T-Mobile subsidiary GoSmart is offering its wireless customers a little something different: free access to Facebook even if the users don’t have a wireless data plan. According to AllThingsD, the promotion should launch next month and will cover “anything hosted on Facebook itself,” include Facebook messenger. While there has been a lot of talk over the years (most of it from billing systems companies) about carriers charging more or less for particular apps, a lot of these billing concepts (like AT&T’s 1-800 data concept) have raised red flags among the network neutrality brigades. The concept of offering free data for one app is a new one here in the States, and it will be interesting to see how it’s received by consumers.
