Customer review

4.93/5

Daniel K Kikumoto

Easy to connect and very reliable. The portable charger was also handy for my iPhone.

Pavel Karpushin

worked perfectly in Japan, main island and Hokkaido, even on the plane during the flight

Federica Pinna

Ho noleggiato un wifi tascabile per 2 settimane a Tokyo. 1. Ottima comunicazione in fase di acquisto e anche prima di ritirare il wifi tascabile in aeroporto. 2. Wifi tascabile molto efficiente ovunque. 3. Restituzione del prodotto molto semplice: basta rimettere il tutto nella busta ricevuta a questo scopo e di depositarla in qualsiasi cassetta postale in aeroporto. 4. 48 ore dopo aver restituito il router, ho ricevuto conferma che tutto era in ordine. Consigliato!

John Charles Ferguson

We have used Japan Wireless 4 times now. Can always count on it!

Ray Jay Wherley

This was the second I used their service. The router worked like it should have, I had wifi service every where I went. Pick up and return were both easy and hassle free.

Jennifer Krohn

Japan Wireless makes it easy to pick up and drop off their hotspots. We never even needed to use the battery because it stayed charged all day. We would use them again!

Keith H. Goya

This product was easy to use and it was easy to carry around. It came in handy for keeping in touch with my family.

Ricardo Esteban Figueroa

Great device love it

Christopher Taylor

Travelled from Aus, stayed in Japan for 17 days, excellent coverage from pocket wifi, easy collection and return process, cant fault it. Would definitely use again.

Andrew Kitchen

Perfect. Faultless service.

Christina Esquivel

I don’t make reviews but this poker wifi really made our Japan trip the best experience as first timers. It was recommended to me and I will now always recommend it.

Arun Ramanathan

I travelled to Tokyo, Osaka, Kyoto and the surrounding places and had service all the time. It really made the trip so much easier. I highly recommend it

John W Milani

Everything worked smoothly and efficiently!

Matthew Sandford

Very easy set up and has worked perfectly every where I’ve travelled in Japan

Darrin Kaya

I had the wifi sent to my hotel and it arrived as scheduled. Only issue was the charger cord, but I had some extra cords for my phone so I wasn't an issue. Will rent again!

Manuel Murayama

Great service and very easy to use

Richard Young

Have used Japan Wireless for 5 of our trips to Japan. Reliable delivery and response if a problem. Would like a product that might be lighter in weight and the charge longer. We had that type of product (smaller too) in Korea. a suggestion to look into upgrading your product. thank you

Lynell Miyao

Rented 4 for our family of 11 trip and no one had problems with connections. Japan Wireless made it easy to pick up from the Post Office as well as dropping off in a post office box. Thank You

Cynthia Nishihira

Great coverage with Japan Wireless. I do wish the battery life lasted longer for the device - but I'm glad that I was provided the additional portable battery once the device started to drain. Overall - I love that I was able to have the device ready for me at my Hotel and I was provided a self addressed envelope to have mailed back on way out of the country. I have tried using eSims in the past (but for some reason - once I return to the US, I end up having issues switching back to my regular service). The mobile wifi is still the best option for me and I think Japan Wireless does a great job at providing stable wifi.

Gabriel Case

My phone isn't unlocked so I wasn't able to use an eSIM or physical SIM during my visit, so this pocket wifi worked great. I always had good connection and the battery lasted quite long! Overall a great option for the price/if you have multiple devices!
