Fantastic and easy to use. eSim red is with SKT, which is a top provider. I've used the eSim red 4 times now, and it has worked every single time. Airlo does not work well in Korea and is horrible. 

It was the first time I used the airport pick-up method. I arrived in Korea very late and there was still a dedicated person at the counter. The service was very fast.

After picking up the barcode at Incheon Airport, the scan was successful immediately. It was completed faster than expected. I am very satisfied!

Their price and service are really competitive and delivery speed is also fast as well

keep in mind that you need to register the sim with your id in order to use a phone # which can be used as an ID in South Korea within 30 days, but it won't begin actual usage period until you actually start using it in South Korea

在仁川機場可以快速的找到櫃檯，領取也很方便。 只是因為是現場拿到，無法提前準備，當天在機場一直失敗，設定了快15分鐘才成功，需要有點耐心 除了一開始的小挫折外，目前使用到現在都很滿意，也真的有用到電話號碼去進行候位，方便又快速！

能有韓國電話號碼,方便餐廳訂位,網路尚屬順暢，換SIM卡即可立即使用,吃到飽不必擔心使用過量,CP值高

很推薦來韓國要有號碼，以備不時之需，讓她人可以聯繫你，美中不足就是不能打出去🥺🥺

空港に着いてすぐになんの問題もなく使えました。 使用方法のスクリーンショットをとっておくと便利です。

大部分時候都很穩定 人多的地方稍微卡一點而已
