I have tried vodafone fo 2 years.its worst mobile network. No good network coverage in good reputated areas just like Dlf cybercity guragon. I face many issues like voice breaking, call drops, peoples call me but they didn't reach me due to network mode.
On 3G mode the network is worst. Even I didn't make calls & internet services are poor. Many times I call customer care & log the complains but I didn't recieve any response.
Vodafone is a worlds no 1 mobile network. But in india its perfomance is bad.
