I have been using vodafone prepaid and post paid connection for 6 years and 2 years respectively. Both of the services are good. But postpaid service is better than any other postpaid mobile operators in India. Because they provide very good plans and customer supports regularly.They have wide range of networks.Prepaid connection is also better, But there is also other operators like idea, airtel etc which keeps the same quality.But in the casse of postpaid Ii only recommend vodafone.
