Does imessage work internationally?

Can you imessage someone who lives in a another country for free? We both have iphones. Also, does it have to be connected to the Wi-Fi or does it not matter?

Yes you can & yes it does matter if using Wi-Fi or not since if you are not you would be charged under your data plan.

Whether Wi-Fi or celltower its free either way.

  • Will iMessage cost me when I'm traveling internationally but on Wi-Fi? I have an iPhone 4 and I'm in Canada however my standard plan just includes the states. I'm currently connected to my aunts Wi-Fi and I wasn't sure if by using iMessage I would have to pay international roaming rates or if it would be free still since I'm on Wi-Fi?
  • Will FaceTime work internationally? My sister's boyfriend was deported like a year ago and she wants to send him and iPod or iPhone so he can FaceTime with her an their daughter. ISome people said it would work but it's pretty far(he lives in Costa Rica). I know he has Internet connection but Skype didn't work when we tried.
  • Is it free to use IMessage with your data internationally? Or is that only using Wi-Fi? I have a friend who is from Canada and I'm from the US. And he has an iPhone and so do i. He said that we can text on our phones for free internationally using iMessage, but what I've heard is that it's only free if you're using Wi-Fi. What about your data? Is it still free when I go out and am away from Wi-Fi and use my data? My messages still appear blue when I message him with my data but I'm concerned that it's not completely free when doing so.
  • Is iMessage on iphone free internationally? I'm going out of the USA if a few days and is iMessage free internationally? Will i be charged if my leave my "Cellular Data" is on, meaning i will only be using Wi-Fi?
