How to enable VoLTE?

[yigitanil]

Hello guys,

I have been searching about enabling VoLTE for 2 weeks. Followed several guides on this page, but no luck. My phone now has Central Europe firmware from Xperifirm. Tried German, Indian fws with Xperia XZ2 OEM files, in neither situation I was not able to activate "enable volte" switch in hidden settings menu.

I live in Turkey, my operator supports VoLTE. I activated my sim card's VoLTE with different phone. (If I put my sim card to another phone, Volte works...) I need some help with enabling VoLTE on my XZ2 Compact

Thanks a lot

Hello,

Can you share OEM*.sin files whatever you have downloaded?
Because I tried a number of times but Xperifirm got stuck
