During the 4-day unlimited plan I used this time, the data speed was fast, stable, and comfortable. I was able to use it without any problems even in places where it was difficult to connect to the signal, such as on the subway. I also liked how easy it was to set up the eSIM and use it right away. It was very convenient because there was no need to go through the hassle of returning it after the validity period had expired.

It was easy to buy and convenient. I also liked that it was unlimited.

Used in the Tokyo metropolitan area. I was able to use it without any problems when going out, traveling by train, at shopping malls, etc. Maybe it was the structure of the building? There were some places where it was difficult to connect, but activation was easy and I am very satisfied.

I didn't really understand how to set it up, so I contacted them by email and they answered the phone and kindly explained it to me.
Normally, I would purchase a SIM card and use it, so I think I would be able to use it even after the 30-day usage period as long as I had some remaining balance, but this time it stopped after 7 days as per my contract.

No special settings required, just use it as an eSIM
I am very grateful that I can use it immediately.
