I received this call from friend stationed in Korea also. It just showed the number but don't panic...it's all they have. Be happy that they chose to call you from a foreign land....maybe they need to speak to some in their own language...just kidding...anyhow...KOREA it is!!
I got a call from this number and I was like wtf. but then I listened to the voicemail and I realized it was my boyfriend calling me. sucks that I didn't pick up cause I was asleep.
