T-Mobile band 12 VOLTE does it work? F3113

I am @ Bestbuy and want to buy the xperia xa F3123 right now. Can anyone quickly let me know band12 VOLTE works on T-Mobile and/or MetroPCS? Thanks in advance.

Well it seems as though VOLTE does not work on this device. It's weird because the whitepaper on sonymobile site says that this device does support VOLTE. I will be returning the device if this does not work.

Yep i thought It did aswell, I'm in the UK on three UK and though I think it is network dependant too in the build prop file it does say something volte=0 it may be just turned off. Also not convinced that the white paper is even correct if this is the case.

Update: more settings
The VOLTE setting in build.prop are:
ro.mtk_ims_support=0
ro.mtk_volte_support=0
persist.mtk.volte.enable=0
persist.dbg.volte_avail_ovr=0
Can someone with root access change it to 1 and reboot your device? After this check through setting to see if there is VOLTE or Advanced Calling somewhere. Also try a call and see if LTE stays connected.

I tried all of those build.prop settings. I get the Enable VOLTE option in settings but all calls drop to UMTS/HSPA. Sony Mobile support on their forumkeep pointing to the whitepaper and blaming the carrier. I tried a T-Mobile sim and an AT&T sim. No VOLTE. I tried Bell Canada ROM and journalist ROM. Still no VOLTE. Guess I will be returning the device. Too bad because the hardware is great.

Only extra thing I find is sip calling which is over WiFi, just checked in *#*#4636#*#* it says turn off VOLTE permission flag as a setting doesn't seem to do much.

Specs according to my network three UK clearly states volte voice over 4glte strange...
EDIT: From what I can gather it's all done automatically on my network at least, especially if you use there WiFi/volte calling app called three in touch for when you have no network coverage it was originally intended as a WiFi calling app but now supports volte apparently and for now must be on my carrier firmware(more or less a customised UK ftf only there splash screen and two of there apps both needed) not that this probably helps you but it is supported(network dependant)

I just returned mine. What carrier are you on? Maybe someone can flash that firmware to see if volte works. Actually that won't work on the Americas model F3113 since baseband won't give us usable bands.

Three UK, but until I can find somewhere I can't get a normal signal I can't try it out. I've checked my carrier supports it they do, they say my xa supports it but it will only kick in when all other methods of making a call fail. Shame really, for me it's a great device

I can confirm VoLTE is working.
Got VoLTE toggle after adding these lines in build prop.
ro.mtk_ims_support=1
ro.mtk_volte_support=1
persist.mtk.volte.enable=1
persist.dbg.volte_avail_ovr=1
And changing some overlay apps and changing modem to VoLTE as well.

This has nothing to do with the xa supposedly being volte enabled out of the box on stock firmware(network dependant) . It's bound to work on a rooted device whatever the model.

It can probably work on XA, looking at build.prop and have:
ro.mtk_volte_support=0
persist.mtk.volte.enable=0
persist.dbg.volte_avail_ovr=0
I don't use Volte but it can help.

It's network dependant so even if you enable the volte toggle in settings via build prop if your network doesn't have volte you can't use it. Still trying to figure out who is right. My network advertise the xa as 4g super voice(what my network call volte) capable out of the box as do Sony yet there's no toggle or mention of volte calling anywhere in the device. Three UK reckon it'll only revert to volte calling if all other methods of making a call fail first say if your in a area with no or little reception. It's a sim free network unlocked device running my networks slightly tweaked customised UK ftf with only a splash screen and a few apps for account info and a WiFi calling app

That statement about volte as a last resort sounds backwards from how every other volte phone works. They prioritize volte. Also thanks for speaking up in my Sony Mobile forum thread. The more people bug Sony, the better chance we have of getting a straight answer. If we end up with working volte support I may purchase this device again. I really do like the size & form.

VoLTE on unlocked version

I have a feeling I know the answer to this, but is there any way to enable VoLTE on the unlocked version, notably on the Rogers network in Canada?
Thanks

Settings-->More-->Mobile network-->VoLTE calls. Enable that. If LTE stays connected when making a call you have VoLTE.

Thanks but that's what I originally feared: there is no VoLTE option anywhere in there..? I had done a search too and nothing pops up.
Rummaging through the internet, I found an article saying the unlocked version (mine) would NOT have VoLTE. No sure how accurate that was.

Are you connected to Wind by any chance? I don't think that network has volte yet. I think Rogers purchased them.

No, I'm on Rogers and I can confirm I had VoLTE before on my Galaxy S7, so it's neither the network or my account the issue.

Very weird. Maybe ask your carrier to check provisioning for your device. What bands does your carrier use for VoLTE?

it should be supported bu carrier it self , not only the phone ! check with them !

Well after some investigating, I have an answer: Rogers only support VoLTE on Apple, LG and Samsung devices...
This is really unfortunate but it's one last thing missing from the Honor 8 to make it my daily driver. It's an excellent device and I was very impressed for the price tag, but not having wireless charging, VoLTE and 4k video made me realize how much I actually use it.
Thanks for the help guys!

US T-Mobile VoLTE support?

Does the US version support US T-Mobile VoLTE without reflashing mixing US oem.sin into foreign firmware?

You'd need to be on US region firmware to use VoLTE. For example, I flashed my Xperia 1 (J9110) to J8170 and everything works, including VoLTE - except for the 2nd sim.

It's carrier depending. The Sony is cable.

Silly me. I didn't realize this isn't out yet. GSMArena indicated October release, and I assumed it was already out and came here.
I suppose we won't know if the Xperia 5 sold in the US (ie Amazon, BestBuy, Adorama, etc) will support VoLTE out of the box. XperiFirm shows:
J8210 (listed in GSMArena) - UK & Ireland
J9210 (listed in GSMArena) - Europe, UK, Russia, Taiwan, HK and China
J8270 (listed in GSMArena) - Not found in XperiFirm
SOV41 (not mentioned in GSMArena) - Japan
901SO (not mentioned in GSMArena) - Japan
I suppose it will support VoLTE, as I read in the past in another thread about how the international firmwares recently started including VoLTE for the US. I am still on the XZ1 Compact, so I don't have any personal experience.
EDIT: Sorry, the thing about US VoLTE support in international firmwares might have been from the Samsung threads. I've been researching the S10e and Xperia 5 as my next phone after my XZ1 Compact, that my brain is fried.

IT does not. Here in Denmark, Sony got zero volte or wofi, it's carrier lablet.
And they know, phones is NOT Sony's prime, no more.

Any chance that WiFi calling works as well? I'm seriously considering this device as an upgrade from the XZ1 compact. I'm probably hoping for too much here as that would have required a certification.

Unfortunately WiFi calling is not showing up for me on T-Mobile US. I can't remember the last time this was an issue. I'll call them later today to see whether the plan on whitelisting the Xperia 5 for WiFi calling.
I also can't tell if we're actually using VoLTE or not. The option is there in setting and LTE stays connected during a call, but I'm not certain whether the call is actually connecting nicer LTE.

Okay, thanks. As far as the VoLTE, I've found the LTE Discovery app works well. Just make a call and verify it's still using band 12

I just made a call and watched the app. Unfortunately I remained on Band 4 during the call. Sounds like this means the call was not using VoLTE. Very disappointing.
Just received a call and there phone app said the call was over WiFi. That setting is nowhere to be found so that's interesting.
The person on the other end did confirm a echo on speaker phone, though. Not sure how to get rid of that.

Thank you. That's an interesting find. Also, I wouldn't expect the phone to switch during a call from band 4 to band 12. The only way to see would be to find a spot where you're on band 12 and see if it switches away during a call. It should stay on the strongest signal band.

Ah, I misunderstood your point about band 12 originally, apologies. I received calls yesterday and today and the Phone app says "calling over data," so I guess that is how they're saying VoLTE. I swear the terminology shown for both VoWiFi and VoLTE was different on my OnePlus 7 Pro.
In summary, for those skipping to the end, VoWiFi and VoLTE seem to work (on T-Mobile USA) even though it's not obvious.

VoLTE is available and works
I do not think WIFI calling is enabled/allowed on this phone.
I could not find wifi calling settings to enable/disable on the phone, so i did some tests to check if it works:
1. When I call within a WIFI network and TMobile off, the calls wont go through.
2. Also, when everything is on and I am connected on WIFI but very poor TMobile connection, I do not see WIFI calling

There is indeed no option to enable this but WiFi calling does work on T-Mobile USA.

I bought the phone last week. I compared the bands and connectivity with my XZ1 Compact. It definitely has VoLTE including band 12, but unfortunately it does not have any working WiFi calling on Tmo. No option and it doesn't make calls or texts on WiFi only connections.
I will say that it does seem to have a slightly better signal strength than my XZ1 Compact had.

Bump for any updates?

I get calls in lte mode so yeah I'd say USA volte works

A little heads up though to get anything other than WiFi working I did have to go into the SIM settings and turn on mobile data as well as enable VoLTE and VoWiFi, not sure if that was related to activating it on release day or because it's the global model on T-Mobile (didn't really look into it since it was just flipping 3 settings then everything just worked).

Volte & 5G Activated on Android 12 Beta

Hello guys,
Finally the good news (at least for us in Saudi Arabia) Google has activated Volte & 5G on the latest Android 12 beta (May.2021)
But i am still waiting for the Vowifi activation
If anyone living in different countries can confirm as well
Thanks.
Update: in Android 12 beta 2 it was disabled again
What a stupid decision making

Good news bro

No change in Belgium (Orange, Proximus) with A12 Beta 1 , no VoLTE, no VoWifi

Same for Portugal(NOS) even on Beta 1 VoWiFi and VoLTE remains locked

VoLTE working here on 3 Austria too, don't have 5G enabled on my plan anymore so can't comment on that.

No luck with kuwait Stc

Anyone tested this in Hong Kong yet?

Is it still working after beta 2 update?

Anyone for uae ?

VoLTE & VoWiFi in Poland still blocked. Tested on Polkomtel and T-Mobile carriers.
It didn't work in Android 11 too...

The same for Orange BE, Proximus: VoLTE & VoWifi not working (A11, A12B2)
And we are in 2nd half of 2021..

I guess if Android 12 does not have the voiceover LTE then moving to root is the only option we all are left with. I am going for iphone anyways once it is confirmed that a basic feature of voice over LTE still does not exist after Android 12. Google pixel has been a terrible experience in advance times.

So there is a July security update which has a voice over LTE support for certain networks. Definitely not Middle East because I tried still not working I think it's just for some USA carriers

I enrolled in beta and on 2.1. Well the request still goes to deaf ears for Google.

Sorry on beta 3 but still no volte. Makes it clear that it's time to move to custom ROM and make the most of use of this phone now.

did you find any custom rom with volte working for you ?

No but I am currently up to two things.
First is that I am on the process of selling this phone on a local classified online.
Second is to check by rooting the phone.

I don't think any of the custom rom supports voiceover LTE by default. You really have to use the magisk by rooting the phone.

Pixel 5 will be totally last Google phone which I bought.
Official build of Android 12 comes this morning to my device, 5G, VoLTE, VoWIFI all these features still LOCKED!
Google is not a company which I can trust anymore.
