About the 5G Travel SIM card, due to the SIM card's specifications, it is likely not compatible with most pocket Wi-Fi devices. It may work depending on the device, but we cannot guarantee anything. Please note that if it is inserted or installed into a pocket Wi-Fi device, it will not be covered by the SIM compatibility insurance and we will not be able to provide any refund.

On the other hand, our 4G Travel SIM cards are compatible with pocket Wi-Fi devices. We recommend the 4G Travel SIM cards if you want to use it in your pocket Wi-Fi device.
However, as a general rule, configuring the APN setting on your device is required. APN setup procedures differ from device to device.

Please refer to your device’s manual or contact the manufacturer for complete instructions, and ensure that your device is capable of adjusting the APN settings.

You can find the instructions for configuring APN settings at this link: https://www.sakuramobile.jp/apn-settings_travelsim/.

Also, please make sure that your device supports the conditions below:
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 are used.
Band 1 (2100MHz)： Most cities
Band 19 (800MHz)： Rural areas, mountains, lakes, islands, and suburbs of Kyoto, Nara, and Hokkaido except for Sapporo, North of Okinawa, and Takayama

If you don't know how to do the APN settings on your pocket wifi and don't have the complete instructions, then we suggest you rent our Pocket WiFi instead.
