Is there some way to text message with international friends? I have a sim card but it is only used for data, not for voice or texting. Besides, when I leave the country I wont have the international numberanyway. I can't text internationally with Google voice and I don't think they can text an American number either. Besides email, is there a way to conveniently text either other Most have iPhones so I don't think googletalk works for them.
