Trouble Shooting

Activation (start of usage period) is completed when the installed eSIM is connected to a supported network in the cuntry of use. The above activation error may appear if installation is performed outside the country of use. Please verify if the installation process has been completed successfully.

Installation can only be performed once per eSIM. If the installation has already been completed or if you attempt to install multiple times, you will receive an error message similar to the one displayed above.

If the installation is unsuccessful, please restart your device (power from OFF to ON), and attempt the installation by scaning a QR code or enter the QR code manually.

※The same display may also appear if the SIM lock has not been removed.
