I personaly used jio 4g voice and want to told that it’s not good.
though it have a new generation calling facility but call can not connect most of time or if connect then it have many bufferings.
so I personaly realised that jio is not good.
it’s network signal also not good.
and the layout & design of the can much batter.
jio 4g voice the online calling system this concept is good but service is not good.
if you want to call someone then you have to on data connection and then wait until this application go online.
after going online then you call someone.
so this a problems for senior citizens.
