I had very bad experiance from vodaphone mobile oprater. the network is also very in some area and automatically call drop and some time it is say not reachable this mobile number . vodaphone is a very big network service provide in telecom industry . I am visited many place in india but did not have any problem with vodaphone network . howaver , voda phone plan very good for user . but vodaphone network is poor . in the end I want to say that the company is init improvement. thanks
