Airtel sure knows how to make good ads..but their customer services in Mumbai, though attractive, are not upto the mark.SMS Messages typed in the night will reach the other person in the morning.Clarity is the only good part, but range is RARE.I even dont have range in my home!>If you are buying a new service provider, i recommend Orange, as it has excellent range and has responded with same offers that AirTel did.Orange is even more experienced in Mumbai.So go for Orange, or BPL or any other experienced service provider in Mumbai.AirTel will need some time, and only then venture into it.But one thing is for sure, AirTel is here to stay, and surely change our lives, but not this year.
