If your eSIM QR code is not scanning, the most common reasons are low screen brightness, blurry display, camera focus issues, damaged image quality, expired or already used QR code, unsupported device settings, or trying to scan from the same phone screen.
This is one of the most common eSIM installation problems. You are ready to activate your plan, but the phone camera refuses to recognize the QR code.
The good news: in most cases, the QR code is fine and the issue is easy to fix in a few minutes.
You may notice:
- camera sees QR but does nothing
- cannot focus on code
- invalid code message
- scan failed repeatedly
- same phone cannot scan its own screen
This guide explains exactly why your eSIM QR code is not scanning, how to fix it quickly, and how to install your eSIM successfully.
Quick answer: Use a second screen, increase brightness, clean the camera lens, enlarge the QR code, keep steady focus, and manually enter activation details if supported.
1. You Are Trying to Scan the QR Code From the Same Phone
This is the #1 reason.
If the QR code is displayed on the same device where you want to install the eSIM, the camera cannot scan its own screen.
Fix:
- Open the QR code on another phone
- Use a tablet, laptop, or printed copy

Phones need proper focus distance.
Fix:
- Move slowly closer and farther
- Hold the phone steady
6. QR Code Was Already Used

Fix:
- Check your NoveSIM account
- Request reissue if available
