The link isn't working. Help! I'm going to Central Europe this week...and have the same question/issues.  My travel companion and I want to be able to text each other when we need to meet up....but we'd have to have wifi to retrieve texts or voice mail w/GV, yes?  But an AT&T international plan would require the phone to be on to get a text message and that could potentially be very expensive. Any help would be appreciated.
