I was able to use it comfortably, so I recommend it. I got the 100GB per day plan, but I only used LINE, maps, and store search, so I didn't actually use even 1GB per day (lol). It's also helpful that you can check your current usage. I'll use it again next time.

What Is eSIM Card?

An eSIM is a digital SIM card that allows you to get connected to the internet (sometimes with calls/texts). For example, WhatsApp works quite well with data-only eSIMs. You can freely do media sharing, calls, and messages!

Your phone number remains the same, and you can use it as usual. If you get a new phone number, turn off the regular SIM card then.

Usually, 4G eSIMs are enough (50-100 Mbps speed) for you to use with low-cost payment. But if your phone is 5G-compatible, then that will be better for higher speed.

You can pick up your tickets at Red Now Studio (9-8, 3-ga, Hoehyeon-dong, Jung-gu, Seoul). You can also purchase cable car and entrance tickets at the base of Namsan Tower, but there's a huge line, so it's better to use this voucher! Even so, I still had to wait about an hour to get on the cable car... If you're going to time it for sunset, I recommend giving yourself plenty of time!

Myeongdong is one of Seoul’s most vibrant shopping districts, offering a perfect blend of modern retail, street food, and energetic atmosphere. The streets are lined with cosmetic stores, fashion boutiques, and trendy cafés, attracting both locals and tourists. It’s especially lively in the evening, when vendors set up carts selling tteokbokki, hotteok, and skewered meats. The experience is exciting, though sometimes crowded, especially on weekends. Prices can vary, but there are plenty of affordable finds if you explore side alleys. Overall, Myeongdong is a must-visit for anyone seeking Korea’s youthful culture, food adventures, and memorable urban energy and charm throughout.
