To be able to use our SIM card, your device must meet the following conditions:
- It is a SIM-free device (Unlocked Device).
- It can receive Docomo signals. In most cases, band 1 and band 19 frequencies are used.
Band 1 (2100MHz) ：Most cities
Band 19 (800MHz) ：Rural areas, mountains, lakes, islands, suburbs of Kyoto, Nara, Hokkaido except for Sapporo, North of Okinawa, and Takayama.
Your device MUST support Band 1 to have signals for most of the time.
Band 19 support is not necessary, but it will be better if your phone device does.
You can check the Compatibility page to see if your device is compatible or not.
If your phone is not on the list, and you are unsure about the supported bands, please contact us with the device name and model number, as well as the specific location where you plan to use the SIM card. We will do some research and get back to you with more details.
