Nabin,
This is a site for Best Buy customers, and we support sales of retailers who invite us into discuss our products with their customers. In this case, Best Buy is hosting the forum so we hope that you'll consider them with your purchase options.
Best Buy is an authorized dealer of Samsung cell phones, and sells brand new mobile phones at reasonable costs and even provides services with creating accounts and shopping for accessories.
Information on outlets in Korea is not something we can provide. Please consider purchasing from an Authorized Samsung dealer in any country you're considering our products.
Thanks for your interest in Samsung products.
--Mr. Samsung
