Update to iOS 17.4 or later and use the latest version of the KKday App to quickly install your eSIM, saving you the trouble of manual input and making internet access abroad easier. ⚠️ Android users whose phones support eSIM can contact customer service for a dedicated one-click installation link.
Integrating solutions from three major telecom operators—Docomo, KDDI, and SoftBank—and using local Japanese IP addresses and native lines, it offers a rare multi-carrier option, resulting in more stable connections and lower latency.
A QR code will be sent after order confirmation. No mailing or physical SIM card ejector tool is required. Buy anytime, go anytime.
eSIM coexists with your original physical SIM card, allowing you to retain your original number and receive important text messages and calls without changing your card.
Installing an eSIM requires a Wi-Fi or other network connection. The Docomo IIJ plan starts timing immediately after installation, so it is recommended to install it just before use; SoftBank and KDDI plans support pre-installation without affecting the validity period.
The QR code can only be scanned once and cannot be used repeatedly. Do not delete the eSIM after installation to avoid affecting subsequent use.
When installing by scanning the QR code, please print the voucher before departure, or prepare another device that can display the voucher.
To manually add an eSIM, please refer to the eSIM details in the "Pre-trip Reminder," copy and paste the <SM-DP_Address> and <Activation Code>. The <Confirmation Code> is not required.
This eSIM uses native network services from KDDI, Docomo, and SoftBank in Japan, and is not for international roaming. Data roaming does not need to be enabled during use.
