Great experience
The package was ready for pickup exactly where it was supposed to be at Narita. The SIM card worked great in my unlocked Galaxy S9+ in both the greater Tokyo area, and Sendai. Two 6-day cards were provided rather than a single 12-day card, and I had to change after 6 days - if I had not read the materials provided carefully, I might have missed that and had a problem.
