If your eSIM QR code isn’t working, don’t panic. This is a common issue travelers encounter during installation.
Typical problems:
- QR code won’t scan
- Camera doesn’t recognize it
- Installation fails
- Invalid code message
Important:
In most cases, the QR code is fine — the issue is caused by setup conditions. Most users fix this in minutes.
Most common cause — camera can’t read code
Your phone may fail to scan if:
- Screen brightness is low
- QR is blurry
- Lighting is poor
- Screen glare exists
Fix:
- Increase brightness
- Clean camera lens
- Move to better lighting
- Hold phone steady
Second cause — QR already used
Many eSIM QR codes can only be scanned once.
If you see messages like:
- Code invalid
- Already used
- Activation failed
it may mean the code was already installed.
Fix:
Check if eSIM profile already exists:
- Settings → SIM Manager → eSIM profiles
Third cause — scanning from same device
You can’t scan a QR code displayed on the same phone.
Fix:
Open QR code on:
- Another phone
- Laptop
- Tablet
- Printed copy
Then scan.
Fourth cause — unstable internet connection
QR activation requires internet. If your connection is weak or unstable, installation may fail.
Fix:
Connect to:
- strong Wi-Fi
- stable mobile data
Then retry.
Fifth cause — unsupported device
Some phones don’t support eSIM QR installation.

If your device isn’t supported, scanning won’t work.
Sixth cause — camera permission disabled
If camera access is blocked, scanning fails.
Fix:
- Settings → Apps → Camera → Permissions → Allow
Seventh cause — manual install required
Some networks require manual activation instead of QR scanning. If scanning fails repeatedly, use manual setup.
