There is another issue I’ve face with Jio, especially when I did STD calls to my friends at Chandigarh. Many times the call gets connected, the person picks up the phone, I can hear him fine, but no matter how much I scream at my end the person on the other end of the line hear nothing but dead silence. No matter how many times you call him, the same things will keep happening unless you calls you back.
This is a another supper annoying issue you are going to face if you start using Jio as your primary number. And just like all other issues mentioned here, no one knows when this issues are going to get fixed.
