Excellent
I have no problem on the renting process and using the device. Rent process is simple and easy. The device is very good, it also came with a mobile battery which helps a lot if I'm using the device for a long time or if I don't have time to recharge the device the night before. Signal reception is flawless, it has good signal in Kansai and Tokyo area, and also in Nikko.

Worked like a charm!
Visited Japan for 11 days from Colordo... covered a lot of ground in Japan. The Silver package wifibuddy worked great all over the place. I just put it in my back pocket all day and never had a problem. Never even used the extra battery.

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.
