I am using VODAFONE sim since 7 years the Vodafone provide best service. the network is full any were we go the in networking is best even at the corner of the city the online recharge, data bonus and other benefits are best. The 2G is best for me when I am using Facebook or Twitter 3G is good for downloading app videos and any other thing you need And 4G is killing fast like blink of an eyes the app gets download so faster. I feel this from my bottom of my heart that the Vodafone is the best ever networking service
