Easy to install. Convenient to use. Good signal. Works well even in many places. There is a link to check how much you have used. Recommended. No need to put in a SIM card, it's a hassle.

The network card provided by this adapter in Osaka demonstrated a very stable and fast signal, and was easy to install. It is also very reasonably priced.

The signal is unstable. After watching videos for a while each day, the signal becomes extremely slow, and even mobile payment functions become unusable.

The signal strength in Japan is decent. I used it in Tokyo this time and it went smoothly overall. I would buy it again next time I go. The price is also very reasonable.

This trip to Japan was my first time trying eSIM, and it was incredibly convenient! After purchasing it, I installed it with a single click, and once I was in Japan, I could access the internet by simply turning on roaming. The internet speed was lightning fast, and everything was smooth – whether I was looking up maps, checking in, or transferring photos – there was absolutely no lag. I will definitely buy it again next time I go to Japan.
