The Jio network is the one of the gReat network which emerged as a popular Network in india during 2016 and 2017.
As it was introduced as a 4G VOLTE Calling
many mobile cannot have that VOLTE Feature , the solution for these problem is JIO 4G VIOCE , which we can make 4G calls from a 3G Mobile.
These Jio 4G provides 4G calling , but not HD calling as they announced in the launch Event.
There are many Call Drops during Incoming and Outgoing Calls, even sudden stopping of these app.
Sometimes the Outgoing calls are not going , in some cases it was saying busy , even it was not busy.
Lastly , I can say These Feature is not so better feature provided by the Jio.
