★★★★★ The setup was very easy, and I was able to use the internet immediately upon arrival. Using sightseeing and restaurant searches, as well as map apps, was very convenient. I had no complaints about the communication environment during my trip and am extremely satisfied.

I used it on a business trip. While many things are affected by the weak yen and rising prices, eSIMs seem to be going against the trend. I think it's a great value product. I was able to fully utilize it from the moment I arrived on the plane until just before takeoff. With the increasing number of systems that allow booking and payment via apps and smartphones, it's become an indispensable tool.

Excellent e-SIM, flew to Japan, the network is stable and fast, sometimes even faster than the hotel Wi-Fi. The price is unbeatable. I recommend it!

The connection was good, and since I installed it in advance, I was able to use it immediately upon arriving in Guam. I was assigned a local number, so I was able to make calls conveniently while there.
