Excellent service, reliable product
Great cost compared to some of the competition. Outstanding customer service. Excellent speeds across Japan. I used mine in Tokyo, Osaka, Kyoto, Nara, Ise and up in Koya. Always greats speeds and strong connection, including on the train moving between cities. Would highly recommend using this company/product. I will definitely use them again next time I travel to Japan.
