VoLTE for Xperia Z & Xperia X series.

[akshay2shah]

Hi Guys,
After many days of search and trials I have managed to enable VoLTE in Xperia Z2 & Z3 in Android 6.0.1.
But this Method should work on Newer Z & X series models(till 2018).

Only For Xperia Z & X series

Your carrier must support VoLTE service and it should not be locked to certain devices by your carrier.
This method Only works on stock roms.
Tested and working !

Try at your own risk.

Always make a backup of system and data before doing this in case anything goes wrong

Follow these steps,

1. Root Access and Recovery are mandatory.

2. Download & flash VoLTE .zip via recovery(only for Xperia Z2 & Z3).

3. Find this line in /system/build.prop [ro.build.type=user] & change it to [ro.build.type=userdebug] then restart phone.

4. Then u have to find the modem switcher.
its in system/priv-app and its called CustomizationSelector.apk

> download Quick shortcut maker from play store
> open Quick shortcut maker to make a shortcut using the app then go to customisation Selector \ modem switcher
> open Customization Selector app and select modem according to your network operator.
> if u dont find your operator just select volte_base_operator_trials_tar.
> try other ims modems if any of these wont work.
> if it wont work even after then try another stock Android rom from xperifirm flashtool.

5.. After selecting modem, phone will restart and you are good to go.

Try to switch another modem and then again switch to VoLTE modem. It works.

Now agin switch back to VoLTE based trial modem.

If it wont work then your carrier doesnt support VoLTE..

VoLTE is a Carrier dependent service. if ur carrier not supports u wont get anything other than the toggle in settings
VoLTE is one of the coolest services comes with 4G
im waiting with the toggle until my carrier launch the service Lol

It seems not to work for me too. All settings are made exactly like in the description. Modem selected and use volte option is enabled in settings too. Carrier is Telekom_de which supports volte also volte option is enabled in contract.

Best

Your carrier locked VoLTE to certain xperia model.
Cant help with that.

In your case VoLTE access is restricted from network side.
Remaining settings are correct by these method

If in your contact VoLTE enabled then do these steps again

1. Select any other modem
2. then again select VoLTE base trial modem.
