Highly recommended
The whole process was very easy and simple. Picked up at the airport without a problem. Super fast internet pretty much wherever we were; even on the shinkansen! Returning it was really simple as well, they give you a return envelope. Never had a problem with the device, it just needed to be turned off and given a rest every now again due to the hot weather. The internet was never throttled at any point as well. Would definitely be using again when I return to Japan.

Awesome
Absolutely awesome service. Friendly contact to define all the needed informations. The wifi Buddy was delivered to our first hotel with a powerbank and an envelope to drop it off at the airport post office. There wasn't a single time that it wouldn't work or would run out of battery due to the additional loading with the powerbank :-). We will get it again once we come back to Japan! Thanks for the great service

Works as expected
It all went smooth, picked up the wifi at the airport, dropped it at the other airport. Could not have a better service.

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.
