J7 Prime Calling Problem

[snipranshul]

I have J7 prime and I use only one sim JIO. After Updating it in Nougat version it can't make call. I have to download Jio4gvoice for calling although J7 Prime is Volte. What is the problem ?

Try enabling voLTE calls under MOBILE NETWORKS

I don't have Volte Call option in mobile networks...

It should be there if your android version is 7.0.
This is how it looks like

Although my android version is 7.0 (You can see) but there is no option for turning on volte calls....
