Iphone in other Countries?

Yep they do.. I live in korea and i bought my iphone 5 in canada but it works well here!!

check with your carrier

South Korea uses CDMA. So if your iPhone uses GSM (has a SIM card slot), it won't work

Yes it will. Here is a link that explains how and why .http://blog.thearrivalstore.com/life-in-korea/will-my-phone-work-in-korea/

It should, iphones are both gsm and cdma

I doubt they even have public cell phone service in a restrictive country like that
