AT&T is allowing more iOS users to place FaceTime calls over its network for no additional charge.
Previously only available for customers with Mobile Share plans and those using an LTE device on a tiered plan, now AT&T customers with non-LTE tiered plans can also make FaceTime calls over AT&T’s network for no additional charge.
AT&T customers on unlimited data plans are still unable to make FaceTime calls over the network
FaceTime over cellular originally launched on AT&T in September 2012. AT&T’s Mark Collins says that the company wanted to roll the service out gradually, in order to have “minimal impact on the mobile experience for all of our customers.”
