In my opinion I must say Reliance mobile network is the worst mobile network you can ever have. As we know reliance is biggest company in india but the thing it's the biggest company but it doesn't even provide a good network. Funny part is biggest company has a worst network issue. Internet speed is also too low. It's worst than 2g.
Let me tell you something once I was coming from my village on my bike. My bike broke down in the middle of the way. The biggest problem was, There was nobody to help me. I just had one source to help my left. I was my phone. That time was having a reliance sim which cheated me. It wasn't even taking any network. I was too disappointed to have it.
At the last I got it ported in BSNL.
