To be able to use our monthly SIM card, your device must meet the following conditions:
- SIM-free device (Unlocked Device).

- Must be physical SIM card compatible (make sure your device has a SIM card tray).
- Capable of receiving Docomo signals (band 1 and band 19 frequencies).

Band 1 (2100MHz): Most cities
Band 19 (800MHz): Rural areas, mountains, lakes, islands, suburbs of Kyoto, Nara, Hokkaido (except Sapporo), and northern Okinawa

Your device must support Band 1 to ensure consistent signal coverage. Band 19 support is not required but can enhance connectivity in rural areas.

You can check the Compatibility page to see if your device is compatible or not with our monthly SIM card.

If your device is not listed or if you’re unsure about its supported bands, please contact us with the device name, model number, and the specific location where you plan to use the SIM card. We’ll review the compatibility and get back to you with more details.
