Play Store carrier billing is now available for Idea Cellular subscribers in India.

From the Google India blog:

This collaboration with Idea Cellular is the first time Google Play has offered direct carrier billing in India. Like with lower minimal pricing and pre-paid vouchers, we hope to make it easier for people to pay for the content they want on Google Play. And we also hope that this will help nurture the developer ecosystem in India, so that developers can grow their businesses on Google Play connecting to Indian customers.

Carrier billing is live for both prepaid and postpaid customers. Prepaid users will see their balance getting deducted automatically upon purchase of digital content, while postpaid users will see all charges added to their monthly bill. If you're an Idea subscriber, you should see the carrier billing option in your Play Store payment settings.
