So, Facetime over cellular data networks has been available to some AT&T unlimited data customers since late November.
What about you? Is your iPhone able to use this much-anticipated feature? How do you know? Well, read on, and we’ll show you.
First, launch the Settings app with a tap, and scroll down to Facetime. Tap the Facetime tab and you’ll go to that preference screen. You can toggle Facetime OFF or ON at the top of the screen, sign in with your Apple ID, and then decide whether you’ll be available at your iPhone’s phone number, or any email addresses you add. You can also set the Caller ID to your phone number or any verified email address.
Near the bottom there, that’s what we’re looking for. Toggle the “Use Cellular Data” switch to ON, and see what happens.
If it simply stays ON, you’re allowed to use Facetime via cellular networks. If not, you’ll get a big badge notification, asking you to contact AT&T. Whether you do or not depends a lot on your tolerance for corporate help line menu trees. I hate ‘em, myself.
Now you know, and knowing is half the battle.
