Can you Facetime from Sprint to AT&T?

I'm getting an iPhone from sprint and my friends have an iPhone via AT&T. Can I facetime with them?

Yes. Any Apple product can FaceTime with any other Apple product that has FaceTime.So, you can FaceTime with a Verizon iPhone, a Virgin Mobile iPhone, or even a Straight Talk iPhone. You can also FaceTime with a Mac computer, an iPad, and an iPod touch.

Yes you can cuz both of them are iphones but i think you might have to pay more

I don't see why not. FaceTime is an Apple to Apple thing, doesn't matter which carrier.

Any Apple product with Facetime capability can do so as long as Internet is present. A MacBook or iMac can Facetime iPhones, iPads, iPod touches… As long as all of the above are connected to data or Wi-Fi, whichever is applicable.

Yes, even over cellular data.

Please answer mine.
