I am from mumbai And I usually travel by mumbai locals. In my 40 mins of journey, jio internet works for only 10 mins. Rest of the time, I get full network bars but no internet.
I am also facing severe call drops even when I am stationery. I cannot talk to anybody for more than a couple of minutes. It goes from 3 network bars to "no service" , and then it comes back again to 3 bars. And this is when I am stationary.
Spoke to cc but they blame it on my phone. I use iPhone 6. Could there be some merit in what they are saying ? Or is there anyone else in this forum from Mumbai who experiences similar issues like me ?
Can't speak for Local trains, but the network is pretty spotty at my Office which is along the Western Express Highway. Meeting rooms are dead zones where I get absolutely no signals. Haven't faced any call drops or Internet issues when I'm in full coverage though.
