Idea is a smart choice I think. Idea is far far better than other mobile operator like Airtel, Vodafone and other mobile operators we have now a days. Idea give you better net speed, better call rates and give you most exciting offers too. Its 3G speed is far far better than other networks. I din’t use this as a 4g but I can say that is 4g speed is more better than other mobile operator. And its Constmer service is better than others. So at last I want to say if you are looking for a new operating system try Idea.
