I used this for my trip to Japan. I always had great connection and plenty of satay to do video calls and send photos. Sometimes the data was better than the wifi at hotels I was staying in.

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.

Overall, the signal is very good. The only problem is that there's no signal inside shops, such as at Narita Airport; some areas have low signal, making it impossible to send messages or contact friends via LINE. At Don Quijote Shinjuku, some areas have poor signal, making it impossible to contact friends; you have to walk to the edge of the shop to get a signal.
