Beware!!!!! Please dont by this
scheme. The biggest problem is - to call once on an average you need to
dial their toll free number 10 times. Once you get through this
you will have to listen to the massages about your balance and stuff at least
2-3 times. Its such a pain, even if you have bought 5 $ you will take
at least 6 months to spend this money because you will never get
their toll free number which is engaged eternally. If some one has
already purchased and if by chance you get through, finish all your
minutes at once so that you will not be frustrated on every call you
make home. Anyway I dont see any benefit from buying airtel as even
reliance is also offering 7.9 cents plan. Please please dont
buy.
However after having said so much I must also say that
their voice quality and billing is excellent. You can experience this
once in a blue moon as getting their line is next to
impossible.
