A couple of weeks ago AT&T confirmed that they would be activating FaceTime-Over-Cellular for their customers, although this was limited to customers on a tiered data plan. However rather interestingly, it seems that according to some reports via the MacRumors forum, AT&T might have extended FaceTime-Over-Cellular to all of its subscribers, even those who are on grandfathered unlimited data plans which have since been abolished by the carrier. According to the post:
“In a recent thread we were discussing AT&T members getting facetime with LTE devices and tiered plans. However I noticed today that I have facetime over cellular and I have an unlimited plan on my 5.
I just turned off my other phone, a 4S and turned it back on, only to find the switch flipped to ON for facetime over cellular. Both phones work perfectly over cellular.
I also checked a few coworkers phones, all now have FT over cellular.”
Since AT&T has yet to make an official announcement regarding this matter, this could simply be a mistake on AT&T’s part and that they did not intend to allow FaceTime-Over-Cellular for all their customers. In any case if you have an iPhone 4S or iPhone 5 and you’re on AT&T’s grandfathered unlimited data plans, let us know in the comments below if you have your FaceTime-Over-Cellular activated as well!
