I have been using idea sim card and for the past few years it should be paricularly said that idea provide the best internet facility in india
Other excelent feauture is that they provide good customer service and when we register a compaint in their in their customer service number it usually get solved soon
The only problem I think idea is having in our location is that the cost of most of internet plans are somewhat high compared to reliance and other similar networks in my location
Those who cares much about the service especially internet and doesnt care much about few savings in plans cost for them idea is the best network in INDIA
