These days, the price of 2400 MNP modem is about 80~90 thousand won. But I heard that the price of some modems is about 50~60 won. I don't know the exact price of them. But Before a few days, I went to Yong-San. I heard that the price of 2400 modem is about 50~60 thousand won and if I add 20 thousand won, I could buy MNP modem. Maybe if you want to know the exact information about it, you'd better ask people standing in front of the restuarant. (KAE-MA-JUNG-BO) I hope that my message is good for you. Bye.
