I am using airtel network for past 3 months and as per they said the data will fastest among the other networks. But it may only applicable for the pospaid plans. Because the unlimited plan is not even working well and even calls drop for a while. Don't know why they are telling its a fastest network. I am really fed up using the india's fastest network. Even my friends using aircel and other networks but they are laughing at me as am using the india's fastest network.
If we do speed test it will show that 25 mb/s like that but we are asking just give us 500kbps well. And that's more than enough
