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!

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.

Perfect for people coming to China. Easy to use, convenient, connects to the internet and works fine, not too slow.

Once you get used to eSIM, you can set up the connection quickly, and if you contact customer support before departure to confirm that it's properly installed, you'll get a quick response. While the signal was sometimes a little weak in certain areas, it generally works without any problems. It's also inexpensive. I recommend it! 😊

I use it for navigation so I don't get lost. I can't say it's bad in that respect, but I can't say it's too good either, okay? (Mom sighs)
