I have a US Verizon account but I'm studying abroad?

Essentially what I have is an upgrade coming in August and what I'm trying to find out is if I can use that upgrade in Denmark where I will be studying. Will I be able to walk into a Verizon store and get one even though my account originates from the US. I know Verizon is unique with their Sim Cards, I plan to be getting a Iphone 6 so could I get Danish Sim card there and switch it when I get back. Any advice or alternative suggestions?

I have a water damaged iPhone 5s that I'm wanting to recover the picture from. They are not backed up to iCloud because I ran out of storage on there. I have backed up my phone to my mac recently, but the photos i'm most concerned about were taken after that back up. Is there any way that I can recover my photos?
