How to Enable VoLTE and WiFi calls on Lumia

               Before I share step-by-step the way I enabled WiFi and LTE calls on my Lumia 950 XL, I think it is very important to say that no one but us, the disgrunted users, have the power to discipline companies. In this case, Microsoft.
Windows phones started with the promise of an open OS that the users literally own, and great hardware. After spending a lot, I feel I ended up being abused and sacrificed - Voice over LTE and Voice over WiFi are just a small part of it. It's not part of an open OS, but it is the hidden part of the OS, another monetization trick. It's not depending on the operator to enable functions the phones were marketed with, and after being sacrificed, I am literally the last person left to enable it on my phone. I was even reading somewhere that MS in India refused to do it.
                Something tells me (Windows 10 Snapdragon laptops, to be precise) that MS won't let the mobile die - it will only let current users die off. So 5 years from now, when you'll be thinking about that new, shiny Windows phone, don't forget what MS is doing to you right now; skip it for the time. And maybe this year switch to Linux, Chrome OS, Mac or at least revert to Windows 7 - just to show MS you're not taking all their shit without a fight.

                Now down to business. First thing first, VoLTE and VoWiFi need to be available (the operator offers the service and it is enabled for your number, if necessary). Then:

1. Download Interop Tools L from here; there are a number of download sources and Interop Tools versions on the internet, if it doesn't work just find the right one (2 versions worked for me);

2. Read the "Readme" file and install it; swipe left on your home screen and check out the apps list, when it is installed it will appear first as a new app;

3. Open it and and select "This Device" as provider:

4. Select the registry browser from the top left menu:

5. Navigate to HKLM\SOFTWARE\Microsoft\Cellular\MVSettings\IMSISpecific:

6. Over there, you will see a folder with a random numeric name, that's where the WiFi calling is hidden; if there are more of those folders, figure out which one is active then open it, open CellUX, then look for the keys named ShowWiFiCalling, ShowWiFiCallingPreferences and DefaultWiFiCallingPreference. Open them up and change the value inside from 0 to 1. If the keys are not there, create them manually:



7. Go back to IMSISpecific and open the "Default" folder, that is where VoLTE is. In "Default", open CellUX, look for ShowVoLTEToggle and change the value to 1:


8. Done here; exit everything and go to phone settings, network and wireless, cellular and SIM, SIM card settings and turn on LTE and WiFi calls:

Not showing up. Triple checked everything but still not showing up in SIM settings. (Digi-Ro)

Got any screenshots? Maybe we can figure it out. Mind that you'd have to trick Digi into activating it over a phone in their "approved" list.

Salut, din nefericire nu mai pot pentru că într-un final a decedat după o căzătură mai serioasă. Îmi pare rău.

Hey Friend, I need your help in working this out on JIO SIM.
I had Installed T-MOBILE ffu
Tried your Registry Trick,
Tried Filed Test, and Forced Carrier to Use LTE Bands. But In the End, Nothing Worked.

I want to know, How to Register IMS? If Operator is not Sending Settings.
JIO Operator in India, is working on Lumia but only for Data Connection. You cannot make a call.

I also Didn't saw any Wifi, VoLTE Options Enabled in my Phone. Please share your email.
