Good and best network is idea because I have been using sim card of idea company last 3 years and whenever I should go to roam in my native place or with my friend to enjoy outside I should take idea sim only because I never and ever get a problem in idea card and they have fantastic network and I recently buy for my wife and my all friends are using this network and idea company has tremendous network of internet but some place the internet working slow. I really recommend this network.
