Data SIM worked like a charm, delivery was spot on. Reasonable price, I would definitely use this service again.

Connection is good and stable.

Had a 10-day trip in Japan so me and my girlfriend decided on a 15-day internet SIM card. I put it in my extra sim-slot, did the settings and restarted the phone. Voila! It worked at once!
During our trip we had more than good enough internet to share. We're just at a few points while riding the train that it got a bit slow. But in the cities it was more than enough.
We had usually a solid 4G+ connection that went fine for all uses needed.

Just perfect. The sim was easy to install and No problem with the connectivity. It worked smoothly with a decent speed (almost 100 Mbps) in most of the places in Japan. Would definitely recommend this one.

100% recommend the 15 day SIMs. We got 4, one for each of the family, and worked perfectly everywhere we went, even in remote places. Made navigating, keeping in touch, finding shops and restaurants and public transport so much easier. Picked up at airport and plugged in and off we went. Thanks for the terrific service.

Perfect travel companion in Japan. Just insert on your phone, simple configuration and all good to go!!!

I had some troubles at the airport finding the delivery point, but aside from that the internet was stable, easy to install and worked perfectly. I will definitely use this service on my next trip to Japan.

Ottima copertura ovunque

Japan Wireless service was excellent and we didn't get any drops or blackouts. Service was constant and we are very satisfied with Japan Wireless Service.

I would recommend this to anyone looking for a short term data only service in Japan.

They don't have a pick up location in Haneda Airport however they did send the SIMs to our hotel in Shinjuku and it arrived before we landed in Japan.

Very good, easy to order and efficient. Just what you would expect for be service in Japan. 🙂

Great speed and coverage at a very low price. Will order again when in Japan.
