For K-pop fans, shopping for merch is a highlight of any trip to Seoul. The most popular spots are Myeongdong and Hongdae. In the Myeongdong Underground Shopping Center, you'll find numerous shops packed with idol albums and rare goods. For official albums that count toward music charts, 'Kyobo Hottracks' in Gwanghwamun is a highly reliable choice. If you're a fan of a specific agency, visiting their flagship stores in areas like Seongsu or Gangnam is also a great idea. 

✅ Many of these shopping gems are hidden in small alleys, so you'll need real-time maps to find your way efficiently. To avoid getting lost in busy Seoul or to instantly upload your haul to social media, using an eSIM for Korea is a great option. It allows you to activate data immediately without swapping physical SIM cards, making your shopping trip much smoother. CHINGU Mobile offers various data plans for tourists and residents alike, so be sure to check them out before you head out.
