US mobile operator AT&T last month launched carrier billing for Android users on its network. The announcement was made on Google’s Android Developers blog. An AT&T user with an Android handset can now charge their Android Market purchases to their monthly cellular accounts “with only a few clicks”, says the posting. “In addition to the availability of AT&T and T-Mobile US carrier billing, we’ll continue to partner with more carriers to offer carrier billing options for their subscribers”, the blog posting adds.
