not sure of the purpose of this. So you want a completely unbranded phone and then want to install a specific network's software for wifi calling and VoLTE? If so, why not buy the phone from that network? Example: I bought an unlocked T-Mobile phone (on Amazon, not directly from T-Mobile) that can be used on any network, but contained T-Mobile software. I disabled what I didn't need. I am on T-Mobile anyway so I can use their wifi calling app.

Purpose is that a second hand unlocked phone is much cheaper than one branded to the network at the moment.
wifi calling is mostly junk and over-rated feature. I know of no phones that can do a decent handoff in the event that wifi signal drops out of range then the phone wants to continue the call on LTE but if your LTE signal is already weak the call will just drop. Happened to me all the time so I just disable it and all the HD voice garbage too. Forcing back to the old 4G network thats now less congested than its ever been!
Admittedly wi-fi calling has only come in useful a handful of times, but the 4G calling feature has worked for me in a few places where 2G/3G is patchy. Guess I could do without it though.
Install Google Voice, hangouts, and hangouts dialer. Then you can use Wi-Fi or data calling in any phone or any rom.
I'm using a US997(16a) in Verizon and it works fine.

Thanks, had those installed on my G5 but never used them. Will give it a go.
I switched from an S7 Edge, on which I was able to change the CSC Code and get features different Canadian Carriers had to offer. The particular one I was interested in was VoLTE(Video/Voice over LTE) video calling was the main feature I wanted to keep. That's why when I switched to the G6, I made sure it was from Rogers so I can continue to use that feature. It's pretty sweet... great quality video calling without using any data
I wish LG had a feature like this too, where you can change carrier settings on unlocked phones. It would be helpful
It would indeed be helpful! I guess I managed fine without the features before and it's not a huge loss but wi-fi calling definitely came in handy at a couple of places I used to work at.
IME Samsung and Sony phones were fairly easy to fully change carrier firmwares on and I remember HTCs being a pain (not sure what they're like now). But LGs seem to be able to debrand 90% of the firmware but still leave enough of a trace of the original software to block off a couple of features, which is slightly annoying. Ah well

VOLTE Wifi Calling with Unlocked S10+

Hey there, I've been doing a bit of research but it has been a long while since i have done any flashing of firmware etc. I received my s10+ device today. Model number is SM-G975UZKAXAA. I am a Verizon wireless customer. When I placed this device on my account I noticed I have no access to Voice over LTE, and I also do not have any access to Wifi Calling. My question is the following. I read somewhere a couple of weeks ago that if I wanted something like this I would need to flash the original VZW Firmware which would have all the lovely bloatware etc on the device. Is there any way I can do that? I have seen firmware that has been posted but I dont seem to see anything that specifically is the VZW apps etc which should (hopefully allow VOLTE and Wifi Calling and maybe even HD Calling, if thats a thing)
I would appreciate any info anyone can provide me on this, as the only solution I can see at the moment is to return the device and start over with a VZW specific device.
Cheers~
Likewise but with a T-Mobile firmware for me
Unlocked US version here with Verizon and wifi calling and volte working out of the box.
You may want to call Verizon to see if they need to provision it for your account.

Hey guys, just wanted to check in with you (or anyone else who has wifi calling on unlocked Verizon). It is 100% working? It's the only reason I got the carrier version. Should I cancel and order the unlocked?

Yes, it works with my unlocked S10+ on Verizon. It surprised the heck out of me as I too have the unlocked Note9, but no wifi calling.
What about on AT&T? Can anyone say if they can at least get VOLTE? WiFi calling would be the icing on the cake. Thank you

Wifi calling worked on my unlocked S10 out of the box on T-Mobile. I'll try and check on VoLTE later but I get **** reception near work.
Can you explain how you enabled WiFi calling on unlocked version, on Verizon? I can't find a way to do it. What about HD Voice? My real problem is that data does not work while on a call, using my unlocked, on Verizon. Is there a way to get that working?
I have unlocked S10+ on VZW. I get LTE+ which is VoLTE, data works while on a call.

I don't think that is right. LTE+ and VoLTE are different things. As well as data while on a call.
VoLTE means your call is being transmitted over LTE. I'm pretty sure you can use data while on a call WITHOUT VoLTE.

How do you test if VoLTE is working? Do you get an Icon for it?
I tested WiFi calling by going into airplane mode, turning Wifi on, and making a call and it worked. But didn't get a special icon for it.
For those basing your decision to buy unlocked/international vs branded, be warned. I can only speak for Att, but I spent about 2 hours arguing with their level 2 tech department and here's what I have learned. If you have a sim that is provisioned on a branded phone and then put the sim into an unlocked/international phone, you will be able to use volte, wi-fi calling, etc., but only until the carrier pings your imei for a periodical check, once that happens, those features disappear. Also, on Android Pie, the Enhanced LTE Services tab under Mobile Data has been removed as it is turned on by default, also confirmed with ATT. The only way to manually check is to toggle wifi calling on and see if it works. Anyway, just trying to help as I have gone to a branded phone for the first time in 6 years because the reception and enhanced features are more important than rooting to me.
I was able to get wifi and volte working on my unlocked s10 by putting sim into verizon phone, letting network recognize it, enabling advanced calling and such on that device and then taking the sim out and putting it back in my new unlocked s10. The option for volte appears in settings-connections-mobile networks.
VoLTE works on tmobile, not that anyone should be surprised. That has been the case for the S8 thru N9. Now... I noticed that Samsung removed the VoLTE toggle from settings.

Correct, no VoLTE setting on my unlocked S10e, but it is on by default it seems

Using what I learned in this thread, I called Verizon and talked to Level2 support. They tried to get everything working and could not - but this was when I had the new SIM installed, provided by Samsung when I got my S10+.
So because others here spoke of their 'other' SIM, I suggested we try that - so I plugged in the SIM from my S8 and asked them to reprovision everything. They did... and....Now everything that didn't work ... WORKS.
So I have an Unlocked S10+ on Verizon that has (among other things):
- Wifi Calling
- Real Time Text
- VoLTE ("HD Voice") (Which means data now works while I'm on a phone call)
- Visual Voicemail
So it seems the Samsung SIM was part of the problem, and they are reporting this to Samsung. The tech support person told me others have reported similar issues and they will get with Samsung to figure out what the issue is.
Hopefully this helps some others as well!
