Is facetime free on iphone 4s?

Is facetime free from an iphone 4s to an inphone 4s or is there a charge?

Yes it is but you have to be connected to Wi-Fi

Its free when your on Wi-Fi.
it uses your data when on 3g.

Now available over cellular networks, but only with a charge. Wi-Fi is still free.

Only if used via Wi-Fi.

It is free but can only be used when you are connected to Wi-Fi
in the new ios 6 update, you can use facetime over your data connection

  • What's the earliest/ cheapest type of ipod/ iphone I can use free Facetime with? Most of my phone bill goes towards texting and phone my girlfriend, so it would be much cheaper to just buy whatever I need to use Facetime or whatever it's called to do video calls over my Wi-Fi. What's currently the cheapest model capable of this? But which model of ipod? The very first one?
  • My iPhone froze during FaceTime? I was face timing and it froze out of no where. I tried everything to holding down both buttons, and trying to turn it off but nothing will help. Please give me a good option to help unfreeze it.
  • Is it free to facetime someone out of the US? I got an iPhone 5s a few days ago and i was wondering if it was free to facetime? I facetimed someone from Italy today (using Wi-Fi) and my data is off. I heard it was free but i don't want to mess up my phone bill if it actually isn't free. Can someone explain it bc i need to know.
  • Is Facetime free to use between different countries? I live in the UK and can Facetime my sister in Australia with the SIM card in my iPhone but when I tried it without the SIM card it wouldn't let me do it. This makes me think I'm being charged for it. Any thoughts?
