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

Excellent SIM card! I installed it on my phone ahead of time, and upon arrival, it immediately found a network and connected. It worked without any interruptions or speed drops the entire time.

The room was clean and the bedding was comfortable, allowing for a good night's sleep. The staff were friendly and helpful, making for a pleasant stay. The location was also convenient for sightseeing and getting around. The breakfast was varied and delicious, making it an overall satisfactory stay. This is a hotel I would love to visit again.

I used it in Osaka, and it worked almost perfectly, but the subway would slow down sometimes. Does anyone know of anyone who lives in the mountains? I stayed there for a day, and it didn't work that well that time either. But overall, it worked well! Highly recommended!!! I'll be using it again when I travel next month.
