What is a SIM card? A SIM card is a small chip inserted in a smartphone that allows the device to get access to a mobile network. You can still use your phone overseas without swapping the SIM card, however, international roaming charges will be applied, which are not cheap. By changing the SIM card to the local mobile operator's, you can keep your device online economically.
What you need to use a CDJapan SIM card An unlocked smartphone that is compatible with 3G/LTE Band 1(2100MHz) and 19 (800MHz).
Unlocked devices mean they are not locked by a specific operator. If you buy devices directly from a particular operator, they are locked by the operator. Also, the devices that indicate a specific operator's name are most likely locked.
To use our SIM card with your phone, you will need to configure the APN(Access Point Name) setting. It does not work automatically. If you have an android device, you will create a new APN by entering the information we provide manually. If you have an iPhone or apple devices, you will download the profile using Safari browser and install the APN profile.
If you're going to use iPhone, please delete our APN profile once you have finished using our SIM card. If you don't delete it, your own SIM card outside Japan may not work properly.
For the details on how to set the APN, please check the following page: SIM Card APN Setting
If you are not sure if your phone is unlocked, or if you are not familiar with changing a SIM card, we recommend you rent a mobile wi-fi instead of a SIM card. Using a mobile wi-fi is very easy and it will work with any wi-fi enabled devices. (See our mobile wi-fi plans: Mobile Wi-Fi Rental)
How do I know if my smart phone is compatible?
Your device must be unlocked (check with your retailer if you are not sure) and must be able to connect to the networks that match our SIM card. The tested compatible devices are listed on the following page: Compatible Devices. Links to our blog explaining how to check the compatibility can be found on the same page.
Is it really unlimited?
Yes, our service allows you to have unlimited access to the Internet. However, the connection speed will be reduced to 200Kbps until 12am once the data traffic volume exceeds 110MB that day (220MB on the first day). After 12am, the counter is reset.
What can I do with 110MB a day?
You can do all of these within 110MB data. (Estimate)
- Surf the web：100 web pages
- Message app (LINE, Whatsapp, etc): 100 messages
- Email: 20 messages
- Facebook: View 100 updates on the news feed
110MB is not sufficient to watch Youtube(normal quality). You will finish high speed data if you watch a video for more than 20min.

How fast is the speed?
Theoretical maximum speed is 260Mbps. The actual speeds will vary and are not guaranteed.
None of the packages suit the period I need.
Please pick one from the packages that are available. If none of the packages suit the period you need, you can either extend the rental later or simply get a longer package and return it a little early. For example, if you need it for 8 days, you can buy 7 days package now and extend 1 day later, or buy 10 days package. Tips: Depending on the period you need, it could be cheaper to get a longer package. For example, if you need it for 9 days, it is cheaper to get the 10 days package than the 7 days+2 days extension. Please compare the prices and pick the best option for you. Check the extension rate on the following page: Extend Rental Period
I am going to visit different prefectures in Japan. Will I have the internet everywhere I go?
Our SIM card uses Docomo network, which is the best in terms of coverage among all mobile phone networks in Japan. However, it is up to your device whether it can make full use of it or not. If your device supports all of the following bands, you will have stable internet pretty much everywhere you go: 3G/LTE Band 1 (2100MHz), 3G/LTE Band 19 (800MHz), and LTE Band 21 (1500MHz).
Can I use messaging apps such as Whatsapp, LINE, and facebook messenger?
Yes. Your account will work even if you change the SIM card.(When you insert a new SIM card and start an app, you might be asked to "Change Number", but just ignore the message and proceed.) IMPORTANT: If you don't have an account yet, please create one before coming to Japan. Our SIM is data SIM, therefore you cannot create a new account with apps that require a phone number for verification.
Will tethering/hot spot work?
Yes and no. Our SIM card itself does not restrict tethering, however, with some devices it does not work even if the device itself supports tethering/hotspot feature. We don't have information on what works and don't, so if you are planning to use the feature, please be aware that there's a chance it may not work.
