  • Which camera should I bring? Studying abroad in London/Travelling Europe? I have these options: a DSLR Nikon camera, a Sony videocamera (small), or should I buy a digital camera? In addition, i'm bringing my iPhone 5s, which has pretty good quality as well. I'm just afraid I'll lose my DSLR, should I buy a digital camera or take the small videocamera? Suggestions? I will be studying for a semester in London and traveling to a few countries in Europe as well.
  • What should I turn off/on on my iPhone when travelling abroad? I'm going to Germany for a few days and I'm taking my O2 Pay and Go iPhone5 but what settings should I turn on or off so I don't get charged a stupid amount or use all my top up money? I'm guessing data roaming should be turned off for a start. I do want to post pictures while I'm there though too, should I only do this when I can find a Wi-Fi signal to connect to?
  • What are the iPhone restrictions for travelling abroad? Hi:-) I'm travelling to Italy tomorrow for a week. I have an iPhone 4S. I'm looking for a detailed explanation of dos/don'ts with my phone throughout the entire journey - particularly regarding the Internet. Include: - Travelling on a plane to Italy. - What to do with it once I get to Italy. - What to do during my trip. - Travelling home. More info the better, and the main focus of this is No Surprises On Phone Bill!
  • Travelling to turkey, which data plan? Hi, I'm travelling to turkey in a couple of weeks (the part of Turkey in Asia) and I need to get a sim for my iphone that will take care of my texts, calls and internet abroad. I'm only going to be in Turkey for a couple of weeks and my current carrier (3 mobile) doesn't have any international plans. I was wondering if anyone knows a carrier which offers good, cheap international plans.
