The first thing you must have in Korea for your vacation is Network Roaming. Let's say if you have Verizon Wireless, Sprint Nextel or AT&T as your default network while you're living in the States, you might be changed into the other network provider when you travel to the other countries. There are three network providers in Korea: SK Telecom, KT (Formerly known as Korea Telecom) and LG Telecom. First of all, I will introduce one of the famous network providers in Korean Republic, the SK Telecom.
