I know this is probably not the first time that somebody ask this kind of question. What is the best way to take my phone out of U.S. and don't get a $500 bill? We have 2 iphones in the family and we are planing to go to mexico on vacation for a couple of weeks. I just want to use it for basic features like checking e-mail, some web browsing and maybe a few calls. I don't mind to do it on a wifi spot at all if necessary. Any advise?
