This error message appears when you're trying to add an eSIM that has already been added or if the QR code was only partially scanned due to a poor connection.
To confirm whether the eSIM has been installed, please follow these steps:
Go to Settings.
Select General.
Tap About and scroll down.
If the eSIM is installed and active, you should see the ICCID [NUMBER] along with an extra digit, indicating that the eSIM line is enabled under your Cellular Plans.
Please be aware that if the eSIM has been removed and you try to reinstall it, this will not be possible.
However, if you are installing the eSIM for the first time, the error message could be due to a poor connection, an active VPN, or having too many eSIMs installed on your device.
To successfully install your eSIM, please follow these steps:
Disable any VPN.
Make sure you have a strong and stable internet connection.
Remove any eSIMs you no longer use.
Ensure your software is updated to the latest version.
Try installing the eSIM using a different installation method than before
