I am pretty tech-ignorant. (OK i am completely tech- ignorant). I have my devices that I just expect to work and I am frustrated and confused when they don't. The only place on the planet I have ever been where my mobile phone did not work was japan. Is there anything I need to know/do before we leave to insure a working cell phone? I do have international plan on my phone. I think someone suggested it had something to do with SIM card or ???
