Can I use iMessage on iPhone internationally?

I love in Canada and this weekend I'm going to the USA to do Xmas shopping. Can I use iMessage without being charged money?

As long as they have iMessage too, then there should be no extra charge.It'll just use data.

Yes, as long as its used on Wi-Fi. That's the same case anywhere.

  • 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?
  • What is a good app to use to text for free internationally for the IPhone? I'm going to Mexico in a week and I want to be able to communicate (text, calls) with family in the US while i'm there. What is a good app to download for an Iphone that would be completely free for me and the other person?
  • Use My Iphone Internationally? I have an Iphone 4s running IOS 7. My family and I are going to Europe for two weeks and I'd like to bring my phone with me so I can take pictures and keep in touch with my friends, HOWEVER I don't want any international charges for texting, data, etc. I want to bring it around with me to take pictured but ONLY would like to use it to text and use data when I'm on hotel Wi-Fi. Is there a way I can do this so I don't get charged?
  • 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.
