This error means the QR code (eSIM profile) has already been used once. Each eSIM QR code can only be installed one time.
Please check:
- Is the eSIM already installed? Look in Settings → Cellular (SIMs) — if it's already listed, there's no need to scan again
- Was this eSIM installed and then deleted before? A deleted eSIM cannot be reinstalled with the same QR code
If you never installed it, or deleted it by mistake, contact our support team — we'll check the status and help you out.
