Differences from Free WiFi
It’s better to carry a WiFi router that gives you a stable connection anywhere.
You won’t have to find a WiFi hotspot each time you need one, so your possibilities are that much greater!
You may be frustrated with the lack of WiFi spots in Japan, their unstable connections, or being frequently required to register before using WiFi.
If you connect to unknown WiFi, it’s not always safe and could even threaten your device’s security through viruses or the theft of personal information.
