Data truly unlimited, fast connection Tokyo, Kyoto, osaka
Data truly unlimited, very well connected in Tokyo!
How I used it -instagram, heavy WhatsApp including video calls
For new users - don't stress said it doesn't connect immediately after the flight landing , not mobile has network even japanese ones. It works right within the narita airport and connects super fast.
