Jio4gvoice is very good app of realince jio which is used for messageing , calling ( audio, video) .
There is call droping problems are comeing in realince jio but jio4gvoice help us to call with one dial to realince jio number as well as other number too.
But this is working only when your mobile data is on.
Their are so many of complaints against realince jio for call droping .
So , I am shareing my experiance with jio and redmi mi4i .
This app is working .
Jio4gvoice is also good for video calling to 4g device to 4g device
Thanks
