I am fed up of airtel's unfair usage policy as i have 649 plan, so when i tried to check mtnl Delhi website as I live in gurgaon.it didn't open, tried several times. but when i tried a proxy website it opened. Does it mean that airtel has blocked its rival's site due to mtnl's super competitive prices or there could be any other technical reason? can airtel do it legally? I am not a very technical guy kindly get your say in..
