It is good network but call is dropping very much voice problem
you can use other llike as idea airtel and other
I like its free calling plan and dislike about speed 4G speed minimum 10 mbps but here is 1mbps maximum
its good quality buy buy without any cost
here is very much fast and long battery life handset is available in market but problem in Jio sim it is run only in 4g handset and you have too VoLTE for calling so when you buy a handset then mind it to be in your handset otherwise you can’t enjoy full feature of this product.
