Vodafone is a reputed mobile network brand on top in India. It may have better network coverage in big cities but when it comes to rural region network disappears suddenly. In yavatmal district of Maharashtra I have faced many problems about Vodafone's network in rural areas. And one most important thing now everyone is switching from 3G to 4G as I am using Vodafone from many days 3G speed was better than that of 4G
So if you want better network and speed then forget about Vodafone.
