Upon registering to this service, you can earn cash rewards in your PayTunes account every time you receive a call. When you register to this service, PayTunes starts running some audio ads on your caller tunes. When someone calls you, instead of the normal tring-tring tone, your callers hear the ad deployed on your caller tune and you get rewarded with 10 paise post completion of the call. You just have to pick your calls after 6 seconds.
Currently, Prepaid Subscribers of both Vodafone and Aircel can sign up for this Free Service by Downloading the PayTunes app (Click here to download) from Android Playstore. You can also subscribe through these web links:
