Idea cellular service is very good, but it's network frequency is limited. I'm using Idea SIM more than 3 years. In Idea app offer wall is very good. Like other service provider give 1GB data in 256, 251. But I always get 1GB data in 175/- and obviously 3G data. So always I prefer Idea service, little objection that it's frequency is limited otherwise it's better than others service provider.
