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.

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.

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!

At the start the "frequently observed error" about the profile occured, which made it necessary to reinstall the profile according to the instructions provided. After this, the E-SIM worked perfectly during my 14 day stay in Japan.

Have been using Genki twice. As they use docomo the receiving is very good everywhere we travel in Japan. It would be yet better if we do not need to return the sim card after use.

With Genki Mobile everything went as smoothly as it could go. However, I would steer clear from the 1G/day Aterm hardware that I used. The previous year in Japan, I used a different company/ device and did not experience spotty wi-fi as I did this time and the previous device would keep a charge all day where the Aterm did not hold it's charge for the entire day.

The service from the Genki Mobile team was amazing. We travelled from UK to Tokyo and I placed my order in the evening and it was ready for collection the next morning. The internet speed was great, the connection was spot on, the accessories like the portable charger just made it that extra bit better. Perfect for google maps, instagram, web surfing and everything else including downloading things. We got the 7gb package and it was worth every penny I mean YEN! I strongly recommend! Thanks again!

Friends had recommended Genki Mobile as a must have for our family adventure to Japan this year. Usually, the process of finding the right provider, the right option at a price you can trust is tedious and afterwards you have that 'should have used a different provider'.Not with Genki Mobile.1. Price: We paid with paypal online 10/10 easy and value for money2. Collection: We collected it at the hotel reception when we arrived (could have been at the airport but coming in late we requested to post it to the hotel) 10/103. Battery life (teenagers sucking it dry all day) 10/10. never had to use the USB battery pack that comes with the package.4. Coverage. 10/10. even top of a mountain it worked.5. Return. 10.10. It comes in an envelope. You use the same envelope to return it. We dropped off the envelope at the post box in Lawson's in Osaka airport. Easy.We went for the pocket wifi option so all our phones could connect.When things work and work well it's important to say so.Pretty Cool!

Extremely simple process to get the pocket-wifi and return it. Able to get it same-day after the other service we tried to get pocket-wifi from fell through. Will absolutely go with Genki Mobile again the next time I return to Japan!

**Amazing customer service- I went to Japan over a month ago, and Genki Mobile was a life-saver for me. I had originally rented Pocket WiFi from another "popular company" and paid around $120 for the WiFi, but that company NEVER responded to two of my emails after I accidentally forgot to pick up my WiFi (I had emailed them asking if they could ship the WiFi over to my hotel, with me covering the additional charges). You will run into NONE of these headaches with Genki Mobile. Not to mention, my order with Genki Mobile cost around HALF the price. The in-person pickup is super convenient since it is easy to find Genki Mobile's office, and all the staff are so friendly. I also never ran out of WiFi every day. I used the WiFi to access Google Maps for whenever I traveled, and the WiFi never randomly disconnected. The WiFi itself works 100% accurately.

We rented portable wifi for a 9 day trip to Japan. The router came with a battery pack, which was super useful! No issues, glad we chose this company. Pickup at the airport was easy once the staff realized it was a Genki Mobile pickup, and returning through prepaid mail was a breeze.

When I moved to Tokyo, there's a 4 days gap between my move-in date and the WiFi installation date with NTT.Luckily, they have a campaign and they offered me a free pocket wifi that I can use until I have my wifi installed. From delivery to usage, everything is free. They even provide a letter pack envelope so you can return it conveniently.All services are english-friendly, and they even go the extra mile to help you with your concerns and solve issues together!I'm writing this review after 2 weeks of using their gold plan service. No downtime and amazing coverage! I'm in a 50+ sqm apartment connected to the 5G line and I don't suffer from any latency issues. Love it!

I was traveling far to get to Japan and was nervous about My SIM card and data but Genki mobile was ready and waiting for me in an easily accessible place at the airport. It was very simple to set up and gave me great service and support during my long three month stay. I was able to contact all my friends and family no matter where I was. And sight seeing was made easy with quick flowing data. I was very happy with my purchase and rental with Genki mobile and would definitely recommend it in the future. I was also quite happy with the price as it was quite cheap compared to other sellers.

We got Genki pocket wifi as a free service while our internet application is still on process. We got 1gb data per day as soon as we submitted the application. It was delivered to our house and returning it was easy as well as you can return it via mail or hand it yourself. set up was easy as well.

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.

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.

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.

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.

Excellent customer service, picked up at the airport. Wifi worked well at all times when using. 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.

Excellent customer service . They sent numerous emails to keep me informed. The portable unit was small and never let me down , even in the remote Kurokawa onsen area . We picked it up and dropped it off at the airport, even though we landed at midnight it was still waiting for us.£55 GBP is a lot of money for 2 weeks but in a country where we do not speak the language and we did a lot of travelling it was well worth the money .I recommend Genki Mobile .

Good bang for the buck. Previously I used Sakura but decided to give this service a shot since they use NTT Docomo. Only dropouts were in Yokohama during Pikachu parade but with the amount of people playing Pokemon Go it was kind of expected. Battery lasted almost all day even using my laptop on shinkansen to update my web store
