• Carrier billing allows mobile users to buy digital goods like ring tones, music, apps, e-books, and in-app purchases by adding the cost of the purchase directly to their mobile bills. While carrier billing is very simple and seamless from the consumer's perspective, it depends on a complex set of relationships between wireless carriers, app stores, platform vendors, and app developers. Those relationships also vary substantially country by country, depending on each market's mobile ecosystem.

Carrier billing is seeking to handle a bigger and bigger slice of this market, much of which is funneled through credit card purchases on the main app stores, Google Play and Apple's App Store. Carrier billing can work within the app stores and outside of them, but so far only Google Play has shown an interest in working with carrier billing.
  • Carriers are beginning to lower their once-prohibitive fees for powering carrier billing transactions, in the hopes of seeing revenue explode as more people adopt it as a payment method. Mobile operators charge fees between 25% and 40% of the total cost of purchased goods. But as carriers struggle to maintain revenue, and [...]
