AT&T has changed its mind and will allow FaceTime calls over cellular without a Mobile Share plan, according to an announcement. The option will still be relatively restricted however, limited to LTE-equipped devices on tiered data plans. This excludes people with grandfathered unlimited data, as well as owners of any Apple hardware older than the third-generation iPad; exceptions are being made for people on special plans for the deaf and hard-of-hearing. Cellular FaceTime should open up within the next eight to 10 weeks.
