After ruffling plenty of feathers back in August when it announced that FaceTime over cellular would only be available to users on its Mobile Share data plans, AT&T has decided to loosen those restrictions a bit. Today, the carrier announced that customers on its new tiered data plans will be able to use FaceTime on its network, but only if they have LTE-capable devices.
This means that customers who still have grandfathered-in unlimited data plans are still out of luck if they'd like to FaceTime without using WiFi. Also, owners of non-LTE devices -- so, basically anything before the iPhone 5 and the third-generation iPad -- need not apply. You don't need to have LTE service for your device, however, which is at least some good news for those who don't live in AT&T's LTE coverage areas.
If you meet the new criteria, you'll be able to start using FaceTime over cellular on AT&T in eight to 10 weeks.
