It was Idea to BSNL and JIO to same BSNL no. Airtel in Pune is just as worst as it is elsewhere.No idea
Must be different for you in Pune, but here airtel sucks big time. Even on full coverage, users used to go hello hello hello. at one point of time, Connected calls would drop exactly at 1 Min 13 sec. So for me calls were pathetic on 2G. If they are good for you on 2 or 3 bars then good for you!! When the user on the other end said you sounded like a old radio station, was he on Jio too? because voice quality will be as good as the weakest link in the chain. So if the other person is on 2G/3G, the extra info that is being sent by Jio for your voice will be "dropped" by the recepient 2G/3G network.
JIO to JIO I have seen the fastest call connectivity and good audio quality. but not everyone is going to talk JIO to JIO all the time. It has to be good cross operators also. BTW within seconds I called the same no from Idea and it was working fine. I was in good network area while using JIO so network coverage was definitely not an issue.
Lets face it JIO is good but not perfect. Call issues are there and being faced by not only me but many others too. So no point in defending them without reason. I know you are an employee but I am not against JIO. I am very much looking forward to shift my IDEA plan to a lower rental and use JIO for data.
