Vodafone is one of the worst network. As im using the same network I faced many problems, many times.I dont prefer that network to anyone.I think it has very less towers, am not getting a proper signal even in towns also.The offers are also very bad and the call rates are very high.I hate that network.Firstly I am using the same network.Later on I ported from that network.The call rates does not depend upon seconds we talk, it charges according to minutes.It charges 80 paise per minute and the data speed and data offers are very bad.
