I was extremely concerned prior to my journey to Korea. This is my first solo travel, I don't speak Korean and I'm worried about the inconvenience of the translation software. I ordered a chingumobile sim card online, and upon arriving at Incheon Airport, I presented my passport to the staff and promptly obtained my phone card. It was truly convenient. I got in touch with the chingumobile staff, who spoke English fluently, and shortly after, I had access to the Internet.
