Troubleshooting
QR code won't scan or is rejected
What to do when the camera won't read the code or your phone says it's invalid.
The camera won't read the code
- Show the QR code on a different screen at full brightness, and avoid glare.
- Zoom the code so it fills most of the camera frame.
- Use manual entry instead; your SM-DP+ address and activation code are in your order email and account.
"This code is no longer valid" or "Unable to complete"
- Each eSIM QR code can usually be used only once. If the eSIM appears in your phone's SIM list, it's already installed; don't scan again.
- Make sure you're on stable Wi-Fi and try again in a few minutes.
- Check your phone is carrier-unlocked.
If the code still fails, contact support with your order number. Please don't delete any partially installed eSIM before we've checked it.
