I am pretty sure it can but I need to make sure. I am planning on going on a 6 month hiatus. All I am going to take is my Amex, iPhone 5, and I have access to deals on plane fare to travel between cities. I would like to stay in nice hotels and enjoy NYC, Boston, Miami, LA, Shanghai, London, Dubai, Hong Kong, and Paris. My iPhone 5 is unlocked and if that's all I need to do, if I also have my Amex with me, I should be set! Thanks in advance for your reply and please no hurtful comments.
