Vodafone 3G datacards is a leading mobile network in India.The prises are highes of all network and the network is completely disaster.The voice call quality is still worst as there are other companies which are giving HD call quality.I have purchased my Sim with Adhar Card but they are sending me a message continuously that as per govt rules Adhar link is neccesary please come to near by store or your card will be off.There is no goverment notification regarding adhar card is necessary in simcards.Customer support is very rude and behaves like vodafone is monopoly in India.
