There are several reasons you might be unable to scan your eSIM QR code. Here are a few things you can try.
Check if your phone is compatible with eSIM - Confirm that your phone supports eSIM technology. Not all phones are eSIM compatible, so it is important to check this first.
Check the QR code - Make sure the QR code you are trying to scan is not damaged or distorted. If the code is not clear or legible, try scanning it again or request a new code.
Adjust the lighting - Poor lighting can affect the QR code scanner's ability to read the code. Try adjusting the lighting in your room so the QR code is well lit.
Move closer to the QR code - If you are too far away, the scanner may not be able to read the code. Move closer and try again.
Restart your phone - If none of the above steps work, restart your phone and try scanning the QR code again. This can often resolve software issues.
