when I turn airplane mode on then wifi on and go to facetime:// 10 digit phone number it gives me the option to facetime then the screen goes black.

I dunno...works fine for me and others I know who have tried it.

I did try it with a non-facetime iPhone number just to see if it would try to connect.

I'm going to see if my friend is awake and try and facetime her.
 
This explains alot, I was surprised to see 0,29€ on my online bill even though I didn't send a single text or called anyone, I did however press Facetime accidentally in the contacts app, but I immediatly stopped the connection...
 
You're not charged for incoming texts unless you read them.

Bull!!!!!!! If that is true explain how when I had a broadband card every month I would have 2 -3 txt messages on my bill. The card had a phone number thAt was probably someone elses before so they continued to send texts. I never saw one txt, there was no way to see one. Yet I was charged for everyone of them.

I also tried with a non-facetime number and it shows my face and then pops up an other person doesn't have FaceTime message.
 
He said in order to enable FaceTime, I had to turn on FaceTime in the settings, which would in turn send a text message to Apple, and then I could restrict text again after that.

Thanks for this information. So the phone sends a silent text in order to activate FaceTime. Makes sense now.
 
honestly...wtf does sms/mms have to do with facetime?

The voice connection can't transfer any data between the phones, but to connect to each other, you need to send some information to the other phone about how to connect to each other.

You can't send that over the data connection without knowing the information you are trying to get from the other phone (catch-22).

SMS is the easiest way without requiring that Apple be used as a relay for every single call. Even if you have Apple as a relay (for cases where UPNP and the like fail), sending a token to the other side to use to connect to you through the relay is more secure and anonymous (they don't have to send personally identifying information to Apple's servers to tell them which phones are trying to connect to each other).
