Look at these links, I made so many complaints regarding their non-existing 3G services. In last three months they just kept on making excuses and billed me. Finally they said there are brown areas in most part of Bangalore where we cannot get 3G signal which is eventually piggy backed on Airtel spectrum ( while their 2G signal is perfect). As and when I tried to switch on 3G on my phone I was not able to receive or make calls as signal dropped to one signal bar. Also phone had zero signal during transition from 2g to 3g. But at the same place with 2G I have perfect signal. So basically using 3G SERVICES of Vodafone is killing yourself at your own cost, as it ruins your voice calls and you hardly able to use data with poor speed.
Infact Vodafone has nothing called 3G which they are selling as world's best network. On top of that after 3 months of running around I was told by Nodal office that it is not feasible for Vodafone to provide 3G services when I warned them with legal action.
