Reviews
spring in korea never disappoints!! so happy that i tried this esim vs wifi. it is because it is a space saver in bags and you are connected wherever you go. even when alone with your phone. signal is strong and makes me easy to navigate and tour around. it is a plus when you wanted to translate anything you need to speak their language or buy something. went to korea alone because of bts and use this esim throughout the stay even in the concert day. signal is stroooong!!
eSim works well in Jeju Island, Busan and Seoul!! 5g coverage throughout my trips for 15 days, no lagging issues etc. i would buy it again if i ever going to south korea for my next trip~~
I had a great experience using this eSIM in south korea for 8days. Activation was easy and quick, i got connections upon arrival. Will use this eSIM for my next trip to south korea in the future.
The e-sim card was very easy to install and use. I installed it just before the flight and turned it on upon arrival. I never experienced any lags or signal loss throughout the trip. I always feel connected even on a different country.
I had a great experience using this eSIM in South Korea. Activation was quick and hassle-free, and the internet worked immediately upon arrival. The signal was strong in Seoul and other areas, with fast data speed for navigation, messaging, and browsing. No need to change physical SIM cards. Definitely worth it and very convenient for travelers!
very reliable and easy to use! we used it everywhere atound Seoul, Gapyeong, and Goyang
All through out our trip, the data has good signal. Would definitely purchase this again once we go back to Korea! 🫰🏻🇰🇷
Went on a 17-day trip to South Korea: Jeju Island, Busan, Daegu, Gyeongju, and Seoul. The internet was pretty smooth in all these cities. I mostly used Naver navigation and to reply to messages. I connected to WiFi at the accommodation every night, and the data was more than enough! Will definitely buy again next time!
Easy, affordable and hassle free. I've been getting esim whenever I travel not just for myself but even for my family.
great, works throughout all of South Korea. I went to multiple cities including Jeju, Daegu, Gyeongju, Busan and Seoul. I'm using a Samsung phone with nil issues.
