The SIM worked fine always, my friend used the pocket wifi but the battery charge ends after 10/11 hours. So I find the SIM more comfortable.

The stars are not 5 only because they sent me the wrong SIM, 8 days instead of 15, but Japan Wireless staff fixed the problem sending me another in a day and a half.

Sim Card pickup was pretty easy to find thanks to good instructions. I received personal envelope with nice welcoming message. Installation in the middle of busy airport took a few minutes and I was well on my way to enjoy Japan. Recommend!

The SIM card is fully compatible with my Canadian TELUS Samsung Galaxy S10 phone. I went from east to west Japan and had great signal the whole time. Download and upload speeds were fast. I have no issue at all and am very pleased with the service.

Expensive but very useful and perfect working.
Sim are a lot better than wifi because they can be used to call by Voip.

We had a 15 day sim card delivered to our hotel in Osaka. Very convenient and it worked perfectly during our trip around Japan, also outside the main cities. Recommend!

I did use a prepaid SIM data card from Japan Wireless it is the best option to be communicated in Japan

Will use again when I return to Japan. Made my visit so much easier!

Good coverage and good service. Everything perfect!

Super easy, Sim-cards were waiting at the hotel when I arrived.

It was really helpful to have a sim card with the Internet during traveling. Good quality and connection. Thanks!
