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.

~ Samsung Galaxy Tab S 10.5 LTE ~

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
VoLTE on Xperia Z3C working on Reliance Jio India

The following instructions given for Xperia Z3 and Z2 works fine on Z3 compact too. I have been able to enable VoLTE and use the phone with Reliance Jio 4G VolTE network in India.

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.
First I do not have an S6 yet but am researching before Purchase and main concern
is Battery Life ....but this is a General Question.
On Metro PCS/ Tmobile we already have VoLTE on all Devices which have 4G LTE
Radios which are Carrier Branded Devices.
Metro PCS was one of the first so back in 2012 my little LG Motion 4G had simultaneous
Voice and Data on LTE Band .
My current Factory Unlocked Alpha 850M is CAPABLE of VoLTE but lacks the specific
TMobile Software for VoLTE on this Network so as soon I make a call the LTE
drops down to 3G or H H+ to make the call then returns to LTE after the call.
All unlocked Devices do this .
HOWEVER: the Galaxy S6 has a VoLTE setting in the Menu - on a MetroPCS/Tmobile
version on Tmobile/Metro you already have this function so:
1) What does VoLTE switch do on S6 Tmobile version - you stay on LTE During calls
either way - right ? VoLTE ON or OFF.
2) Since there IS a VoLTE switch will this be the FIRST Device that enables VoLTE even
as a Factory Unlocked version running on Tmobile/ Metro ?
Meaning - is this the beginning of VoLTE as a Universal Android Feature across many
Carriers not requiring specific Carrier Software for a Specific Network to enable
VoLTE on multiple Carriers ?
Thanks for your patience - I am not a Dev and have learned much here.

I don't believe this is the case YET. Android AOSP has VoLTE built into it as of OS version 5.1 (as seen with the Nexus 6). Prior to this the VoLTE was handled by carrier software on carrier devices. I do not know if another carriers S6 will use VoLTE on T-Mobile without being flashed with T-Mobile software first.
That being said going forward we should see a VoLTE "Universal Android Feature" that is compatible with any device/enabled carrier but not until 5.1+
You're confusing a few different things
- Simultaneous voice + data was always available on GSM networks, it uses the regular GSM radio to place the call and then data is separate. This is not VoLTE.
- CDMA carriers (Verizon, Sprint, old Metro PCS) had trouble with voice + data, CDMA didn't allow it to work. When LTE was introduced, it gave them the ability to connect voice through CDMA and data via LTE, so that's how they were able to do simultaneous voice + data. This is also not VoLTE.
- VoLTE is sending the call over the data LTE network. This is also different to WiFi calling. So instead of your phone call being transmitted as a voice call, it's turned into data, and sent through T-Mobile (or whatever carrier's network) as data. You can have a VoLTE call and use data as well, it's the equivalent of having 2 data apps running at the same time.
- There have been a few VoLTE enabled phones already, I believe the Note 4 and Z3 both have VoLTE. There are probably others, I just don't know off the top of my head.
We have Had VoLTE Phones on Metro PCS since August 2012
Again-we have had VoLTE Phones since 2012 on Metro PCS :
http://www.pcmag.com/article2/0,2817,2408750,00.asp
I had one of the first Models called LG Motion 4G- the Call
AND the Internet while on the Call were all over LTE.
Metro PCS was one of the first to offer this and most of their
LTE ( if not ALL) have had this feature since AND TMobile has
adopted this Feature to most of their phones.
But I don't want to get bogged down in that Question.
The Question is - On Metro PCS /Tmobile you ONLY Get VoLTE on a Metro branded Phone-
AT&T issued an OTA UPDATE for their first VoLTE Phone which
was Galaxy S4 Mini .
There is No Factory Unlocked Phone which can get VoLTE on Metro PCS ( but their Branded 4G LTE phones do have VoLTE)
BUT - since VoLTE is a Function in the Galaxy S6 and is somewhat supported by Android Lollipop -
Will Factory Unlocked Galaxy S6 be the First Phone which will
Stay on 4G LTE during a call even when you get on the Internet?
Other Phones which are NOT Carrier Branded drop down to 3G during calls and thus have slower data speeds during calls etc.
The new Galaxy S6 Active will probably have an SD Card and much larger Battery -probably exclusive to AT&T
BUT Factory Unlocked Models will become available -
1)IF I get a Factory Unlocked S6 Active and turn on VoLTE Feature-will the Device stay on 4G LTE during calls with Data - VoLTE ?
2) Metro PCS LTE phones and Tmobile LTE Phones already have VoLTE so again what is the difference on S6 if you turn VoLTE on or off in the Menu ?
3) My Factory Unlocked Galaxy Alpha 850M does not have the VoLTE software for Metro/ Tmobile so I am on LTE but as soon as I make a call I drop to 3G ( it shows on the screen) with slower data and sometimes data interruption.
Will S6 do the same thing if an Unlocked Phone or be the first Factory Unlocked Phone with VoLTE across multiple Carriers ?

I have a MetroPCS Galaxy S6 Unlocked and VoLTE Works Fine and also I have the T-mobile firmware on it I'm not sure if that would change anything but I was just saying for me it works perfect
Sent from my SM-G920T using XDA Free mobile app
So I'm using the at&t Samsung s6 edge in India with a jio SIM and I have the 6.0.1 updated version
Firstly can I get updates on it from at&t like OTA?
Secondly I have a volte issue
So I have the options enabled for enhanced LTE services and on most forums that is enough for volte apparently but I'm not getting a volte signal
Just 4g LTE
Any idea how to enable the volte?
If rooting is required I'm up for that too but would prefer without rooting if possible
Did your issue was fixed? IM suffering with same issue,..LEt me know..
