Hello,
I am not sure how VoLTE works with the x727 and stock rom. I am from Mexico and my carrier is AT&T, they offer a "HD Voice" feature (https://www.att.com.mx/servicios/voz-hd.html), they say it only works while having 4g signal, wich I have almost all the time, and the call must be between 2 at&t phones. My problem is that every time I make a calthe signal drops to 3g (the icon changes to H or H+), is this normal? Could it be a problem with my phone or the AT&T network?
Thank you all
You can have HD voice over HSPA+. VoLTE is even higher voice quality. I'm not sure if Movistar has VoLTE capability but likely they have HD voice over their HSPA network.

I have SM-N910U model of the note 4 and would like to know how I can enable voLTE. I know my phone supports it, but I can't find it anywhere in the settings nor is it active. My carrier has voLTE, but the phone data drops to 2g when I make calls. I would like to know a way to enable voLTE, so the data stays at 4g while on the call.
Or is there a way to add volte to international roms seems like it is only for carrier branded phones
I have the same problem with Galaxy Alpha on the Metro/ Tmobile Network.
LTE drops to 3 G on calls and often kills Data
during and even a minute or so after the call.
Not good for multitasking- this is a Factory Unlocked Alpha NOT a native Tmo / Metro phone .
The 4G LTE Tmo/ Metro Phones always have simultaneous voice and data so you can be on Web while on a call.
I think some have VoLTE and some have dual band simultaneously in the firmware specifically for Tmo.

Yes you are correct. VoLTE service can be enabled only with layer 1 modified kernel/drivers. The hardware itself definitely supports it, but firmware doesn't. Main reason the Samsung decided to disable this feature is because not all carriers in the world use voLTE service and enabling the service on the user end may trigger unstable and disconnection during call. I have contacted Samsung by Twitter and have yet to receive a response if they are going to enable this feature or not. Will let you know if I hear anything back from them!
Thanks. I wonder if some Dev here can do it for $ 100 .
Really like the size, speed and great Audio quality of Alpha and was going to get the larger Battery but I often can not get back on Internet for a few minutes after a call-
while the Phone says 3G (?) then it goes back to LTE and back to Internet...frustrating .
Am used to Metro PCS VoLTE since 2012 and had not considered this problem with a Factory Unlocked non Carrier Device.
No one reminded me there would be no VoLTE and sometimes no voice and Data simultaneously...
So DEVs figure it out for me and I will have a Tech here do the Install/ Download.
Alternative will be a too big branded S6 either Tmo or Metro which will have a better Camera, even slightly better than Note 4 but I love the small form factor of Alpha- this is Alpha 850 M.
Don't think Samsung will help although there is rumored to be VoLTE with Lollipop so there's a possibility.
Will Lollipop VoLTE perform like a Branded Metro PCS with LTE remaining on Display during calls and simultaneous Internet ?
Anyone have a Beta Lollipop for Alpha that achieves this ?
Thanks.
As you can see, I have two radios, one LTE and one 1x, same as on my last few phones. When I make a call though, the LTE is not available for data services, and 1x doesn't even show as a data option when voice is active. I cannot activate advanced calling because I'm not technically with Verizon. Is the problem that the calls are defaulting to the LTE radio? I've tried disabling volte in the network settings and it doesn't do anything.
Suggestions?
One of my friends came from overseas a few months ago with VoLTE working on Tmobile US. At least I thought it was.
I did not think much of it at the time, but now that I have my own Z5, and can't get it to work, I'm curious.
Is there any special APN settings needed for VoLTE on TmoUS?
WHen i received my Z5, I noticed there was not any option for VoLTE. I went ahead and flashed the a singapore rom and it is here now but still cannot get it to work. I will try different settings and update.
I am also going to go through a few more roms to see if they work out of the box with it.
WIll it not ever work unlesss TmoUS certifies this device specifically? I don't think that is the case.
It's carrrier dependant
VoLTE uses the SIP protocol for communication. Aside of the implementation of the handling of such calls you would need the necessary data for registering at the server including the server's address, username and password.
I bought my international version from Amazon and turns out it is a Taiwanese version.
I can turn volte on or off but I can't tell it is working or not cause I don't know how to test it.
Testing it is pretty straightforward. Make sure you're on a 4G (LTE) network and place a phone call. Watch to see if you're signal changes to something other than where it started.
My experience is that I have 4G (LTE) in fewer places than 3G, as 4G seems to be less awesome at penetrating thick buildings. So, I don't see what the advantage/concern of VoLTE working or not is. But, I'm happy to learn.

When I make a call, the icon switch from 4G into 3G and H+ (back and forth between the two).
Does it mean no VoLte?

I have the same question too.
That's my understanding of the problem. With my AT&T iPhone, it stays reading LTE when I place calls.
If you see switching from LTE to another network upon dialing or receiving a call and going back to LTE once hung up it's a very strong indication that VoLTE does not work.

THat is correct. My phone switches from 4G to H+ when on a phone call...
After many hours with t-mobile, and also at work, i was informed that t-mobiles VoLTE is proprietary and only tmoUS branded devices are usually the ones to get VoLTE to work with them.
Maybe in the future that will change, they said. oh well.
Until now every provider's solution is proprietary as the 3gpp standard is not finalized yet. So we need to be patient...
Hii,
I looked around and couldn't find any similar thread.
My network provider is Aircel in Chennai, India. MotoG4 Plus. Android 6.0.1
Most of the time my phone displays 'H' next to the network signal bar. Mobile internet works perfectly fine. As soon I make a call, the 'H' changes to 'G' and voice quality is pretty bad. Isn't it suppose to be 3G (H) for the calls too? Sometimes an '!' mark also appears at the end of the mobile signal. Not sure how to fix this. Voice quality is bad.
Any help?
Networks in India, aside from the major ones (Airtel, BSNL, Vodafone etc), usually have deals with the major ones for the 3g spectrum. Which means, the 3g bandwidth you are using in your telecom circle is of an another network's... However, the 2g spectrum is still your operator's spectrum & not a different one. Therefore, if you call, the operator forcefully switches your network from 3g to 2g. If you want calling in 3g, use a network that has bought the spectrum in your circle (usually Airtel, BSNL & Vodafone).
A similar thing exists with "VoLTE". LTE in India right now (with the exception of Jio) falls back onto 3g/2g for calling, while using 4g fr data. Whereas, VoLTE uses LTE for calling too.
The exclamation mark indicates that the phone can't connect to Google servers to verify whether your Internet is active.

Thanks a lot Aditya for your reply. :good::good::good:
So I use my sim on roaming and I have been facing this problem that my calls only work when I set mobile network to WCDMA or lower which hence reduces my data speed coz it's 3g. What to do?
4G (LTE) services is a data-only service, and does not support voice (unless it is voice converted to 4G data or VoLTE), hence whenever you're dialling or receiving a call network drops from 4G to 3G. Happens to me all the time on roaming, sometimes even on home network with poor VoLTE connectivity. Nothing to worry about.
