Idea network is a good network enough. its network is always there in outer area too . and when I travels diffrent city then also idea network still exist properly.
Its lil bit expensive the other company sim and its net pack 2g , 3g , 4g all are expensive so you can use this sim if you want proper service but if you want a cheap plans so you should go on tata docomo or airtel ! but idea is expensive but still good because of proper service ! thank you ! .
