Sprint has joined T-Mobile USA and AT&T on the Google carrier billing wagon, offering support for Android users who want to charge app purchases to their monthly bills. In a phased roll-out over the next few days, Sprint users will be offered a drop-down menu when purchasing apps, allowing them to choose between charging their credit card or “Bill my Sprint account.”

Google has been working on Direct Carrier Billing for Android devices for the past year. In addition to its American carrier agreements, it has also partnered with NTT DoCoMo, KDDI and SoftBank in Japan. According to Eric Chu, Android Developer Ecosystems at Google, the company sees direct carrier billing as a “key payment option” and will be continuing to partner with more carriers around the world, not least in markets where credit card penetration is low. Writing on Google’s official blog, Chu said that further announcements of new payment options would be made in the coming months.
