This trip involved layovers in Hong Kong and Dubai, and the internet connection at the airports was consistently smooth. Upon arrival in Mauritius, before applying for a local eSIM, I was able to use LINE smoothly with this eSIM. It was also fortunate that I had purchased this eSIM beforehand, as my return flight was canceled due to the US-Israeli airstrikes on Iran, forcing me to reroute via Malaysia and Hong Kong back to Taiwan. This eSIM proved useful at the Malaysian airport. Although I only used this eSIM at airports in these few countries, the internet connection was consistently smooth when watching YouTube, Netflix, and using LINE (text messages and calls), with no issues with intermittent call quality.
The connection was quite smooth and good. It doesn't work with just one phone; you need a Wi-Fi connection and the code to be read. I was able to take a picture of the QR code with another phone and read it, but it would be even more convenient if I could read it by pressing and holding the code.
