It worked at every place that I needed it to. Great wifi.

I always depend on this service when traveling to Japan. It’s reliable, essential, and the service is extremely convenient and great. The only thing I would mention is adding directions on how to pack in the envelope for return because the device can be too bulky to put through a mail slot (this is for when the post office is not open). Otherwise, I will use it again on my next visit when it happens.

Easy to reserve and delivered day before you need it. Returning is really easy too. I have access to wifi at my parent's house and normally use Japan Wireless when I travel within Japan. Having access to wifi always is a must when traveling since I use Google to get around. Comes with extra battery so don't need to worry if you're out all day.

Product was exactly as advertised. Price was good, delivery and drop off were simple. Just remember to bring the power bank with you as it lasts a solid 8-10 hours but we were out and about longer many of the days.

The portable wifi came to our house fast and even though the signal in the house is weak for cellphone, the portable wifi worked fine. The whole process is hassle free -- from ordering to returning. Over all it was worth it

The process was very simple. The device was delivered to my hotel upon my arrival and was easy to set up. The Wi-Fi worked great the entire trip. The return envelope was easy and quick. Thank you for a great experience!
