AT&T announced on Wednesday it will enable FaceTime over cellular at no extra cost to any customers with a tiered data plan and compatible iOS device.
The announcement was made on the carrier's website by Mark Collins, senior vice president of voice and data products. The change means that iPhone 4S customers with tiered plans will be able to make FaceTime calls over the AT&T network.
"We have already begun updating our systems and processes and expect to start rolling the update out to customers on an ongoing basis beginning in the next couple of weeks," Collins wrote. "Customers do not need to do anything — the update will be applied automatically over the next few months."
FaceTime over cellular will not come to older devices such as the iPhone 4 or second-generation iPad, even if they are running iOS 6. But that's because the hardware does not support mobile FaceTime connections — a decision made by Apple, not AT&T.
Previously, AT&T had restricted FaceTime over cellular to customers who had switched to its Mobile Share plans, as well as those with an LTE device, such as the iPhone 5 or latest iPad, on a tiered plan.
AT&T came under fire for its initial decision, and the company was compelled to defend itself in a statement claiming its plan complied with Federal Communications Commissions that prohibit carriers from blocking services that compete with their own. The carrier argued that its decision was in compliance because AT&T does not offer its own competing preloaded video chat application.
AT&T began quietly activating FaceTime over cellular for more subscribers in November. At the time, some users who had grandfathered unlimited data plans said they too were able to use FaceTime. However, Wednesday's announcement indicated the ability will only extend to customers who have tiered data plans.
