Idea is one of the best network provider in tamilnadu , which provides very cheap tariff for their customers , as per my opinion the idea has the best tariff and its internet surfing is best than other networks when the area is covered under 3G covergae , when there was no 3 G coverage that speed was satisfied to me and the tariff is very good and suitable for middle class bachelors and families, But when I called the voice clarity of the network is not worth and there was some voice breakage, during the voice call , In my area they dont even support for video call! But when they show focus on it , then I will port in my family to this network, My general review is which is best for middle classes!
