Very useful
It was very useful. Good connectin in Osaka. However we could not put the persel through a letter box to return. Maybe we had to be more careful when we packed. Luckly post office was open.

Overall good, but not perfect
The Wi-Fi buddy was great to have, but there were several times it did not work or needed to be rebooted. Even in major cities, there were times it simply had no service, which we relied on. When it worked, it was great, but when it didn't work, it was extremely frustrating.

Wifi Buddy was The Best
We rented Wifi Buddy for our 11 day trip and it was perfect. Sometimes better reception than the ryokan we stayed in. Even excellent reception at Koyasan and Gora. It was a lifesaver for navigating Tokyo and Kyoto. Would totally rent Wifi Buddy again. No hassle. Everything organized. Good value. In other words, absolutely perfect.

AMAZING
I had an incredible time in Japan all thanks to JWB; I got their Diamond package and for what other companies like Global Advanced Communications offered for the same amount of data or at the same price, I think JWB exceeded my expectations. Their customer service online is great, picking it up and returning was super easy, and of course the wifi was fast with 4 people always using it for seven days straight.

Specifications
  • Requires a SIM Unlocked device with esim capability. If your device is locked, please contact your carrier to unlock it.
  • We include thorough instructions, via email, through our website and with customer service.
  • These are data-only SIM Cards. Carrier-based voice calls and text messaging are NOT supported. However, data-based messaging and telephony solutions such as Skype, Facetime, Whatsapp, Line etc. are supported.
  • To avoid provider validation complications, in some cases when users order far ahead of their actual trip, we will send a confirmation email, with a separate QR code later on, closer to the departure date.
