I have vodafone number from last 7-8 years.I think that it is best networking system.Vodafone company also give awesome offers which are enough to explain it.It 2G speed defeat the other 2G network.I like it alot.It is not much costly as the other networks are.Its double validity packs attract everyone.We Enjoy more data on lowest prices or we can say that double data on very cheap rates.Call rates are also available as a justifiable prices.
