I have a phone J7 prime G-610F, which was i bought from UAE 🇦🇪. And now i am using that phone in India with JIO network, but unfortunately the sim cad doesn't allowing call without jiocall app. And for all the time the data keeping on it is like something loosing without reason. So is there any way or idea to get this problem solved. And can it be possible to get VoLTE network mode in J7 prime phone?
