Hello everyone, long time Android user here. Recently I converted my entire home over to Apple. I bought two new retina macbooks for me and my wife and a iMac for the office. I swapped my new Nexus 7 for an iPad Air and now the final piece of the puzzle is getting rid of both of our old Android phones in exchange for two new 5s. We are currently on Verizon and I will be staying with them, my question is that we are traveling at the end of next week to London for 5 days and then continuing on to Dubai for another 5 days before returing back to Arizona. I've traveled overseas once before with my current Droid Razr MAXX and when I did, I just popped in a local SIM card and used my phone. This worked ok but I had to trim the SIM card down because my phone uses some Micro SIM or something. Also my data would not work at all when I was there. I'm hoping that the 5s will work a little better when we travel next week. Will I be able to just pick up a SIM card in London and Dubai and pop it in and go? Or will I need to trim the card again like I did last time and will data work? I want to be able to pull up google maps and stuff while I'm there so that I don't get lost walking around. Any help would be appreciated. Thanks.
