Twice as fast, and half the price
First of all no discount or coupon was offered for me to post this. As a background I have rented from two other services other than JWB (globaladvancedcomm [GAC], and one other company where the device never arrived), both were about twice the price. GAC was very expensive, and it was throttled very often. JWB, was the opposite. It was fast (I had the platinum plus), and I never reached the limit. It’s reception was great throughout Tokyo, wherever I went, and it lasted most of the day on a single charge. I am definitely using their service again.

5 Star to Japan Wifi Buddy!
First time customer and will definitely be a returning customer after this. Had a great experience renting the Wifi router from Tre. He answered ALL my questions promptly prior to my renting the device online. Couldn't be easier. My pocket wifi was waiting for me at the KIX post office when I flew in, picked it up and got it up and running in a few minutes. By the time I was on the Nankai Rapit heading into Osaka, I was totally connected. I did notice it took a good 5 minutes to really connect well but after that, it was all good. The only place with limitations were in the upper floors & basements of buildings but a good strong and fast signal otherwise. It made for communicating with people via LINE, WhatsApp and checking out FB and IG very easy. Great for looking up Maps and other places when you're traveling. I've recommended JapanWifiBuddy to all my friends who will be going to Japan. I also had no issues using it in the various Kansai region. Thanks Tre for making it so easy to have internet access in Japan!
