[Q] VoLTE?

Hi all,
I have a Z3 Compact and just want to confirm it is capable of VoLTE? I read somewhere it is but cannot find much official information. If somebody could make it clear I would appreciate it.
Regards

http://www.xperiablog.net/specifications/2014-xperias/xperia-z3-compact/ it does

Good, is this supported on a hardware level or via a firmware update. When EE and Three launch their VoLTE service will the phone just support it without additional updates?
Regards,

I do have Z3 Compact with T-Mobile, but there is no VoLTE option
Using Xperia Z3 Compact on T-Mobile USA and trying to find which country will have firmware that has VoLTE option. My phone is from EU/Italy and I have Android 5.0.2 installed, but don't see any option to enable VoLTE. Any one has this option?

Check in /system/etc/customization/modem and you'll see that every firmware contains all modems.
Also, under Software Info in the Service menu it will show which modem is currently loaded.

I just went to Service menu and checked out Software info. It does list GSM/WCDMA/LTE, but how to find out if this phone will have Voice Over LTE? I used T-Mobile branded Z3 for a week and it had an option in "call settings" to put a check mark next to "Enable VoLTE". Once enabled, the signal stayed on LTE network instead of switching to 4G when making a call. The call itself connected faster and the quality was good. Right now even when I am on LTE and make a call, the signal drops down to 4G for the duration of the call, then after that goes back to LTE signal. I know Xperia Z3 phones support this feature on a hardware level, even white pages for Z3 Compact mentions VoLTE, but I can't find the setting. I read somewhere in UK, 2 carriers like EE, going to enable VoLTE in the near future, so I thought one of the UK firmware would have that enabled by then.

As far as I know VoLTE is carrier dependent. Actually maybe few around the world test this service even tough many phones are hardware ready for new standard. You can see the list here: http://en.wikipedia.org/wiki/VoLTE. Please let us know if you find out more.

The build for T-Mobile Germany has this option integrated.
~ Sony Xperia Z3 Compact ~
~ Samsung Galaxy Tab S 10.5 LTE ~
~ Huawei Ascend P6 ~
~ Acer Iconia A510 - CM12.1~

Interesting... Do you know if device from T-Mobile Germany is locked or unlocked? My device is unlocked and if I flash it with T-Mobile DE, would it lock the device?
I found this firmware on Xperifirm and it seems to be latest available. Is this the one you mentioned?
Device: Xperia Z3 Compact (D5803)
CDA: 1289-4143
Market: Germany
Operator: Telekom.de DE
Network: GLOBAL-LTE
Release: 23.2.A.0.278 / R11C
Size: 1.49 GB

Yes this is the firmware, I use.
You can remove most of the bloatware.
My device is locked.
I really don't now, if flashing this firmware will lock your device. I never used Flashtool.

I am trying to find out on another thread if flashing locked firmware on unlocked device, what happens. So I will know soon, but I heard that flashing firmware doesn't change SIM Lock, so if it was locked, it will still be locked and vise versa.
I have 2 questions:
1) Is the VoLTE option is in settings>call options and then it says "Enable VoLTE"?
2) Do you also have Wifi Calling?
Thanks

Sorry, I don't have SIM lock. I thought you meant a locked Bootloader.
Flashing another firmware doesn't effect SIM lock.
Yes, it is in settings - > calls
No Wifi calls.
BTW:
O2 Germany will activate VoLTE in the next days on all devices, which support this feature.
So I think, O2 Germany firmware should also have this option in settings - > calls

Thanks for the info! I have flashed my phone with few different firmware: UK, Generic DE and yours Telekom DE. I don't have that option. I checked everywhere... Looks like I may also need to have Telekom sim card and adjust some carrier settings. If nothing helps, I will flash back to original firmware and wait for some other solution.

Maybe this option is hidden, and only shown if your provider supports VoLTE.
Two of my colleagues have also a Z3c. One with Generic DE and O2 Germany SIM card and one with UK firmware, I don't now his provider.
I'll have a look into their settings.

T-Mobile USA has VoLTE and Wi-Fi Calling features. All the phones that are T-Moible branded have these features. That is why I was trying to flash your firmware Looks like not only firmware and hardware support plays a role, but also something that carrier has to enable support for Xperia Z3 Compact. My carrier has Xperia Z3 regular and it has VoLTE and Wi-Fi Calling, but the phone is too big for me.

Hi I found the post today about features that Android 5.1 will bring and looks like VoLTE might be one of them. http://www.geek.com/android/heres-what-changed-in-android-5-1-lollipop-1617837/

So can you tell me if this firm worked for z3c?
If so what's the link to download it with installation instructions

Hey. Did u unlock your bootloader. But how did u root. Please tell me the process u did. I am on 6.0.1 firmware

VoLTE on Z3C
I have Z3 Compact 6.0.1 (D5833 - India).
I have unlocked my bootloader, rooted, flashed Starhub 6.0.1 and have enabled VoLTE on my Z3 Compact.
Able to make and receive calls with the Reliance Jio sim.

VoLTE Support

Does this phone EVA-L09 support voice over LTE? I can't get it working and I can't find any settings for this? Every time I call someone the call gets routed through 3G and sometimes even 2G. I would like to have the supreme in call voice quality back, that I had on my OnePlus One.

No, but I think that my carrier is up to certifying the phone to the network so I'll have VoLTE soon.

With the Nougat B360 Update I can enable VoLTE via settings. I'm on Telekom DE.

@africa89
No, I just did the Update and the Settings were there. Maybe VoLTE is something your provider has to enable? AFAIK the older contracts of T-Mobile didn't have VoLTE enabled, it had to be activated by the provider support helpline...

Can anyone or in any rom Volte will be activated ??

Go to your network provider shop and ask them if they have enabled it for you .. You MAY BE need different packs .. or deals from Your OP
I just put EE-uk into Mate 9 (right) and it automatically showed option wifi-calling.. If I would remove EE sim it will goes away..
And there is calling over WiFi or 4G.. It is little bit weird that 4g network is packed in to wifi calling.. Which clearly is not
It should be separated option.. But it is just the way how wronlgy EE operator did it..
On the left it is P9 but I did it force way as it was patch applied because I was rebranding P9 to China and flashing oreo so patched VoLTE option.. It wasn't there previously in android 7

Wifi Calling

Hello All!
Im new at this topic, because some weeks ago, i bought a z3 play phone, i coming from a moto maxx (quark) from motorola..
I want to know how i can enable vowifi/ wifi calling for use with my z3 play, because i cant found this option on the menu, when i search it, only appears the option for "enhanced 4G mode" that include Volte calls (volte works well and wifi calling works in other phones but with my z3 play no) but i want use with wifi calling, currently im using android pie, and the model is, XT1929-6, opencl channel.
can some one help me with this?, could be useful change to other stock rom?, opencl -> retla, or retail?, the current software compilation is: PPWS29.131-27-1-11
Thanks you a lot!

I have bought this phone on carrier called claro, if I install lineage or resurrection remix could be use wifi calling or volte ?

I mean what carrier are you using it on? If you using Claro Argentina then perhaps it should work. If you're trying to use it on another ClaroNetwork I'm not sure. you need to specify what network and what country that you're going to use it on as well as what network and what country the model is. For Verizon they only support Wi-Fi calling on models they sell. The same with AT&T.

My carrier is claro chile, in my case. When I use other simcard(with volte is working on other phone) in this phone. Not works, but if I use the. Claro simcard only appears volte.
I want to know if flash the resurrection remix. For example, could be possible use both services. But I’m not sure if this work or not. Up today I don’t know for someone that are using resurrection that says if volte / vowifi works in this custom rom.

ok i just quickly checked several utube videos and i see “global” device have VoLtE icon.
So I guess with global rom it will be fix bro

I have the Chinese variant of the Mi 11 Ultra and by default, I was unable to see the options to enable VoLTE and VoWifi.
If you enter the following codes into the dialer, it should work:
VoLTE *#*#86583#*#*
VoWiFi/WLAN *#*#869434#*#*
These codes disable/enable carrier compatibility check. Then go into Sim Card and enable VoLTE or VoWifi.
Since VoLTE is required for RCS in Google Messages to work, enabling this also allowed for 'Chat Features' to be ready on my phone.
Quick note: I am in Canada on the Virgin Mobile Canada network.

I did this but the icons never came up.
I'm in australia using telstra and got the china version

Did you get the pop-up stating "carrier check disabled"?
Go to settings>sim card & mobile networks>select sim 1>you should see the options here.

Have you rebooted?
Have you made a call to see if you stay on 4G?

Even I face same problem I'm using boost sim ,I've enquares the Carrier but they said they support vote , I'm not able to get volte working in my device

Same issue. Got the Chinese variant of the Mi 11 Ultra, running 12.5.12 EU ROM and I'm on Boost (Australia). I've done all the dialler codes and still no VoLTE icon. Calls drop to 3G.

i've done a deep search regarding VOLTE on Telstra in Australia as I am facing this issue too, and I found out the following result:
This issue happened because Telstra did not share its network settings with a few companies, Xiaomi, Oneplus, and others.
On a different thread on Oneplus section, there is a way to fix it that requires root, so we add Telstra settings manually, but whenever a tiny update shows up, then we'll need to repeat it. a restart won't affect it, just an update because it replaces modified network settings file with original one.
so to summarise it, unless a software update with the new settings come up, then it won't work.
And btw, the VOLTE is working on MIUI first version of 12, and MIUI 11. but after the update, settings lost. and this is not an issue with MI 11 ultra, it is with all xiaomi and oneplus devices and a few others.
Do not waste your time on it, and just cope with what we got and be patient.

Thanks for this information, sincerely appreciated. My only concern is Telstra turning off their 3G network by June 2024. Let's hope the issue is solved before then. Fortunately my call quality is completely fine without VoLTE at the moment as reception is good. I'm sure other providers will start turning off 3G too. A very odd issue and I'm really surprised it hasn't been fixed.

Did any one manage to find a solution ?

Any solution yet to make volte and vowifi work on Telstra and boost Australia? Thanks
