Users of the iPad 3 and 4, as well as the new iPad mini, will also benefit from FaceTime over cellular.
The service will be available for any LTE device on any tiered data plan when it launches in the next 8 to 10 weeks.
Here is AT&T’s official statement:
“AT&T today announced it will enable FaceTime over Cellular at no extra charge for iOS 6 customers with an LTE device on any tiered data plan. AT&T will also continue to offer FaceTime over Cellular to customers with any AT&T Mobile Share plan, as well as FaceTime over Wi-Fi, which has always been available for all customers. AT&T expects to roll out this functionality to customers over the next eight to ten weeks.
As part of its commitment to serving customers with disabilities, AT&T is also making FaceTime over Cellular available to deaf and hard of hearing customers who qualify for special text and data-only packages.”
“We decided to take this cautious approach for important reasons,” said AT&T executive Jim Cicconi. ”AT&T has by far more iPhones on our network than any other carrier. We’re proud of this fact and the confidence our customers have in us. But it also means that when Apple rolls out new services or changes, as it did in iOS 6, it can have a much greater, and more immediate, impact on AT&T’s network than is the case with carriers who have far fewer iPhone users.”
