Me being a tech enthusiast I always used idea as my daily sim card and the best part is after jio approaching us idea became cheap and cheap and is the best service provider in india I am satisfied with its network range and recharge packs.
Overall a great network u can trust upon no call drops clear crisp voice but the local idea offices are not polite minus points for that they are a hell of people who dont know what to do except that I would give Idea 4 stars for performing good in the network department.
