The main advantage of using Japan-wireless for eSIM service is that they have English tech support in the same time zone that can respond quickly. I found their support very helpful. I will definitely use them again for future visits.

I used both eSIMs and a hotspot from Japan Wireless. The equipment was delivered on time, and it worked throughout my trip to Japan. I highly recommend their services.

Perfect and reliable for travelling around Japan

Worked well. Good instructions. Easy return.

Loved having this on hand, experienced virtually no issues and wifi wherever I went!

Pick-up at Osaka KIX airport from 9am... and worked perfectly during 10 days, both for business connection and later sightseeing in Kyoto/Osaka. Very convenient with multi-devices and even during transportation (subway/bus/train). Battery lasts 24h w/o issue. Highly recommended.

Smooth and reliable service, easy to set-up and so far, between Tokyo, Kyoto, Osaka, Hiroshima and even Miyajima, I always had a good connection.

it's really easy to use and has broad coverage in Japan

Excellent eSIM perfectly working and easy to activate!

Japan Wireless worked perfectly. As a family of four travelling in Japan, it was indispensable. Can definitely recommend.
