When setting up an eSIM, there may be times when you have trouble scanning the QR code.
"Cannot scan the QR code" "The camera does not respond when pointed at it" "An error message is displayed" and so on, there are multiple possible causes.
In this article, we will clearly introduce the main reasons why the eSIM QR code cannot be scanned, along with the troubleshooting methods you should check in order.
Checklist to Confirm First
| Check Item | Check |
|---|---|
| Connected to Wi-Fi | □ |
| QR code is clearly displayed | □ |
| There is sufficient brightness | □ |
| The camera lens is not dirty | □ |
| Scanning from the eSIM setup screen | □ |
| The device is eSIM compatible | □ |
By confirming these items first, you may be able to resolve many issues.
The QR Code is Blurry
If the QR code is too small or the image quality is low, it may not be scanned correctly.
- Zoom in on the screen
- Use a high-quality PDF
- Check if the screenshot is not blurry
The Camera Cannot Recognize the QR Code
If the distance between the smartphone and the QR code is too close or too far, scanning may fail. Point the camera at the appropriate distance and wait a few seconds for it to focus.
Confirm if Scanning from the Setup Screen
The eSIM needs to be scanned from the smartphone's "Add eSIM" screen, not from a regular camera app. The operation method may vary by model, so please check the setup guide as well.
If It Still Cannot Be Scanned
- Restart the device
- Update the OS to the latest version
- Display the QR code on a different screen or device
- Check if a manual input code is provided
- Contact the eSIM service support
If the QR code cannot be scanned after multiple attempts, follow the instructions from the provider.
Frequently Asked Questions
What are the reasons why the eSIM QR code cannot be scanned?
The main reasons include low image quality of the QR code, a dark screen, the camera not being in focus, trying to scan from a screen other than the eSIM setup screen, and the device not being eSIM compatible. Start by checking the basic items.
Is it okay to scan the QR code with a regular camera app?
On many smartphones, the QR code is scanned from features like "Add eSIM" in the eSIM setup screen. It may not be possible to set it up using a regular camera app, so please follow the instructions for your device.
The QR code is blurry and cannot be scanned.
Display the QR code in high quality, or use a PDF version if available. Enlarging a screenshot too much can also reduce image quality.

Generally, there is no problem with just scanning, but the usage conditions may vary by eSIM service. Some eSIMs may have limits on the number of uses or installations, so please check the instructions for the service you purchased.
What should I do if I lost the QR code?
Check the email received at the time of purchase or your account page. The possibility of reissuing may vary by service, so if you cannot find it, please contact the eSIM provider.
Can I set it up manually if I cannot scan the QR code?
Some eSIMs support manual setup using the SM-DP+ address or activation code. Please check the provider's setup guide to see if this is available.
What should I do if it still cannot be scanned?
Restart your smartphone and try again after updating the OS to the latest version. If it does not improve, please contact the support for the eSIM service you are using.
