“This code is no longer valid” error

This error usually means the QR code wasn't scanned correctly, or the eSIM is already installed.

Try this:

• Ensure a strong connection and rescan the QR code.
• On iPhone: Settings > General > About → check ICCID; if the eSIM is active under Cellular Plans, ICCID will appear.
• Note: most eSIMs install only once; removed eSIMs often cannot be reinstalled. If issues continue, contact your carrier.
