100% Great service would use again and recommend
Pick up at Narita airport from the post office was very easy. Everything is exactly as described from the company. The package came with instructions for settings and installation. As an non-Japanese speaker this SIM card was my lifeline!

All good
Worked fine as secondary card in a OnePlus 6T. I could make calls with my regular card and use data with my Japan WifiBuddy cards. Each card is only valid for 6 days, so I received a stack of them, replacing them every 6th day.
