Customer Reviews

Good service, good communication, easy setup and easy return.
Thoroughly recommended.

Easy to redeem and super convenient to use. Happy customer here!

Great coverage and fast service as always! Will never stop recommending this to family and friends.

Satisfied with the service. Sim card well delivered to the requested hotel address and right on time. Instructions took some time to figure out to activate the sim card. Maybe the instruction steps can be made more simple. Since this is for data/internet - could not do text message as my original simcard, but good enough to get connected.

Fast and very reliable at all times. Third time using this service and no problems.

convenient for foreigner who need to use WIFI service in Japan. I use in several part of Japan (from Ibaraki to Gifu and pass the other prefecture), it is a good response, long live battery.

Thank you again for another satisfactory rental!

It was very easy. I picked it up at the airport, turned it on, and I connected to the WIFI. It surely covered all the days I was in Japan. It saved me lots!

I'm using this service again when I come back this March for the Sakura season. Thank you CD JAPAN!

Everything worked like a charm! I am very happy with how easy renting and using the device was, also as warned the device I rented didn't always work when inside buildings, but when outside everything was a-okay

Great efficient service. Second time we have used and as reliable as ever.

Excellent product and worked well on our trip

Great service. SIM delivered on time and contains everything you need for quick set up. Return envelope is very convenient.

Super easy - wifi was waiting for us at our hotel and we dropped it off at the airport. No hassle, and it was super handy for our trip around Japan.

Great service, device worked very well and served our needs perfectly.

The device was delivered to the hotel (in Osaka) on time as requested. Returning it by dropping off at a post box at Haneda Airport was easy.
The device battery was good and most of the time, it could last for a day. Couple of time, we needed to use it with a power bank.
Regarding the wifi performance, we didn't see any issue while using in Osaka. But, in Kyoto, we did see connection dropped in higher ground (like top floor of Kyoto Station) and Arashiyama area.
In Toyko, several drops were experienced at subway.

Was very easy to pick-up. The first time around I used it, I didn't feel the internet was slow even after the 110MB limit a day (2016). However, this time there was a significant difference. I was prepared for it so it was OK.
It is still good value for money, especially since most other providers do not allow you to extend past 2 weeks.

It also worked on the Samsung Galaxy S6

Great service and easy to use!

I was really happy with the service. Good speed and not at all difficult to use. Sometimes I'd lose the signal indoors but not for long.

Great service for a great price!

Fantastic service..I did have a hiccup however when the service dropped out for most of a day,but I got a very quick response when I complained.

Very good service. good service, fast delivery of rental equipment

This was my 12th time in Japan, and I have always been very happy with the mobile wifi I rented from CDJapan. I have tried a few other brands over the years and some of them have been very disappointing. CDJapan has always worked fast and reliable.
The usage limits are clear and the speeds are as expected from 4G/LTE. I usually take their highest tier and it works flawlessly all day long, even for watching Netflix or other intensive usage. Highly recommend when going to Japan.

it was good as usual but sometimes very long to load.

Easy to use simcard. Just need to insert and follow the instructions given in the packet. Do be careful of the daily limit. The speed slows down quite abit after limit is reached.
Only thing to note is signal might not be very good if deep underground like in trains or basement of building.

Awesome ! I will use it everytime I'll go to Japan from now on !

I am very satisfied of having ordered this rental through you. The device arrived to my hotel on time and worked perfectly. It was very useful for me, specially to find directions and the connection was perfect everywhere. I really would recomend you to use this service!! Thank you very much and best regards.

very good on time service. router functions very well.

I am very satisfied with your service and the performance of the wifi router i got. I just found it hard to explain in English to the Post Office staff what I was picking up from the Post Office. I told them I am expecting a package from cdjapan. They asked for a parcel number. I could not give them any. One staff, who could understand English finally was able to help me and just looked for a parcel with my name on it. And sender was not even cdjapan. I got my router evenrually.

The ease and cost of the service were very good. The instructions for use and return were also very good. Having this as an option provided us the ability to use google maps for navigation which was vital to our time in Japan.

This is my third time using CDJapan Rental sim card and I am really satisfied with it. Your service really helped me a lot as it is quite hard to find prepaid sim cards in Japan.
