How to get my iphone 5 work in Czech Republic?

So I'm going on a trip to Czech Republic in a couple weeks and I really want my phone to work. Texting and calling I'm not so concerned with but I really want to use my twitter and instagram while I'm there. My carrier is Verizon and their prices are way too high for only a few MBs. I'm thinking about getting a nano sim card but the problem is I'm staying in a small town called Loucovice in the mountains and my mother is concerned with it working or not, and the house I'm staying at does not have Wi-Fi. At this point I don't know what to do but I really need my phone to work and if anyone has any advice that'd be great thanks.

You can get your iPhone factory unlocked if it's not unlocked already. Buy a nano prepaid SIM when you reach Czech. Put it in and you're good to go. Check online if you want to factory unlock your iPhone 5.
