I bought a new mobile phone and also bought a airtel 4g sim for internet using before two months. Han! First this network was work like 3G speed. Then I go to the mobile centre and talking about this operation. And they said Airtel wil start slowly. So, waiting and it start4G. I am so angry. But I bought it. So I used it. Then, this 4G network was working. And work speedly. But it not work in all places. This only working in my home. But when I going to any places this not working normally. Also it daily pack was some trouble. Because I seen 700mb balance in daily pack. But I started to use this pack and it was quickly finish. I think this is speed network. But the reality was really true. It was very trouble to my daily pack. But dont work in all places. This was very disappointed to me.
