Japan SIM card compatible devices
Using this Japan SIM card will require an unlocked GSM cell phone with the necessary network frequency bands listed in the table above. If your U.S. or Canadian GSM cell phone is currently locked to a carrier like AT&T, T-Mobile or Rogers, you should be able to contact them and request an unlock code. There are also third-party services, for example at your local mall, that will unlock your phone for you for a small one-time fee.
Please refer to the list of cell phones compatible with OneSimCard. Most unlocked GSM cell phones are compatible with international SIM cards from OneSimCard. If you do not currently have a compatible GSM unlocked cell phone for Japan, you can rent or purchase one from us.
Note: You will need an unlocked international cell phone even if you decide to purchase a local Japan SIM card from elsewhere upon arrival in Japan. In contrast to that, with Japan SIM card solution from OneSimCard you will be ready to make and receive calls before you arrive in Japan.
Japan SIM card activation
Activating your Japan SIM card is as simple as clicking a button in your online account. Activation can be done from anywhere using Internet.
Installing your Japan SIM card is the same as any other GSM sim card, please refer to your cellular device's manual for details.
