Vodafone is the most popular mobile operator in india. It has good quality network, which makes our life easy. Vodafone group is working all over the world and it has been providing ita service for last 25 years in the world. Its operating income aroung 19.67 billion. Best network and good service. I also have been using vodafone since that day when Hutch got changed into Vodafone. It is little bit expensive to comparing other mobile network in india but providing great service. I like Vodafone.
