I have been struggling with getting a definitive answer to the question if VoLTE is possible on the H4213.
I am led to believe VoLTE is a software ability that does leverage on some hardware requirement.
After not finding the .."enable VoLTE switch" in settings on the Stock Rom but getting info from SONY that the H4213 is a VoLTE capable device, I flashed LineageOS 19.1 plus some Gapps to the Sony.
All good! Now there is a VoLTE slider in settings but still unable to get VoLTE connection. The sim is supposed to be 4G/LTE only.
When I run Network Cell Info (Device+sim) and #4636# Sim shows as ready and Network Type as LTE and in service, VoLTE ,Video calling and WiFi calling provisioned .... but Device Telephony shows Phone Type as GSM and VoLTE capable - No. Same for WiFi Call avail - No and Video Call - NO.
I have been thinking of running VoLTE-fix to see if this fixes anything but that would be of no use if the device HW is not VoLTE capable.
Anybody out there that can say with certainty that the device is VoLTE capable.
I have a suspicion that the sim may be the issue here, as I am also struggling to connect to Mobile data on the sim and the APN information looks dodgy.
This is with RainOne in South Africa, and the surprising thing is that if the number of that sim is called I immediately receive an SMS that I had received a call . SMS and Whatsapp works.
Any light on this issue will be appreciated. Ideas, thoughts anything !
Thanks

Just got off a multi-hour chat with T-Mobile tech team in US: they confirmed that they can't make WiFi Calling work on my Xiaomi Mi A1 (Global). Regular calling (Band 4) works fine.
Quote from out chat:
I have reached out to the highest level of Specialized Tech Care, and worked with them on the provisioning issues. With the Xiaomi MI A1 being a non-T-Mobile non US based phone, the option may show as available, but the device itself will not actually operate on, or use the wi-fi calling options. We can absolutely help you get into a device that supports the feature, but there is not a way to activate it on that device.
The provisioning failure is on both sides, we cannot activate the service, nor force an override to update the IMS.
The plan is setup and good to use it, but the systems are giving us an error saying that the feature is unsopported.

Symptoms and details:
Phone is a Global version with Oreo 8.0.0 and the latest security patch (Feb 1, 2018), not rooted, fully stock.
I tried enabling WiFi Calling in the Phone dialer app to no avail (Hamburger menu → Settings → Calling Accounts → T-Mobile → Wi-Fi Calling)
T-Mobile tried re-provisioning the phone. Their system was sending a special sms to enable WiFi Calling. It was understood by the phone, so I was seeing it as a regular text message:
FREE T-MOBILE SUPPORT MSG. Q's? See <REDACTED LINK TO TMOBILE SUPPORT SITE> WQGxYT92fBTCECnvS4QOiu7gzm4NPHiWMYoeXEs5riY=:WFCn|414b7f5b

Debug menu (*#*#INFO#*#* in the dialer) is still showing IMS Service Status → IMS Registration: Not Registered.
It sucks that voLTE doesn't work on T-Mobile US as well. It's what I expected when I got the phone anyways, so I can't complain too much.
yup sucks. regular calls is alright but to make up no VoLTE or wifi calling I just use google duo calls to my friends and it sounds excellent. only downside is I can only use it with people who only have duo installed.
VoLTE works great with this device.

It's so weird that my mobile company supports VoWifi and VoLTE but the phone doesn't seem to understand that. No option to enable and when i force enable it via shortcutMaker it disables itself. I double check that it's enabled by calling the company and they say that if my smartphone supports it, it sould be enabled by now...
Volte works fine here in my country
VoWiFI doesnt work in Greece, too.
How to enable VoLTE on the korean U+? I've checked with my carrier and they confirmed that VoLTE service is active on my SIM. However I can't find any option to enable VoLTE in phone settings. I've only seen a VoLTE call quality option in phone settings - not sure if this means that it's already active. The status bag logo also shows just LTE when mobile data is enabled - no indication of VoLTE.
If you have mobile data showing LTE and it does not change to 3G (or something else) when you make or receive a call, then you are on VoLTE. That is my general understanding of it.

Ah ok. It seems you are not on VoLTE then. Sorry, I don't know how to activate it though.
i have the sprint version but am currently on tmobile network which (was switching me to 3g) during voice call or txt msg.
now that tmobile has been taking down 3g (and they are working on a tower in my area) i do not even see 3g symbol in notifications anymore. i can complete the call and there is no lte symbol or 3g symbol but call completes but can not use data still.
when i hang up i see lte and can use data (browse the web)
the funny thing is before i went to tmobile i had metro pcs in this area which uses tmobile network and i never had a volte problem so you know this is software and they just want us to buy more phones.
this exact phone worked on metropcs with volte no problem.
someone know if exists firmwares that support 4G/LTE VoLTE? My provider has planned to switchoff 2G and 3G networks in some months... so i need VoLTE to make calls over 4G. For others mobile users i can use telegram or whatsapp calls but to call fix numbers of call centers and so i need a working VoLTE. Suggestions? Settings for VoLTE are from providers or i can insert it by hand into phone settings?
I have the european variant LM-V500EM of LG V50 which I was under the impression had a wifi calling / vowifi option. I've used the quickshortcut maker app and can see the option is there in the backend of the settings com.android.settings.Settings$Wifi CallingSettingsActivity. I can even open it and toggle it to on but it doesn't appear to do anything and still won't show in the regular call settings.
I've spoken to a number of UK networks who say it should work and spoken to LG directly who say wifi calling is unavailable for this variant/model and only the EE variant has WIFI calling. It's pretty frustrating that a function which the phone clearly is capable of is unusable.
Has anyone got any workarounds for this as I'm tearing my hair out here and don't want to have to sell the phone as apart from this it's great.
Thanks
I've been in engineering mode *#546368#*500# and SVC Menu / VoWIFI / W-Fi Toggle to ON but wifi calling still doesn't appear in the main settings.
Can this be enabled OTA by the right network carrier eg. EE , 3 etc ?
I've got the same phone, same problem.
Running Android 11, Smarty network

Hi,
What is EE variant? I never seen it before and I can't find it in net.
I know only those variants:
V450PM
V450VM
V500EM
V500N
Has anyone else had a problem using the internet while on a phone call? I just switched from the s22 ultra which had no problem in this department.
Is there anyone else experiencing this problem Or is this normal for the pixel?
Do you try to active VoLTE ?
For that you need VoLTE activated. And it is not supported in every country. In order to enable it you need to root your device. I am still searching for fully tested and functional mod for P7P.
Pixel is weird compared to what I was used to from Oneplus. Having 2 Sims in where the physical Sim is for calls and Sms and the eSim for data. When on a call (on phys. Sim) I don't have a data connection on the eSim anymore. When I check "use data during calls" on the physical Sim, as soon as I'm in a call the data card changes from eSim to physical Sim and Internet is available. As soon as I hang up, data connection is transferred back to eSim.
Unfortunately the check box for " use data during calls" is not available for the eSim, also both are provisioned as VOLTE.... Never had such problem with OnePlus, there data stayed on 2nd Sim when I was on a call on first one....

It should still work with UMTS/HSPA if your network has this "3g" network type available, but relatively slow.
You need to upgrade from dial-up to talk on the phone and to have Internet access at the same time.
Big sarcasm here is anyone didn't notice, haha =)
