Idea is a pocket friendly mobile network.promo packs and call rates are very cheap and pocket friendly.i travelled to many states and found idea can be found in nearly every places.the coverage is good.but voice quality is weak in low signal.internet service is though can be taken in a cheap amount, the internet speed is also cheap.speed is poor.if some one, has full network in mobile , can not have any problem with idea.for speed and low signal voice quality idea is poor.but, can give network coverage nearly in every area.not a bad network at all.
