AT&T has finally changed their mind on the FaceTime over cellular on their LTE-enabled devices.
It’s going to take about eight to 10 weeks for this change to take place, they say. Apparently, their excuse was that they didn’t want to put strain on the network without being fully prepared:
“With the FaceTime app already preloaded on tens of millions of AT&T customers’ iPhones, there was no way for our engineers to effectively model usage, and thus to assess network impact. It is for this reason that we took a more cautious approach toward the app. To do otherwise might have risked an adverse impact on the services our customers expect – voice quality in particular – if usage of FaceTime exceeded expectations.”
Gizmodo points out that grandfathered unlimited plans won’t get to enjoy FaceTime over 4G. Anyone with a pre-LTE iPhone or iPad won’t get to use it, either. They also point out that you should be careful, because it’s a major data killer.
