In my Opinion Vodafone Mobile Operator has been not only the network of india but also about to be one of the leading network in the world because of its branch expansion in India, Qatar etc. I had & have my vodafone sim at my home. It is providing its service nicely. After 5 months when I came to Qatar for my own domestic reasons, again I got the chance to to use the vodafone service. Upto this time making contact to my family & friends at home I haven’t found any disturbance in Vodafone Network. Still now I am in Qatar & enjoying same service without disturbance.
