Installation is just one tap, and once you arrive in South Korea and switch to it, you can start using it immediately. It's incredibly fast; I heavily use NAVER Maps, but I've never had any problems with it not opening or anything like that. I highly recommend it to everyone!

I booked through Casa le Sim and used it for my entire stay in Seoul, and I must say it always worked, even on the island. Highly recommended.

I downloaded the app at home and then used roaming after arriving at the airport in Korea. It activated smoothly, and I was able to use it just as comfortably as when I was in Japan. I was on a 2-night, 3-day trip, but since it was a 24-hour plan, I only needed a 2-day contract. I thought this was better than a plan that charges per day. Most hotels and restaurants have Wi-Fi, so I chose 3G this time, but 1GB per day would probably be sufficient. Even with constant map searches and constant conversations with the AI, I never exceeded my data limit and experienced slow speeds.

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.

A beautiful tradition! The hanbok selection was amazing and the staff were nice, they help you dress up and do your hair. Wearing a hanbok gained you free entry to the Gyeongbukgong Palace also, which was great. Bag is included, but you have to pay extra for petticoat (~2000 won) and other additions but I would recommend!
