I think vodafone is giving us a very poor network in last 2 year. I am very angry for this problem. I think vodafone mobile operator is bigest company in india but some place deprived to good network by vodafone. I say, before 2 year the vodafone was give us smooth network. we were very happy to vodafone at that time. I am using this network since 2010. I still using vodafone but this time I am very upset to vodafone for bad network.
