First time in Japan
Loved being able to connect anywhere. No problems anywhere in Tokyo even in the train station.

Amazing customer service + Amazing wifi
I honestly can't think of a single flaw. The customer service was quick and kind and the pocket wifi was lightning fast and reliable my entire trip

Decent pocket wifi
We chose to go with the Diamond WifiBuddy since it was a good price compared to competitors and offered wide coverage. Coverage was particular important as we were trekking out to Takamatsu and Kochi, which as far as I knew at the time, was country country-side. Luckily that was not the case - we had good coverage. We went during a very hot time (August) so yes indeed, the battery did not last the day. However WifiBuddy does warn you of this and very kindly provide a spare battery for this very reason. The only other provider I have tried did not provide a spare battery (although if this was because we were not travelling during a hot time, I am not sure). The only con is that the connection would drop out randomly, even if we had only left our accommodation 10 minutes to an hour ago. It's a quick fix most of the time, going into the WiFi settings in your phone, but otherwise it was just annoying. Thankfully it did not occur everyday, although I honestly do not know what caused it. The WifiBuddy team kept in contact with me, advising that the device would arrive at our hotel a few days prior to our arrival. Would I go with WifiBuddy again? Definitely. I am not sure how the connection would hold up at Minoo Falls, since the first provider we went with was spotty for that area - I didn't go there this time. That would be the only sort of "testing" I would review over next come to see more of Japan. Thanks WifiBuddy for the solid & economical service.

Perfect
It Was waiting for me at my hotel, and I just gave it back to the hotel to mail in the envelope they provided. Easy to use. Pricing reasonable. What more could you ask for?

It made the trip easier
Absolutely found this little pocket WIFI a god send. Made our trip so much easier to translate through language barriers, navigate to places of interest and find out which transport was required. Worked absolutely everywhere we went and was a seamless pick up and drop off. Great experience and simply cannot recommend this company enough.
