Trustindex verifies that the original source of the review is Google.Genki Mobile offers an outstanding experience all around! The setup is seamless, the wifi router is reliable and incredibly user-friendly, and their prices are very reasonable. Plus, their service quality is exceptional: I reached out to inquire about a specific router model I loved during my last trip to Japan, and they made it happen (delivering it to Narita Airport, T2). I wouldn't hesitate to use Genki Mobile again anytime!

Trustindex verifies that the original source of the review is Google.Genki Mobile is terrific. I have used them multiple times for mobile wifi and SIM cards while traveling in Japan. Their services are very easy to navigate on the website to select the right product needed. Pickup was very simple (at Haneda airport in my case) and return was even easier - just needed to drop the items in pre-addressed envelope into Japan Post receptacle at the airport on my way out. Whenever there was a question or clarification about my order, I received a personal email from their customer service department. I would definitely use them again, every time I get to travel in Japan. thank you!

Trustindex verifies that the original source of the review is Google.Great product, great service. I got a 1GB plan originally, and then upgraded to a different product with 7 GB per day. They were very easy to work with, and returning phone with envelope was easy.

Trustindex verifies that the original source of the review is Google.Excellent E2E communication by Genki team. No issue with the Pocket WiFi, easy to operate and come with easy to follow step-by-step instructions. But Pocket WiFi drain battery fairly quick. Thankfully it comes with a small battery bank. The only downside was the mobile coverage - quite a few spots difficult to get good signal level and at some spots no signal. Overall, I'm satisfied with service provided by Genki. Will definitely use them for my next Japan trip.

Trustindex verifies that the original source of the review is Google.Second time using this company for my trip to Japan. And it won’t be the last time! I absolutely loved using the portable wifi. I felt safe knowing I had wifi with me at all times. Easy to use when getting it. Very easy steps to activate it. And it’s a nice small device that can fit in any size bag or purse. The battery life on them are amazing. I be leaving my hotel at 8am and coming back to it at 9pm and I still have battery life to it. See you again Genkimobile in 2027!

recommendsTrustindex verifies that the original source of the review is Facebook.Pickup at Haneda International Terminal was easy. Using it was easy plus instructions were included if needed. Had full coverage across whole of Japan. Came with a portable battery bank if the device needed charging. Highly recommended. The only minor issue was dropoff. If you return it with everything inside the provided pouch, note that it will be too big in the middle to fit in the dropoff mail slot. If you separate the items from the pouch and spread it evenly in the dropoff envelope, you won't have any issues. Just keep that in mind.

recommendsTrustindex verifies that the original source of the review is Facebook.I chose Genki Mobile because I wanted to pick the device up at the International terminal at Haneda Airport and drop it off at Kansai airport. The pickup and drop off worked exactly the way they were supposed to. We used the mobile wi-fi for more than two weeks in Tokyo, Kyoto, Takayama, Hakone and Koyasan. The connection was excellent and at time it had 5 devices connected to it. It would not last the whole day on one charge; that was not a problem for us but others might like to use a battery booster.

recommendsTrustindex verifies that the original source of the review is Facebook.I used the SIM card for my 10 days in Hokkaido. The SIM card was sent to the hostel where I was staying and I was able to get it without any hassle upon check-in. SIM card worked beautifully throughout my whole journey in Hokkaido. Returning it was also a breeze. Just drop the prepaid docket at the Post Office and it’s done. Will most definitely use it again.

recommendsTrustindex verifies that the original source of the review is Facebook.Complete satisfaction; uninterrupted service without any glitches. I was in the far corners of Japan, outside cities, along the coast of Japan sea in Hokkaido, and it worked perfectly even there. The days I used the gps for the whole days, I had to recharge it once during the day but that was expected. I will only suggest having the data tracking part is a bit simpler, as the Aterm Mobile map might be difficult to navigate without knowing Japanese, but otherwise no complain about the service. I will recommend it to everyone, and will use it again on my next visit.

recommendsTrustindex verifies that the original source of the review is Facebook.Очень удобный вариант. На момент поиска один из самы дешевы и просты . Получила в аэропорту, вернула - кинув в почтовый ящик там же перед отлетом. Вайфай работал стабильно и на орошей скорости, трафик не экономила. Токио, Йокогама, Хиросима, Киото - полет нормальный. Посоветую - да. Воспользуюсь еще раз - да.

My daughter and I used while visiting my son and his family which helped to communicate with them when we were out on our own in your beautiful country. The return process was as easy as the pickup.
