AT&T will expand FaceTime over cellular support. It means that more customers will be able to use the FacTime video chatting service over its cellar network. In the past, FaceTime was only available for “Mobile Share” customers. The rollout will take place for next few months. Both Verizon and Sprint both already offered all iPhone customers the FaceTime service over the cellular network. For customers who have grandfathered unlimited data plan, still can’t use the features.
