Pocket wifi
Was really impressed with this pocket wifi, just wish it was availiable in other countries as well as Japan. Was connected nearly all the time even on a coach going 80 mph and in the underground subway lines, it really did a great job of keeping me connected to organise with my friends when we decided to go our own ways around Tokyo. Would definetly get one again if I revisit Japan =)

Excellent Product
The Diamond Wifi Buddy was awesome. It worked through my entire trip in Japan, was easy enough to use and set up, and worked across all the cities and destinations we travelled, including regional areas. Battery life is excellent and you even get a spare external battery charge it. Easy pick up from the air port and return. 10/10 would use again.

Highly recommend
Worked everywhere I traveled in Japan. I was able to communicate with friends via WhatsApp for free while in airplane mode. Also able to access Netflix via google chrome so we could watch American tv. Showed up on time and was waiting at hotel for me upon check in. Return was easy as well. Highly recommend. Will use again during future visits.
