The value was excellent. The price, performance, and ease of pickup/discarding at the beginning and end of the 15 day trip made this something to recommend to others.

The previous year, on my last visit, I had rented a portable wifi unit. It was fine, but using even a physical SIM was much easier. I didn't have to worry about losing the unit, or be burdened by carrying around what amounts to a second cellphone of size in my limited pocket space.

Using the SIM made casual outings much easier in comparison. Also, returning the rental portable wifi was more work than simply discarding at the end.

Service très pratique et rapide. Livraison et récupération de la carte sim en 24h. Réseau disponible sur une très grande partie du territoire.
Merci beaucoup !

Super recommended. Ordered sim online at night and was delivered by next morning to my hotel. Decente price too

Everything was fine.

Best thing we did, after looking at standard options we opted to a prepaid sim (unlimited data) and had it delivered to our hotel waiting for us. As soon as we connected with easy instructions we were on our way, speed and connectivity was fantastic. We will choose this again next time we return. Highly recommend.

Very good service in all the places ive visited! Really stable connections even in more rural áreas. Thank you!

We bought two 30-day sim cards and everything went smoothly. We picked them up at the airport in Kansai, Osaka. The setup was easy and they worked fine all the time. In some subway stations in Tokyo the coverage dropped a bit, but it could be normal, since you are in the subway and there are a lot of people.
From our point of view, it was an excellent choice for price and quality of service.

Extremely convenient, reliable service and the data speed was excellent. Would purchase again!

I always use Japan Wireless and I always will. Cheap, reliable and never any problems.

It worked just perfectly!
Reasonably priced.
