My iPhone broke abroad- what should I do next?

I'm studying abroad in France and my phone got water damage (I didn't swim with it but it may have been with a wet towel or something). The repair shop said that it is not repairable. My French carrier is SFR (in the USA it's Verizon but I have the SFR sim card in now). Is it possible to buy a new iPhone from them or will I have to wait until I return to the USA? Really do need a smartphone for school and communication purposes so what should I do?

Get a cheap sim free smartphone on ebay or something if you can afford it

  • 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?
  • Should I take my Iphone 4S abroad? Hi I'm going on a school trip to the Ardeche in France for 6 days, the only problem is that we have to sit through a 20+ hour coach journey to get there, I'm debating on whether to take my iPhone 4s with me because it is the only thing that would keep me entertained throughout the journey.
