I am using IDEA since 7 year but have not any problem yet. I think it is one of the best network operator in all. It has very good offers and planes. It has lots of time full as well as more than full tlktime offers. I have also experience other but this is best. It has very nice internet planes. I got 7 days validity 200 MB internet just in Rs.13 lots of time in my offers. Recently I have internet plan of Rs.248 unlimited 2G internet in which I got more internet speed like 3G in 2G recharge.
This is best part with it. I have recharged with 40 and get 40 talktime whcih I am using for calling. It has low calling rates also as compare to other network. They are providing good customer support to everone, no waiting call for more time on 198. I will suggest this type of network to every user specially for internet user. Thank you IDEA.
