Vodafone has very bad network, I complaint vodafone that its network goes out during travelling, they replied that they dont found any issue with the network. Even when I am at home ( open area) the network goes eventually. When I complaint they ask they will send tecnician to see the issue and after some time they called at my phone and tell me that the network is working properly at my area. I dont know what vodafone want to say they mean I have plenty of time to complaint them? I finally purchased a airtel sim and its working outstandingly and no issue found even in metro I will soon portable my vodafone number into airtel.
Conclusion : vodafone should do soomething for their network and they should be customer friendly else they will soon loose their customers.
