Hello friends as I said its a bad or worst experience with Idea. Using it for 2 years and never got a better experience.
Whenever I am on roaming or even in my home zone that is Darbhanga.
The another weakness is its internet service. Its bad and I don’t even became capable of opening a single page.
I often find the network absent when I try to call from a train or bus. Still giveing it 2 star as whenever it connects a call the clearity is quite nice. So, they have to work on the network only.
