I never had to use the backup battery and it worked all day, every day, wherever we went. Would definitely use this again.

Nuestro viaje a Japón habría sido un fracaso de no haber contado con este pequeño pero utilísimo wifi pocket

Easy to pick up and connect to multiple mobile phones, very efficient and useful to get internet in Japan, also easy to drop off in a mail box before leaving Japan.

I highly recommend the support of this device to anyone traveling as a couple because it is simple and efficient. I also recommend shipping to your first hotel.

Great service, easy to use, very simple return, and pretty good battery life to boot.

Easy to order, affordable , fast delivery to our hotel ,quick return at the airport. Highly recommended. Will use again!

I highly recommend this company! Spent a week in Tokyo without any issues!

It's very practical wifi service, internet in every place, battery last long enough, the internet speed is really good and the prices is good. I Recommend this wifi for travel through japan.

We used the wifi for our 2.5 week trip. It was light weight and the battery lasted all day. For 3 people it was definitely more economical to use this vs. having 3 international wireless plans. The only downfall is having to stick together. We were able to make phone calls and send texts to the US.

We picked up the WiFi at Narita JAL ABC counter. IT was working within minutes.
Our stops in japan we're Tokio, Hakone/Gora, Kyoto, Osaka, Nara, Himeji and Hiroshima/Miajima.
We Had WiFi everywhere and never connection problems.
At the end WE simply but IT in the given envelope and a postbox at Narita.
We usually we're out more than 12 hours. Never had to use the powerbank for the WiFi.
Next time I will travel top Japan, I will book it again.
