With other national (and international) carriers slowly enabling carrier billing on content purchases, it was only a matter of time before the second largest network in the States would start adapting said payment method. And while AT&T’s been offering the service for application buys through Google Play, up until now it’d been leaving out all media-related goods. Luckily for some, the Rethink Possible outfit has announced its plans to begin offering carrier billing options inside Sammy’s Media Hub, with the Captivate, Galaxy Exhilarate and that modish Galaxy S III to be among the first to help kick things off. Meanwhile, everyone’s favorite phablet (aka Galaxy Note) and the somewhat aged Galaxy S II will be able to join the others as soon as they swallow up an upcoming software update. More importantly, are you planning to add those movie purchases to your monthly AT&T tab? Say the word in the comments below.
