Brilliant Service and Operation
I wasn't sure whether to rent a pocket wifi or buy one but after reading positive reviews about Japan wifi buddy and unlimited download for a reasonable price I thought I'd give it a try. What a good decision. From the delivery and pick up from my hotel, to the quality of the equipment and ease of use and connectivity throughout Japan travel, it was marvellous. The speed was great being over 100 MBPS wherever I was located. It enabled me to use the wifi connection to my phone for map navigation anywhere and this was a godsend which took all the stress out of navigating the streets of Tokyo and Kyoto and urban places like Yudanaka. We never got lost once! ...and the time it saved was a real bonus. The return procedure couldnt be more simple in the prepaid package which we left at our hotel reception. Certainly be using again in future trips and thoroughly recommended.
