Is iMessage & FaceTime free to use abroad?
Hello everyone, I am currently in the UK (United Kingdom). Earlier next month I will be going on a Spanish Exchange trip with college to Spain. I would like to stay in contact with my parents/friends over iMessage and FaceTime. Is it free to use these abroad without getting a HUGE bill? I've read on some other websites that you need a Wi-Fi signal to connect to and then you are able to use FaceTime and iMessage. Is this true? Has anyone had this experience abroad? I am going to visit the Apple Store next week to double check with the genius' that work there, but I would like to be sure from this website too.
Another question: Before I go abroad, what do I need to do on my iPhone to stop me from getting charged alot?
Thanks everyone!
