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.

It comes with an installation guide, works well, and has clear sound. It's suitable for international travel. 1 GB per day is sufficient for sightseeing.

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

Super easy to use, was able to connect straight off the plane. Stable connection throughout, I even travelled from Osaka to Kyoto and Nara, no problems at all. Sufficient data for 5-day trip, navigating and scrolling Instagram all day.

The SIM card works perfectly throughout Japan; it activated automatically upon arrival, no further action required. It picks up 5G almost everywhere, with speeds of around 100 Mbps.
