FaceTime is one of the most popular features in iOS devices. A very convenient way for two people with an iDevice to video chat, without the hassles of signing up or anything like that. When Apple launched Facetime it was only compatible with WiFi networks and not cellular. This was probably because networks at that time were not cut out to handle such a load. But with iOS 6 Apple officially enabled FaceTime over cellular. All network allowed unrestricted access to this feature apart from AT&T.
AT&T kept FaceTime over cellular only for users with a shared data plan. Those with grandfathered unlimited data plans were left out. It was a strange move that brought AT&T even more flack. Now however it seems as if the network has had a change in heart. Users with unlimited and tiered data plans are now reporting that FaceTime over cellular is a go on their iPhones. It’s not available for everyone just yet possibly because AT&T is slowly phasing it in. If it’s not enabled, reboot your phone to try again.
Call it an early Christmas present or anything else, but it looks as if users of America’s biggest cellular network will finally be able to enjoy FaceTime over cellular.
