The best pre holiday purchase we could have made
We were in Tokyo for a week in May 2019 and ordered the Diamond WifiBuddy for our time there. It was fantastic from start to finish. When we arrived at the airport it was exactly where described, we had signal almost everywhere we went and the portable charger that came with it was just a bonus. Excellent speeds too. Really helped us navigating and to enjoy our time there even more. I would not hesitate to get another on my next trip!
