Idea mobile operator is the best mobile network in india and it gives best tariff plans for data plan , local std plans and it also provide best sms tariff plan and if i talk about its network coverage it is good and u cannot feel problem in even remote place earlier idea network was not good in rural areas but now it has covered all rural areas and i never feel network related problem in village area. especially if i tell u its 3g data plan it gives cheaper data plan and if you are using it as a regular customer u can find a lot of offers and i am enjoying its offers in 2g plans sometimes gives 2gb gata only in 97 for 28 days and sometimes in just 9 Rs. tariff gives 90 days local call tariff so at last i say it is the best network
