Really easy to install and use! Highly recommend getting a couple of days ESIM so you instantly have data when arriving into South Korea!

I have an ARROWS W2 Plus, and last time I had trouble using another company's eSIM, so this time I bought this one because it was so cheap, and I thought I'd give it a try. As soon as I arrived at Busan airport, I just set the APN and it connected and worked incredibly stably! It was 10GB for 5 days, but if you don't play games or anything, the capacity and speed are more than enough; I ended up using only about 3GB in total. I'll definitely buy from here again next time.

Reviews: South Korea SKT 4G eSIM | Calls + SMS | 010 phone number | 24 hr billing | QR code

Since this was a solo trip, I anticipated that I wouldn't be able to put my smartphone down, so I chose a plan with unlimited data and a phone number for emergencies. During my stay, I didn't have to worry about data usage, and even when using NAVER's real-time follow feature while traveling, or using Instagram and AI, the connection speed was fine. It was very comfortable, costing less than 500 yen per day for data usage.

Reviews: South Korea 5G eSIM | Dual Network • All AI & TikTok | 1–30 Days | QR Code
Guest User2026-08-14
I initially thought a pocket Wi-Fi would be more cost-effective for family use, but it turns out putting eSIMs in each person's smartphone is much easier and less hassle. This time, I got 100GB per day, which is more than I could ever use up, and the speed never slowed down, so it was perfect. Since 24 hours equals one day, I was able to use it for 4 days even though it was a 4-night, 5-day trip.

Overall, the eSIM I purchased this time was a very good experience. The purchase process was simple and activation was convenient; after following the instructions, it was working normally very quickly. The network connection was stable, and the network speed was ideal. It handled everyday internet browsing, navigation, chatting, and work without any problems. It's especially convenient for travel, eliminating the need to change physical SIM cards and saving a lot of trouble. Customer service responded promptly and patiently assisted with any issues. Overall, the user experience was excellent, the price was reasonable, and I will definitely purchase it again for future travel needs.
