Picked the SIM card up at Narita airport, at the post office in the 4F. Tried the SIM on two different phones - Android Pixel 3a and iPhone 6. Worked on iPhone 6 without any settings adjustments. On Pixel 3a I had to add the settings described in the attached manual, then it also worked without any issues. Cheapest version of having internet for two weeks I found, would recommend.

No problems, easy to use, very happy

Best deal, easy to retrieve (airport or your hotel) high speed internet throughout Japan. Wonderful for watching Netflix on shinkensen or live video on the ski field. I recommand very highly !

Data seemed to be fast and signal was strong. This is the second time I've used Japan Wireless and if I ever manage to go back I'll use them again. Never had an issue with them.

Awesome data coverage, suited our needs. Just be aware that Japan still works a lot on phone (for enquiries & reservations for example), so sometimes useful to still have some calls included

Qualche piccola difficoltà iniziale per le impostazioni, ma poi nessun problema di utilizzo, velocità sempre adeguata, anche in treno e comodità di non dover portare nient'altro con se o dispositivi da ricaricare... il costo non proprio economico, con i vari sconti e voucher mi è costata più di una delle schede disponibili al distributore del centro informazioni turisti (dove c'è anche più scelta, persino a Sapporo) :( la prossima volta la comprerò sul posto o al massimo ne ordinerò una dopo essere arrivato in Giappone.

Very convenient and friendly service.

Great service, fast delivery , good value for money and good clear communication.

Cheap and effective

It worked well with plenty of coverage
