I am using idea service from last 5 years and I will say its best in Maharashtra. Network is the best and Service is also best no call Drops.
I choose this service because of the Network in village also I was getting full network which was best part.
We went for outing there also only IDEA network coverage was there.
I like in idea
Netwrok
Customer service
No call drops
best suited plans
Best 3G network
What I dont like - There is no such thing but I think they must keep their net packs at Low rates compared tho others. There was no billing dispute also I have seen there bills and I am totally satisfied with IDEA service and I will say I am happy Customer of IDEA.
