Vodafone is one of the top mobile operator but the rates of the services are very high.One cant afford a 3g plan for entire month you have to go with 2g most of the times.
Call rates are high ( as compared to other networks) upto 1.5paise/sec .The only thing that is good about vodafone is the network coverage & the customer care service, you can find its nw available everwhere.
Sometimes they come up with great plans but again it is once in a blue moon. : (
