South Korea and mobile phone

I'm leaving in a few days to South Korea. I will bring a iPhone 5 and a iPhone 4. When I', in Hong Kong I use a pre paid phone card. I little bit confused if the sims from Korea can be used in my Dutch iPhone

Most importent is the internet so we can check the internet and navigate.

Sorry this is not a question about photography. But I send photo that I take with my 5D III with Eye Fi to my phone so I can place them on the net. Hope this count

You should be able to buy pre-paid 3G or 4G sim cards in South Korea (I'm almost certain you can).

Is your mobile phone locked by a mobile service provider in the Netherlands? Why I asked is, when our daughters comes to visit Laos, they bring their Australian locked mobile which works fine with Lao sim cards. Phones in the Netherlands may be different.
