If you encounter the “There’s no longer valid code” error after activating your eSIM Korea via QR code or manual activation code on your iPhone, it may be due to a poor internet connection, an enabled VPN, or too many eSIMs installed on the device.

How to Fix

– Ensure your phone is connected to a stable Wi-Fi or cellular network before installing the eSIM Korea.
– A reliable internet connection is required for verification.
– Remove any unused eSIMs from your device.
– Proceed to activate the eSIM Korea.

2. Verify eSIM Korea Installation
– If the eSIM is already installed, this error may appear after scanning the QR code.
– Follow these steps to confirm:
1. Go to Settings > Cellular > Select the eSIM Korea plan.
2. Ensure Turn On This Line is enabled.
3. If the eSIM Korea appears and is enabled, it should connect automatically.
