Albania

I used it in Brunei for 5 days. The speed was perfectly fine. The setup and activation process was smooth, and I could always see my remaining data allowance, so I could use it with peace of mind.

Very efficient and easy to install. Good coverage in Estonia. No problem at all, very good value for money!

The network communication is excellent, and there are no problems using Google navigation smoothly.

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.

I don't blame the UK underground for not receiving a signal, as it seems to work fine with anything. At other times, it should receive a signal, and most importantly, it works in multiple European countries. Since we'll be watching Netflix and YouTube in the hotel every night, we need to subscribe to unlimited internet, as we're worried about the hotel's Wi-Fi being unreliable.
