Hi,
My family is traveling to Japan next week. I would like to have communication method between my family for situations like "hey, where are you?" kind of short conversations, and I would also like to be able to call local Japanese numbers. We all have iPhones and We don't need to call to United States when we are in Japan. Is iMessage still gonna be free in Japan and work? What would be the cheapest way to go this? We will be in Japan for only 2 weeks. I also be able to see emails too. Any tricks, experience story or advice helps. Thanks!
