Vodafone is comparatively very costly and dont provide good service as per the charges.
Specially they almost loot your for Roaming charges and switching over plan they will take long time to give them selves opportunity to earn more out of you. They charge unstintingly for their unfair benefits. And Vodafone stores at KharGhar, Navi Mumbai dont care about Que and genuine customers. Vodafone is the most irritating service provider.
I am switching to Tata Docomo from Vodafone. Vodafone is worst and very costly service provider. Though I dont know how will be the Tata Docomo but here the postpaid charges are under 1000 INR. After tata fail I might end up using prepaid only, that too of airtel.
