Google has launched carrier billing facility for Indian Android users. I found the full list of service providers which support this facility. Idea is the first telecom company in the list and the rest(Airtel, Vodafone, Telenor etc..) are after that.
You can purchase anything from Play Store with this feature. Google already allowed this feature for some countries.
Here is the Google’s word : “We are in the process of adding direct carrier billing to Google Play in India on Idea Cellular so that people can more easily pay for their favirite content,”
So, Now Indian android users also can buy apps, games and products from their Play Store app via there telecom account.
They already started allowing this feature on Play Store app, Update your Play Store app if you don’t get this feature on your phone from below link.
