Iam using the Jio services on my Yu Yureka.But when I tried to call then the Call always disconnected.After having a call with customer care, I got the instructions to install the Jio4G Voice. But This App is very bad.It always force closes automatically on placing a call.By good chance call connects but Jio’s network causes issue and call drops.The App is not handy at all.It’s just a crap and not use friendly.
