Vodafone is the most mobile operator I ever used. When I came to pune I asked from one of my friend that which network is good in maharastra so he suggested me to take vodafone but it was a bad decision, vodafone is worst in matter of intetnet, the only good thing about vodafone operator is that its network coverage area is good. Now coming to call rates, call rates are higher than other mobile operator as I told you before that internet services are pathetic so I will never recommend to use vodafone mobile operator, there are so many mobile operator like BSNL, Airtel and idea go for them
