Idea 3g Reviews

Idea is advertising that their 3G tariffs are now at least 90% cheaper than before, so they maybe which I am not sure of, but the main question is what is Idea 3G like regarding its performance. Phone wise I know that there are generally coverage problems and voice quality is not so clear, so I was wondering whether the 3G service was better. The reason I am asking this is because I have a spare Idea sim card and am thinking of activating 3G on it.
