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.

I used it in China and Sri Lanka. I downloaded it in China, but I couldn't use it properly. I got help from a Chinese guy in his 20s, and luckily I was able to connect just as I left the express train's Wi-Fi area. I think it's important to check if it works at the airport and when the airport Wi-Fi is cut off, but I think it was a good idea. I extended my trip, so I purchased it for a slightly longer period, so this was also good.
