Hi where can i buy a used mobile/cellphone here in busan?
I hope this information , can help you ^^
Not sure about the areas you mentioned but there used to be several shops selling used phones in the Seomyeon underground shopping mall. I haven't taken a walk there for about 18months, so may not be there anymore.
Or if you check the classifieds on this site people are selling their phones all the time.
