I am using this Idea 4G sim card not more than 3 Months but, I have experienced that after Jio sim came into competition Idea has reduced it’s Internet and Voice calling charges. So I don’t know how it was earlier and how was it’s service, but I can safely say now that it is giving nice competition to Jio and customer satisfaction. As on my 3 Months experience I have taken another Idea 4G sim card.
