Tips
– All SIM cards here use the same network, which is NTT DOCOMO. Therefore, in terms of coverage, all are the same.
– The download speed is usually maximum 150Mbps. When the service offers better or lower speed than this average, it is stated in the Note column.
– The speed is “theoretical”, and in reality it can be much slower. The speed also depends on the device and location.
– If you’re looking for a SIM card that allows voice call, take a look at PAYG SIM from b-mobile. Currently, this is the only card that comes with voice. (2016.03.03 See our new post for updated info. Prepaid Data and Voice SIM Cards Sold in NARITA Airport)
– It is usually cheaper to buy a prepaid SIM card in Japan. There are companies abroad that are offering SIM card to be used in Japan but they are usually more expensive than the same quality SIM card sold in Japan.
– Before purchasing, check the compatibility of your device. You cannot get a refund even if the device was not compatible.
– To find out whether the device is compatible or not, check the specification of the model and see if it is able to connect to one of the following bands. Also, the device must be unlocked.

– If you’re not experienced with setting up a new SIM on a device, finding a rental SIM card service that offers a refund could be a safe option. Check out our post Compare SIM Card Rental Services for Tourists in Japan
