Excellent
Everything was so simple. It worked great everywhere. Highly recommend this company. Since my new iphone 8 did not connect I had to rely on wifi so it was a neccecity.

Works as advertised and reliable
I can't recommend this service enough. It was amazing having access to Internet anywhere in Japan. I went to Tokyo, Yokohoma, Osaka, Kyoto, and Hiroshima and there wasn't a time when my wifi buddy didn't work. Would recommend to anyone going to Japan.

Travel Necessity
The WifiBuddy was a handy tool for my trip to Japan. The communication between the staff was sublime and made the purchasing process easy -- especially when they helped us locate the nearest post office to collect it from as we were staying in an AirBnB. During my month stay in Japan I had zero issues with the device, and would gladly use them again. The device was cheap for the usage we got out of it, the speeds were terrific, the reception was perfect everywhere we went, the battery life was good and the extras included (such as an additional battery, return postage envelope) were much appreciated. I would recommend this company to anyone travelling to Japan.

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.
