Well, as far as I know there is no hope...
I am in the same situation.
I wanted to have the chrome unlocked version, exclusive to Carphone Warehouse in the UK, so I got mine from CW.
I had many chat with EE and they say that most modern / recent phones support WiFi calling out of the box BUT not the XZP... It has to be purchased "direct" from EE so that it has the firmware that enables WiFi calling...
I asked to Sony support Why they don't include WiFi calling settings in their firmware, as Samsung, Apple, HTC, Huawei, Microsoft,... Do? . They simply replied that this is not their responsibility but the one of the operator... I, don't care!
So, the choice is simple :
XZP unlocked in chrome and no WiFi calling or EEocked black phone with WiFi calling...
I have 28 days return with CW... But will stick with the unlock one. Perhaps in the futur I will flash the EE Firmware, but for now, I don't use WiFi calling enough for that...
With some hope, but unlikely, maybe Sony will include the WiFi setting in their future firmware (if enough people ask for it?)

You dont need to buy direct from EE. It is enough if you just flash the EE version of the image on it https://xpericheck.com/cda/1308-6282
Check around in the forums how the flashing can be done.

Indeed, I could flash an EE firmware, but not sure how to troubleshoot if things go wrong !!! hence I will wait a bit longer for that... (and waiting for the ROM to be widely available.)..

My XZP is from O2. Ive got it unlocked and both O2 and EE wifi calling working. My operator is EE but it was cheaper to buy it from O2.

CW phone is unlocked to all networks so it has different firmware than branded unit. Look around for EE or O2 firmware to get wifi calling enabled.

I've just flashed EE firmware. Wifi Call works even better.

If Vodafone list it as a compatible handset when running their firmware then I don't see why not.

I would like to try this. But my phone is already setup and without root I can't use my trusty Titanium Backup to backup and restore all my apps and settings. A couple of questions I hope you have time to answer:
1. What flash tool did you use to install this? I found the firmware with Xperifirm, but it doesn't look like flashtool-0.9.23.1 is compatible with our phone yet.
2. Did this wipe your phone?
3. Does this firmware come with any EE branding or bloatware?
Thank you for your time.

@robdevil
What are the differences between the EE and Customised UK firmware?
Do you have a EE splash screen when starting and any EE bloatware / limitation?
I am also on a carphone warehouse phone and wondering if I should flash the EE firmware to get the Wifi calling ( I have it enabled on my EE account already and was used to use it in the past on a different phone)...
Thanks.
Tony.

Customized UK loads "telefonica_UK" configuration for any SIM inserted, which means no VoWIFI(wifi calling) or VoLTE. You definately need operator based firmware flashed to get Wifi calling and/or Volte.

No difference at all. My EE app is preloaded I think. That's it.

I can confirm this. The only differences that I noticed was the myEE app. And outlook security instead of avast security. I can't find the wifi calling setting in the EE rom though. My provider is supposed to support it, but I don't see any settings in the rom to enable it.
Edit: I checked with my providers app. It shows that wi-fi calling is not supported on my device. I'll try the O2 firmware to see if that works.
Edit2: Actually, I see the O2 firmware is still on the July security update. Security is more important to me than wi-fi calling. So I guess I'll just keep running the EE firmware.

Are you on EE pay monthly plan? You wont get WiFi Call or VoLTE if you are on Pay As You Go. You should see wifi calling settings if you flashed it correctly on both O2 and EE firmwares.

Hi Rob,
Thank you for taking the time to respond. I'm not on EE or O2. But my provider started to offer wifi calling on some phone models. Even if not purchased from them. For example the Samsung Galaxy S7 has it built in. But they don't support the Sony by default because it doesn't come with wifi calling built-in. So I thought it might show up with the EE or O2 firmware. But it didn't. I just need to go to my providers service point and ask them to force enable it for my phone to see if it works.

ishemes, so what provider you are using then and in which country ?

I'm with the provider Partner (used to be Orange) in Israel. Unfortunately they don't carry the Sony Xperia XZ premium phone. So no official support. The generic Israeli firmware does not have wifi calling in the firmware.

Quick Question
Sorry to jump on a slightly old thread...
I bought a Sony Xperia Z3 Compact for my other half. Brand new from EBay, unlocked, but doesnt have the Wi-fi calling feature, so from what I could find on a forum on EE it seems the Z5 compact has Wi-fi calling (the forum is giving instructions on how to turn it on specifically for teh Z5 and Z5 compact)
Only, reaeding this forum about phones having to be bought from the carrier to use the Wi-fi calling, I am now wondering am I going to be wasting my time buying a refurbed Z5 off Ebay, unless its locked to EE?
Thank you for any help!!
Gemma
P.S. I am the sort of girl capable of flashing, however i'd prefer not to have to do this, because I don't like interfering if I dont really need to

You might get more help by posting in the Z3 Compact or the Z5 Compact forums.
The way it works on the XZP/XZ1/XZ1c is via a set of settings overlays that are in the OEM partition.
Sony puts out different firmware for different carriers and the carrier specific items (like VoWiFI and VoLTE) are contained in the OEM partition contents of that carrier specific firmware.
If the Z5/Z5c work the same way, you should be able to get any E6653 (Z5) or E5823 (Z5c) model phone and download the EE customized firmware with XperiFirm and flash it to the phone. It should be the same as having bought the phone directly from EE with the same features and bloatware.
Again though, I don't have the Z3/5/c series and haven't dug into the firmware images, so you should check in with the people in the forums I've listed above.

WiFi Calling on Factory Unlocked S8+

A couple of weeks back, I purchased a factory unlocked S8+ Model #G955U1, Baseband Version G955U1EU1AQE3 (The AT&T Galaxy S8+ has different Model and Build #s), inserted my AT&T SIM card and have been using it since. Then I decided to activate WiFi calling, however, unlike my wife's iPhone 7, my Galaxy does not have the option to enable WiFi calling (this option should be under Settings>Connections). After some research, I found out that this a carrier feature which AT&T must provision. When I asked them to do it, they provisioned it on my wife's iPhone 7 but not on my Galaxy, so I called them again and asked them to provision it on the Galaxy. Although they insist that they did, the feature does not show up on under AT&T Devices (It shows up under the iPhone but not the Galaxy). After spending no less than two hours speaking to three agents, I learned that AT&T does not have in their data base the IMEI number of the Galaxy because it was not purchased through them. So obviously, not having an IMEI number, the WiFi calling feature is not going to be pushed to my Galaxy. Not being able to solve the problem, they escalated it to another level who is supposed to contact me two days from now. A friend purchased his Galaxy S8+ through AT&T and the WiFi calling option is there in Settings>Connection and he is able to toggle it on or off. When I used AT&T's IMEI Verification tool, the result was "Device is compatible but we cannot find matching SIM card".
Any and all input would be appreciated.

Same here. Looks like wifi calling is not a feature that is available on the unlocked version unfortunately. Same with using LTE while on calls and built in visual voicemail :/
You have some advantages going unlocked but you lose some things too.

But you can always use Odin to flash the ATT firmware to the unlocked device. There's plenty of threads here regarding this very subject.

True, just keep in mind that future att updates can't be done via OTA - which can be a pain too.

With the unlocked s8+ i've found that wifi calling and volte only worked on T-Mobile, I tried it with T-Mo and verizon. It stinks that ATT cant be more like T-Mo with accepting non branded devices

I am pleasantly surprised and a bit puzzled because when I spoke to T-Mobile Tech yesterday, she could not confirm if WiFi calling will work on unlocked S8+. If I can be assured that it will work, I will switch to T-Mobile.
Please do me a great favor and check if your unlocked S8+ has the same Model and Build Numbers as mine. Here are my numbers:
Model #G955U1
SM-G955UZKAXAA
Baseband Version G955U1EU1AQE3
Thank you.

All the information you provided matched with my phone. As a matter of fact, I also tried my friends SIM who is on MVNO called Mint Mobile that runs on T-mobile network. Mint also allowed me to make wi-fi calling. I am surprised that t-mobile rep could not confirm this feature because this feature is on by default! If I don't want to make wifi calls, I have to turn it off. The only little annoying part is that you get constant notification," Calls will be made over WiFi". Even when you block this notification, it will reappear on the reboot

Thank you indeed for your response. When I got my S8+ and before inserting AT&T SIM, this feature was NOT listed under Settings>Connections. I was informed by a Samsung agent that the carriers will push this feature to the phone through their SIM after they provision the feature. So now since my SIM is AT&T and my phone is unlocked, and its IMEI number is not in AT&T's data base, I don't have the feature listed.

Unfortunately, I can't comment on at&t network. On t-mobile, I did not have to do anything except during the initial setup, I was asked if I was ok to make wifi phone calls when a wifi connection was available & the signal was strong. I still have the option not to use this feature. You may wantvto visit a t-mobile store or find a friend who is on t-mobile network. It might not be a bad idea to reset the phone (after backing up) when you get the new sim card. Good luck ?

I switched yesterday from AT&T to T-Mobile and immediately the wifi calling showed up in Phone Settings as you mentioned. However before switching from AT&T to T-Mobile, wifi calling was not anywhere to be found.

That's because WiFi calling and VoLTE are not available on ATT using the US Unlocked device. You have to either buy an ATT carrier version, or flash the ATT firmware to your current device.

Try to reset to factory defaults with sim inside
I'm on Argentina and with unlocked software i got wifi calling when the device is set up with my sim inside

I found that after wasting several hours with AT&T's techs. The 3rd option is to dump AT&T and switch to a carrier that has wifi calling available for unlocked S8/S8+ phones such as T-Mobile.

To access Wi-Fi calling you need to open your phone app and hit the settings button in the top right corner and then scroll all the way to the bottom and it will be there.

S9+ Exynos on T-Mobile US Journey.

Just received my S9+ 256GB Korean Variant SM-G965N. This is going to be my experience with this particular variant and its compatibility with the T-Mobile network. Currently it shows I'm connected to Band 2 LTE but the speeds I'm my area are very slow. Withing the next couple days I'm am going to test the network throughout my area in Cali and test speeds and connectivity and report back. Unfortunately the build of Samsung pay is customized for S.korea only and not compatible here in the US.
Current build after first update is G965NKOU1ARC7
Baseband versions G965NKOU1ARC4

I have some data speeds this afternoon while out driving. The long screenshot is from my G965 and the short list of from a T-Mobile variant S7 . Connection to the network itself has been stable with no notice of dead spots or issues switching towers, if anything I'd say the switch is faster from what I've notice between devices.

Excellent...a lot of us have been waiting for this...thanks for testing...

I was curious about this. I have a G965U1(S9+ Unlocked North America variant).
I have a second phone with Ting GSM(T-Mobile), and I tried a few speed test. The phone configured it self to send calls over wifi when ever I connect to wifi. I found that peering with Sprint appears to be an issue.

Hey guys,
I also got an international S9+ (SM-G965F) but from Germany Unlocked (DBT). So far the signal seems to be great. Will post some Speedtests later. The only downside is that wifi calling and VoLTE is not there. It was working with my German sim. Other than that it's been great.

Have you flashed T-Mobile CSC? I assume you have to root and make a custom zip to flash the files. If the phone thinks it's a legitimate T-Mobile phone then it give you full speeds.
Also is the Korean phone a duos? Dual SIM?

I dont think that is possible. Isn't the Korean version run on Exynos? Flashing a Snapdragon CSC for TMB would be wonderful but I think would mess lots of thinks up. Hopefully someone will be able to change the CSC to work on the exynos processor.

Okay so the weirdest thing happened to me. I tried to use Samsung pay a few days ago. I used app cloner to copy the working version of my note 8 snapdragon and sent it to my S9+. It didn't work and gave me the connection error. Now I was just on the phone and out of boredom I tried to open Samsung pay again while on the phone and it magically worked. It asked me for my Iris and fingerprint and I was able to add my cards again. Again, this is on exynos DBT from Germany without any modifications or OEM unlock.
Hope this will help at least with Samsung pay.

Yes am looking into seeing how I can configure the CSC to achieve full T-Mobile speeds. The Korean variant in not a duos.

I have a friend that works at Sammy S. Korea that picked it up for me, as for Samsung pay the apk is specifically built for the Korean market and has a different activation process which requires a text from one of the local carrier networks which I cant bypass.

The build is completely different and won't work because of the region and coding in this software build. I am not ready to root yet so I'm going to tinker with software that's official and see what I can get working, improve on for now.

Not really. I'm also on T-Mobile USA and have the German exynos. The apn settings were loaded correctly. Maybe check them in the settings and make sure it's set correctly. The only thing that is not working is VoLTE and wifi calling.
Samsung pay finally works with the credit cards but the membership doesn't work.

ow did you do the initial setup with or without the T-Mobile sim inserted ? I noticed when I originally set my Korean variant up without the sim, for some reason I did not connect to LTE in my area and after oem unlock and restart/ full wipe it connected perfectly since.

I've got the same model, I'm with ATT, speed test shows 31m down and 10m up, but actual downland from play store is less than 2m...

Hi do you receive benefits in your samsung members app?

Yes if we can get T-Mobile CSC settings to enable VoLTE and Wifi calling then I will root.
I am recently realizing Samsung Pay is not everything it's cracked up to be. It doesn't seem like they have many 3rd party companies registered, so I made a custom loyalty with the barcode, but it doesn't work when it's scanned at checkout. Funnily enough, I have the loyalty in GPay as well, and it works just fine. Also SPay doesn't seem to work in gas station cc readers where you stick the card in and pull it out instead of swipe. Unfortunately it just doesn't seem like the technology is there yet where we can ditch traditional cards.

Unlocked Pre-Order from Samsung w ATT SIM - will I be able to use WiFi calling /VoLTE

Current Note8 user on ATT (phone locked to carrier). I pre-ordered a Note20 Ultra from Samsung direct, unlocked version. Have been off XDA really for a couple years and not rooting/modding much lately but have read that ATT will not allow unlocked phones on their network to use WiFi Calling and/or VoLTE. If true, are there workaround options for me (assuming I stick w ATT as the carrier I mean) to get these to work, or should I cancel the unlocked model and order the ATT version? Was hoping to root eventually and remove bloatware / play w custom ROMs again on the Ultra etc etc. - that is why I ordered an unlocked version.
Thanks gents for the guidance here! Best forum around for us phone geeks

If it will be like Note 9 or 10 plus just have to flash the U version csc with odin and it will give you wifi calling advanced..messaging..volte

Much thanks - I will do this then when it arrives.

Did not work for me on the unlocked note 10+. Worked right away on the tmobile.
Att was actually fun to have. Nothing that att expected worked on the unlocked device. For example I had unlimited hotspot, despite it was not included in my att plan.

That's bizarre. I am rethinking this unlocked route. I must have wifi calling since signal at the house is terrible in my area. I don't need the drama of uncertainty if this will work or not. Might as well cancel the unlocked one and just upgrade via att. Oy. Wtf is with att these days? They lost my directv account last year and now their wireless policies are looking like a royal pita.

I don't think you have to worry .... ATT seems to consistently allow Samsung unlocked devices to have carrier functions
You just have to flash the U CSC as mentioned above. Worked for me on Note 10 and is currently working on a s20 ultra device

Whats going on buddy. You jumping on the Ultra?

I strongly recommend switching your order to the ATT model. I got my note 10+ unlocked based off the suggestions found here saying that flashing the att firmware would give me all the features, and I've been through a year of headaches.
For a little wile i was able to enjoy wifi calling, voicemail and VOLTE, but after my first software update the features were lost. i was able to get them back briefly by putting my sim back in an old Att phone and keeping it for a day or two, but that trick never lasted past a week. I've tried re-flashing the software, switching back to unlocked and then back to ATT, basically anything i could think of and it never worked.
calling ATT didn't help either, as the reps gave me a canned line about not supporting outside phones. the whole reason I'm updating to the 20 ultra is to just get my phone fully functional with an ATT model

Thanks darth. Yeah, I switched to the att version. Hate the hidden tracking bloatware etc that comes with it but must have a very workable phone for daily work calls and wifi calling is a must. No drama is my motto these days. Thank you for reporting your experience.

I had the same situation with my unlocked Pixel 4 XL, keep calling ATT until I got the right person to modify my sim to allow WiFi Calling to work, that's my plan when I get my unlocked 20 Ultra.

I'm not a gent, but I doI have the Note 20 Ultra in for review and am using it with an AT&T SIM. VoLTE works, no option for WiFi calling.

What worries me is the 5G. Will unlocked work for ATT 5G?

It does on my unlocked Galaxy S20+ 5G. The Note 20 Ultra is a ways to release and their system doesn't yet correctly identify the IMEI, so I can't say for sure what will happen after release day.

Hi Lisa,
Your reviews are the best, so thank you first of all. Can you check if it has any eSIM capabilities? Supposedly S20 was going to get an update to allow eSIM use in US but that never happened...

Thanks . I'm not seeing anything under connection settings on our US unlocked Note 20 Ultra (there's no IMEI listed or cellular network option listed under connection settings when no nano SIM is installed. EsimClient is running on the phone, which makes me think the hardware must be there. EsimClient is not running on my GS 20+ unlocked.

Great, thank you for checking and comparing with S20+ !
eSIMClient running gives me hope that we will get eSIM support in an update...Still perplexed how or why Samsung has gone out of the way to disable eSIM on US variants when Apple, Google support it.

Ha! Thanks Lisa (love your tech vids!!) - I switched to the ATT version. Supposed to be here 8/21. I can't take a chance with wifi calling being borked, or that just that I may need to Odin-flash updates or CSC packs periodically to keep up with the monthly patches (ie force an unlocked unit to keep working on ATT's network if my previous firmware gets overwritten etc. I mean). I guess as I got older I went from a tech pioneer and adopter to just an end user LOL.... I just need it to work. Maybe I can do that package remove thingy and chop the bloatware periodically... we shall see once the community gets these units and starts their dev magic for us.
I guess I will need to make an appt at the local ATT store in a week to get on a new 5G plan from my current 4G one to take advantage of the coming speeds.

You're welcome- glad you enjoy our vids! With AT&T, you can simply change your plan online, no need to visit a store. The mid and high tier unlimited plans include 5G.

I flashed my unlocked Note 10 plus and didnt get wifi calling, visual voicemail, VOLTE.....only reason I am up grading is to get an ATT version, and to skip all the hassle of an unlocked version. Never again.

Could you tell me more. I have the US unlocked note 20 ultra, I put an AT&T sim in (from my note 9 unlocked) and I can't find an option to turn on wifi calling. I pretty much gave up on feature like this, because I would rather have the unlocked phone, but if it works now maybe I am missing something.
Thanks

Fold 2 AT&T Firmware help

I ended up buying an Unlocked Fold 2 on AT&T and now realize that there is no WiFi calling. I am looking to flash the AT&T firmware on it but I cant seem to find it. Guessing its either not available yet or I'm just dense hoping for the latter lol. Can anyone help me find the AT&T firmware to flash, thanks.

Well I found the ATT firmware on SamMobile and flashed it but still dont have WiFi calling. Anyone have any ideas or a different firmware to flash to get that feature?

Really? I didn't see an AT&T f916u firmware on SamMobile. Unless its an AT&T firmware with USERDATA file then you will not have working Wi-Fi calling.

Oh I thought the f916u1 that says AT&T was the firmware. Super glad then so there is a chance that sometime later something will be uploaded? Yeah not to knowledgeable with this stuff so just saw AT&T and thought that was it. Well I will have to check that site for a little while fingers crossed.

Guessing from past devices, once a "branded" complete AT&T firmware becomes available for the Z Fold 2 then you should be able to have the option for Wi-Fi calling of course your SIM has to also be provisioned for this feature. I think if you can wait it out, you will be able to have Wi-Fi calling at some point.

I bought a Tmobile one even though i use Google Fi (which basically uses Tmobile only on non Fi phones). I flashed the unlocked firmware SM-F916U1 and i have Wifi Calling. I choose XAA.

Is it normal for it to take this long to get the branded firmware? I'm also in SoaringSpoon's shoes, I can't get a reliable signal from where I live.

Every big US carrier but AT&T is up now on the F916U on SamFrew rn so I am hoping AT&T follows shortly. Far easier than exchanging the phone. Or what I would immage actually would happen, returning it and buying a new one lol.

It's just an AT&T thing. AT&T don't make firmwares available publicly. AT&T exclusive features like Wi-Fi calling and HD Voice aka Voice over LTE are usually not available to unlocked devices with a few exceptions like the Pixel and the recent S20 series. Fortunately for us here at XDA, I'm speaking for past experiences that there were AT&T firmwares available from either SamMobile or people here with access to the AT&T servers. Hardware wise, US Samsung phones should all be the same with exception of maybe Verizon due to their radio requirement differences. So all carriers features should work on all devices providing 1) correct software/firmware on the phone 2) the carrier's database sees the device as a capability device/system provisioned. I suggest that anyone looking for AT&T Samsung Firmwares, search the sub for maybe s9/s10/s20...see who in the past provided firmwares for this carrier, ask them. Hope this helps.

Hi I am on the same boat were you able to find the AT&T firmware for your galaxy z fold 2. If yes can you please help me. Thank you .

Is there any ways you can help me with the steps, do I need to first root the phone? I am new and does not understand too much. Appreciate your assistance.
