[GUIDE] Enable VoLTE on Root (Stock Oos) Devices (only if your provider supports it)

Hey Guys
i found the solution to enable VoLTE on your rooted devices
1. You have Root
2. You need a Root explorer
3. Go in /system/build.prob
4. Go and search this: (Note: Default values are all-->0
change all to--> 1
#ifdef VENDOR_EDIT
persist.dbg.ims_volte_enable=1
persist.dbg.volte_avail_ovr=1
persist.dbg.vt_avail_ovr=1
persist.data.iwlan.enable=true
persist.dbg.wfc_avail_ovr=1
#endif
5. Save it and reboot
6.After reboot enable it in Settings --SIM & network
7. A Big Note: Your Carrier provider must support it......if not.......you have enabled it and nothing happens
------>You can test it if it works,by doing a call....when 4G still shows by your call,then your provider supports it
If 4G disappears.....hmmmm then not
cheers
try it out

Would be great if you could find something how to enable VoWifi for UK EE network. Or let me know where to search. VoLte works fine but Wifi calling not showing up.

EE does support WifiCalling but Oneplus need to bake it in to rom. Only VoLTE works.

Thanks a lot mate. Worked for me.

Should this just work if the carrier provider supports it or does the carrier need to support this specific phone as well?

I think I'm on the same carrier as danmaman (Vodafone in Germany). They support VoLTE in general but primarily for Samsung phones. OnePlus devices are not on their list. If I remember correctly it's the same with Wifi Calling.
I tried to activate VoLTE this way but it didn't work for me although it's available in my contract. Wifi Calling doesn't work either.

I've enabled it also this way...... But no chance
We have to wait:good:

*#*#4636#*#*

"persist.dbg.ims_volte_enable=1
persist.dbg.volte_avail_ovr=1
persist.dbg.vt_avail_ovr=1" Couldnt find these in my buildprop file. Rest of them were present and all were set to the mentioned values already.

The mentioned text is not in my build.prop. What to do ?

Add the lines to your build.prop
Under the rest of volte stuff
But if you are on stock Oos or beta the lines are there

VoLTE is working on Mate9 finally (kind of)!

My phone is MHA-AL00C00 and I want to use VoLTE in Rogers network. But the menu of volte is missing and I heard some body using C636 and enabling Volte in US T-Mobile networking. So I re-brand my phone to C636B191. But still there is no VOLTE menu available. Then I used QuickShortcutMaker to enable WIFI calling setting anyway. Then I upgraded to Andorid O(MHA-L29 8.0.0.0.360(C636)) and I found Volte menu is available and it is enabled. But the real phone call is still back to 3G and there is no VOLTE icon in status bar. So I used another SIM card with VoLTE enabled in Iphone 6+ and I found there IS VOLTE ICON in status bar. Please see the attached screenshot and I placed a call and it didn't switch to 3G so it is real VOLTE call. But unfortunately this icon is gone after a while. I guess the Mate 9 phone is not VOLTE certified device in Rogers network.

I saw that but does not do anything, still my phone is switching from 4g to 3g when I do calls, I know my sim has VoLTE activated if I used with my carrier phone works fine.

Did you call to Rogers? How they did comment this?

From Rogers forum somebody mentioned to contact level 2 support to add your IMEI to Rogers database then you should be good to use volte.

Afaik, to get working VoLTE phone must support this and mobile operator too. And they will turn support by request if they can do it.

Just chat with Rogers and this function is not enabled on my account. After enabled you have to update your emergency address and submit to Rogers. I have done this on a Rogers iPhone 6. Now I have volte icon always.

On Mate 9 ? No fallback to 3G when calling?

Yes. no fall back to 3G when calling. But it only lasts 2 hours and this VoLTE is gone again. Re-chat with Rogers agent and they said it is not working on non-Rogers phone even you are lucky to get working for a while.
Sad!

Update:
This morning I just found the VoLTE icon is shown on status bar. After place a call the call log shows it is a VoLTE call (It also indicates it is VoLTE call during the call)
It looks like Rogers remove VoLTE restrictions on non-Rogers phone.

If the IMEI on your account is VoLTE capable, then VolTE will work for non branded devices, as long as the imei doesn't change.

VoLTE or WiFi calling working on Redmi Note 7?

Using Redmi Note 7 Global version, 4G+64G, MIUI 10.3.2.0.
VoLTE
I entered *#*#86583#*#* and dialler confirms that VoLTE carrier check is disabled (test page 4636 also shows VoLTE provisioning is ON).
On different phones using same SIM, same location, I see "HD" icon confirming "HD calling", or "VoLTE" but NOT on my Note 7.
And no new android menu items about VoLTE have appeared.
So, at first glance it seems that VoLTE is not working.
HOWEVER If I make a call, the display continues to show "4G+" and data keeps streaming, so VoLTE must be working, right? or maybe not?
WiFi Calling
I entered *#*#869434#*#* and test page now confirms that WiFi calling provisioning is ON.
And yes, a new menu item appears SIM card settings, "Make calls via WiFi". (OK so far)
However when I enable WiFi and disable mobile signal with flight mode, I cannot make a call. Dialler tells me "mobile network isn't available. Connect to a wireless network to make a call".
Also if I go to an area with no mobile coverage (instead of flight mode), same error.
I believe that my carrier (Three UK) is supposed to support VoWiFi.
So is WiFi calling broken in MIUI 10.3.2.0 ?

There should be a VoLTE icon when you open the notification shade. Works well for me, even though I have the MIUI 10.3.2 EU ROM, and I had to enter the *# code in order to get it working and for the toggles to appear under SIM settings

Thanks for the reply. Hmm yes, that's what I expected, but icon is definitely not there.
It's especially strange since I have definitely had VoLTE with the same SIM successfully on different devices.
What do you make of my phone staying on 4G during a call, does that suggest VoLTE is actually working?

If your 4G icon doesn't change into 3G (H) while in a call, I'd say VoLTE is working for you. It might be that there is something missing in the VoLTE handshake between the carrier and the phone, not passing all the checks and resulting in the phone not detecting "full VoLTE connectivity" and not showing the icon. If a call to another phone also using VoLTE starts ringing really quickly, if the sound quality is really good and your phone shows that it's connected to a 4G network, that should be it. HD or VoLTE icon or not, the functionality is there.
You said the same SIM has had VoLTE on other phones, so the carrier side should be OK. Although I suppose there might be a device whitelist on the carrier side – there sure was one when VoLTE was first introduced, as not all VoLTE-enabled devices were eligible for the service. At least that's how it was in my neck of the woods. So if all else fails, you might want to verify that with your carrier.
On the Redmi Note 7 though, as I said, it required that I enter the *# code for VoLTE. After that, the VoLTE toggle appeared under SIM and wireless settings. I can't tell if the toggle was in the "off" position when it appeared, but I'm quite sure that right after seeing or switching the toggle, I checked the status bar for a new icon, and there it was. No restart was required. You could try re-entering the code and seeing if the toggle appears (as in the screenshot).
Your profile states that you're in a brexiting location, which makes me think – do you have the Global ROM or the EU ROM? My MIUI version says PFGEUXM and VoLTE has been known to be disabled or not working in certain editions of MIUI.

I enabled VoLTE toggle and also Calling over Wi-fi but when I try to make a call it won't work saying I need to establish a cellular network connection.
Is there a way to make it work?

Your mobile carrier needs to have VoLTE enabled on your account to make it fully work

use *#*#86583#*#* as ON/OFF switch !
===================================
use it once = it turn VoLTE "ON"
use it second time = make VoLTE "OFF".
For "Use Wi-Fi to make and receive calls" type *#*#869434#*#* once.
for turning "OFF" use the same code (*#*#869434#*#*) second time.
Easy-peasy !
(btw. I'm on MIUI Global 10.3.6, no root, original ROM)

@kljoki
I have it exactly like this. Because when it is deactivated you can't see toggle options in settings.
I am on MIUI Global 10.3.10 Stable PFGMIXM
So what am I doing wrong.
My provider O2 Telefonica is supporting Volte?

Sorry I'm on Xiaomi Note 7 .
( I think there is no help from my side.)

Has anyone got WiFi Calling to actually work?
If so which carrier are you using?
Have the feature activated but like the other poster, I cannot make calls over WiFi (T-Mobile) made wonder if there's any additional steps needed to activate the service

Could someone already test if VoWIFI is working with the Miui11 Beta versions, plz?

Derpfast-Rom is unfortunately not updated any more - had VoWifi working...

Have a feeling they disabled it on purpose to not canabalize their higher end model sales.
It's been the same story since MIUI 10.3.5

I'm using latest crdroid with no success on this subject. BUT i use TIM Brazil carrier so i believe this is not a rom related issue, but a device+carrier issue.

VoLTE has worked great for me from the start. Had to enter the VoLTE code in the dialer to get the switch in the options to appear though.
VoWIFI - what's your motivation to use that? I have good coverage where I live and I'd rather have a real cell phone call than for it to go through my home or office wifi without QoS set up to prioritize voice calls.

is it right that vowifi doesnt work with miui 11.0.5 on my redmi note 7? VoLTE works?

Unfortunately I'm just having wifi during work inside my hospital.
Means I'm not getting any calls on my mobile as a backup. Quite disappointing. :/
Update:
By a HowTo in the german android-Forum I made it possible to activate VoWifi on my Redmi Note 7 , without rooting or bootloader unlocking.
Had to delete row_commercial profile and activated Commercial MTS for Telefonica in Germany.
Works perfectly -. @Antaril

I'm curious how they determined Row Commericial must be deleted.

VoLTE / WiFi Calling with Nokia X6 / 6.1 Plus TA-1099

Hi,
after upgrading to Pie I experienced call drops and poor coverage.
I then investigated and found out VolLTE, which should be supported, is not enabled in my phone. I also understand that WiFi Calling is also supported by this phone, but I cannot find out where/how to enable it.
The phone is not rooted and I use two sim cards: Vodafone and EE.
I dialled *#*#4636#*#* and "VoLTE provisioned" is disabled, "Video Calling provisioned" is disabled, "Wi-Fi calling provisioned" is disabled and "EAB/Presence Provisioned" is disabled. Is that normal?
Please let me know
Thank you!

Does your carrier support Volte and VoWifi patches for this device?

Hi, yes they should do. I

VoWIFI Calling has been enabled in my device (Jio).

I am still not able to see Vowifi calling option in my handset...I have airtel sim card

Airtel supports wifi calling on nokia 6.1 plus. I am using it. Try to enable it with jio sim. Then use airtel sim. It worked for many users. u ll see the option to enable wifi calling then.

I have sold the phone, it just did not work properly
I then bought a Xiaomi MI 9 SE which is MUCH better in every way
