FaceTime over AT&T's 4G (you know, 3G) on my iPhone 4s (with a 2GB data plan) was enabled as of a few days ago. Haven't checked the settings since then, but I just updated to iOS 6.1 from 6.0.1, and after a message came up about saying that the iPhone was now using the new iCloud email address for iMessages, I decided to check on FaceTime, and it appears that the cellular data option for FaceTime is switched off again (and I can't enable it, just shows the 'call AT&T' popup). I don't really know for sure if I can blame iOS 6.1 because as its been a few days since I checked the setting it could be coincidence.

What do you think? A glitch in AT&T's system that accidentally temporarily enabled my 4G FaceTime? Something about the update turning it off? When I asked AT&T, they were surprised that it was even working at all a few days ago.

The same thing happens on an iPhone 5. Mine has a grandfathered unlimited plan that worked with FaceTime over LTE (this was a reason for purchasing the 5, in fact), but since upgrading (which changed my caller ID for iMessage and FT too) LTE FaceTime is disabled. –  raxacoricofallapatorius Jan 31 '13 at 5:45
    
Can anybody else confirm this or figure out a way to turn it back (like would changing caller ID settings work?)? –  kal-al Feb 1 '13 at 23:57
    
you have to wait AT&T to update its cellular settings. –  Raptor Feb 2 '13 at 9:30
    
Have you tried restoring? –  Shane Hsu Feb 2 '13 at 14:11
    
I have only tried disabling @icloud.com in FaceTime. I'd rather not go through the hassle unless someone else already knows that it would be a solution. –  kal-al Feb 3 '13 at 2:45

According to AT&T, before they officially began turning them on, some devices accidentally were switched on and then they turned them off, and that the actual rollout will be over a few months.

It isn't exactly iOS 6.1 and it sounds like AT&T at it again. I updated my iPhone 4S to iOS 6.1 yesterday as well and my Facetime over Cellular is still enabled. I am on a shared data plan, though, which has always - since iOS 6.0 - had the option to Facetime over Cellular.

I think AT&T's response when you asked them shows who is ultimately at fault here. Even though 6.1 isn't exactly at fault, it is possible that AT&T hasn't fully opened the possibility to Facetime over cellular to users with data packages like yours, and that upgrading to iOS 6 somehow re-instated that until AT&T does better opening it up.

I'm giving you the bounty since, well, you're the only one who I can give it to. And you were close. According to AT&T it wasn't the upgrade that triggered it, so I guess that was a coincidence, but that they accidentally turned it on, and then turned it off, before they "officially" started the "rollout". –  kal-al Feb 7 '13 at 3:32
    
Thanks, @AL. When I saw the bounty on this question I started to look into it again. But I didn't get very far as I don't have access to a tiered data plan iPhone. If they haven't already got cellular FaceTime going, I hope they do quickly. Either way, I'm glad you got it figured out. –  bassplayer7 Feb 7 '13 at 13:20
