I think vodafone is the one of the best network of India. You can say that vodafone is too much costly from other telecom companies . But the main task of any telecom company is to provide better and everywhere availed network and fastest internet . In both parameters vodafone perfomance is not only satisfactory but also excellent. Vodafone is for those persons who are not night owls means they only need mobile network for professional work.
For a person belonging to any sector if he or she may have to attend 10-20 professional calls per day then it is essential that you should have a working network. Internet which is essential need for modern era can be fulfilled with fastest internet . Peoples are modernizing themselves very fastly in growing India . 2G is subject of previous decades now people want fastest 3G network . On all these parameters vodafone is excellent . Some people say that BSNL3G plans are very nominal than vodafone and it is true but BSNL3G is not available everywhere and net speed is not comparable to vodafone. Lastly I only say that on all above which I have explained you can trust vodafone undoubtly.
