How can I fix the "This code is no longer valid" error when adding my Qoolline eSIM?

If you’re adding a Qoolline eSIM to your device and see a “This code is no longer valid” message, don’t worry—this usually has a straightforward explanation. This error commonly means that either the eSIM has already been activated on a device, or there was a problem scanning the QR code, often due to a weak internet connection. Knowing the possible causes can help you resolve the issue quickly and get your Qoolline eSIM working without hassle.

Why This Error Happens:

1. Previously Used eSIM: If the eSIM has been added to a device before, it cannot be used again, similar to a one-time-use code.
2. QR Code Scanning Issue: A poor internet connection can sometimes cause the QR code to scan improperly, resulting in the “code no longer valid” error.

Checking for eSIM Installation
Before troubleshooting, it’s helpful to confirm if the eSIM is already installed:

• Open Settings: Go to your device’s Settings app.
• Tap General > About: In the "About" section, look for “ICCID” to check if your eSIM is active.
• Verify Cellular Plans: Return to Settings, tap “Cellular” or “Mobile Data,” and ensure your eSIM is listed here. If so, it’s already set up.

Common Causes of the Error:

1. Previously Added and Removed eSIM: Qoolline eSIMs are typically one-time use, so re-adding a removed eSIM won’t work.
2. Weak Internet Connection: A stable connection is essential for successful installation.
3. VPN Interference: An active VPN can sometimes disrupt eSIM setup, so turning it off during installation is recommended.
4. eSIM Limit on Device: Devices have a limit on the number of eSIMs they can handle, so make sure you haven’t reached this capacity.

Steps to Resolve the Error and Install Qoolline eSIM Successfully:

1. Disable VPN: If you’re using a VPN, turn it off before attempting installation.
2. Ensure a Strong Connection: Use a stable internet connection to prevent interruptions during setup.
3. Remove Unused eSIMs: Free up space by deleting any eSIMs you no longer use.
4. Update Device Software: Ensure your device’s software is up-to-date, as updates can resolve potential installation issues.
5. Try Manual Entry: If scanning the QR code doesn’t work, consider entering the details manually.

Conclusion:
If you continue to see the “This code is no longer valid” message, double-check that the eSIM hasn’t been previously activated and that you’re following the recommended steps for a stable installation. If issues persist, our customer support team is here to assist you.
