I used this in KL, Bangkok and Shanghai. Overall the signal was ok. Sometimes we do get a drop out but it’s not often. We managed to use all social media platforms with this eSIM at Shanghai. Only thing is if you want to hail a ride you’ll need a number for it in china.

I always use it when I come back to Japan during my trip around the world. It's easy to connect to the internet, so I can use mobile payments like Mobile Suica and Rakuten Pay.

Everything started working immediately upon arrival in China. You can activate it in Russia so it works as soon as you land. It works without any issues in Japan and China. 1 GB per day was plenty.

My experience with eSIM during my trip to Seoul was excellent! The installation process was quick; simply scan a QR code to activate. Whether on the subway, using Naver Maps for navigation, or taking photos at Seongsu-dong, the connection was consistently stable and incredibly fast throughout Seoul. It completely eliminates the hassle of changing physical SIM cards or carrying a Wi-Fi device. Even in the crowded Myeongdong shopping district, there was no network outage or speed reduction, making it the top choice for connectivity while traveling in Korea!
