Worked great
Only thing that confused me was I was picking up the sim cards from a post office at the airport, not a Japan wifi buddy office. Instructions to set up for android were slightly different than how my Google pixel actually worked, but it was still super easy. The data was always super fast and I used it a lot. Would buy a sim card here again.

Worked exactly as anticipated
I have no criticism. The sim cards were delivered to the airport post office as expected and the sim cards themselves performed to spec. Would buy again.
