I first looked up the locations of the WowPass machines in Japan before heading there as soon as I left the airport. There was a huge line. You can put in Japanese bills and charge them as Korean won, but the exchange rate was terrible. I think I put in 10,000 yen and got 90,000 won? Anyway, it seemed like they rounded down the decimal places, so I really lost money. The currency exchange in Myeongdong wasn't crowded, so if you exchange your money for Korean won there and then charge your card, you won't have any problems!

Reviews: Jeju UNESCO Original Day Tour - East Course

Haley has been so friendly, helpful and sharing a lot of information about Jeju and its history. She offers her help to take photos for the tour participants especially the solo travellers. Even though most of the cherry blossom hasn't really bloomed yet in Jeju, she managed to find one along the stretch of road at Noksan-ro. She has made the tour a pleasant and enjoyable one.

I used this eSIM during my recent trip to Hong Kong, and the overall experience was excellent. Activation was very fast; I was online within minutes of scanning, which was very convenient as I didn't need to change SIM cards. Everything went smoothly; navigation and information searching were both very efficient. I will definitely repurchase it next time I travel abroad.
