Is iMessage free across countries?

My best friend has just moved to Germany and I'm from England. We both have iPhones and I want to know if iMessage would be free for us? Is it only free if we use Wi-Fi or is it always free even using 3G?

Imessage is always free, even internationally. Make sure you turn off the option that says send as regular message if imessage not available (or something like that in your settings, so it doesn't send automatically in case imessage is down for some reason).

  • Rainbow lines across iphone screen? I got my iphone 4s about a month ago and i've had the lifeproof case on it since day 1. I have never dropped it, or gotten water on it etc. Today i was in the midst of typing a text message, when i noticed some multicoloured lines going horizontally across my screen. When i went to my home screen i noticed that half of my screen is completely like that. Everything is still fully functioning for the time being, but its really annoying! How do i get rid of this?
  • Is iMessage free if you text in other countries? I'm from the US and my friend is from Sweden. We both have iPhones and use iMessage. Would it cost extra for us to iMessage each other?
  • 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?
  • IPhone 4S has weird lines across the screen I have dropped my iphone on carpet and it landed on the case but now has weird blue, yellow sometimes red and white lines across the screen. Help? Will Apple replace it? Can I fix it? Is there a repair place that will fix it?
