Since it was revealed that FaceTime over Cellular was coming to iOS 6 last summer, AT&T has been gradually rolling out the feature to different segments of its subscriber base.
At first, you had to be on a “Mobile Share” plan, and then it was opened up to LTE iOS devices on a traditional tiered plan. Back in January, AT&T gave everyone access except subscribers with grandfathered unlimited plans.
Now FaceTime over Cellular on AT&T will be available to all iOS device owners, including those with unlimited data, by next month.
