I cannot reach phone numbers in South Korea with my cell phone. 방금 전 한국 저작권 협회에 저의 핸드폰과 제 동생 핸드폰으로 전화를 걸었는데 연결이 되지 않았습니다.

I cannot reach phone numbers in South Korea with my cell phone. It makes an appeal failure. However, I have a plan that allows you to call to South Korea for free. The phone number is for Korea Music Copyright Association. Even with my brother's cell phone, I cannot reach any phone numbers in South Korea.
