Reminders
The departure date selected at the time of booking is for reference only; you do not need to activate it on that day. The eSIM can be installed in advance and must be activated by connecting to the network at the destination within the validity period.
A network connection is required during installation. If an error occurs while scanning the QR code, please check if the eSIM has already been successfully installed. If it has, there is no need to scan it again.
To add an eSIM manually, please go to 'Pre-departure Reminder' to copy the SM-DP+ Address and Activation Code. No confirmation code is required.
If it shows 'Activating' or 'Activation Unsuccessful' during pre-installation, do not delete the eSIM. Re-enable it upon arrival.
VPN may affect connection stability. If you experience issues, it is recommended to disable the VPN first.
Network quality may vary depending on location, signal coverage, and the number of users. If you experience connection issues, please contact our 24-hour online customer support for assistance.
