Idea is also popular brand of Aditya Birla Group. It is covering most part of India after Airtel. Idea custumer service was good but in charges and billing matter, it is not so good. Biggest problem of Idea is network coverage issue. Whenever you make a call, network was not available. Many time Idea deducting charges without a call. So, I am not satisfied with Idea service. Also, I personally not prefer to others
