Common Activation Error Causes

QR Code Already Used
Each eBanano QR code is single-use and tied to one device. If the code has been scanned before — even unsuccessfully on another phone — it may be marked as used and will need to be replaced by our support team. See the fix below for what to do next.
Poor Wi-Fi During Installation
Poor Wi-Fi During Installation
Downloading an eSIM profile requires a stable internet connection. A dropped or slow Wi-Fi signal mid-installation can interrupt the process and leave the activation in a broken state. See the fix below for how to retry successfully.
Device Carrier Lock
Device Carrier Lock
If your phone is locked to your home carrier, it may refuse to install an eSIM profile from a different network. This is one of the most common activation blockers for travelers. See the fix below, or visit the Device Compatibility guide for full details.
Incorrect Date / Time Settings
Incorrect Date / Time Settings
eSIM profiles use time-sensitive security certificates. If your phone’s date or time is significantly off, the certificate check will fail and activation will be rejected. The General Recovery Steps section below explains how to fix this quickly.
Fixing Each Issue
QR code already used error
QR code already used error
Each QR code can only be scanned once, on one device. If you see an “already used” or “activation code already redeemed” error, the code is no longer valid for fresh installation.What to do:
- Do not scan the code again — it won’t help.
- Contact eBanano Support with your order number and explain that your QR code has been flagged as used.
- Our team will verify your order and issue a replacement activation code promptly.
Installation failed / couldn't download profile
Installation failed / couldn't download profile
This usually happens when your Wi-Fi drops or slows down mid-download, or when a VPN interferes with the secure connection to the eSIM server.What to do:
- Disconnect from any VPN you have running.
- Move closer to your Wi-Fi router or switch to a more reliable network.
- Restart your phone.
- Try the installation again from Settings → Cellular / Mobile Data → Add eSIM / Add Data Plan.
- If the same QR code fails repeatedly, contact support — it may need to be reissued.
Not supported by carrier or Profile installation failed
Not supported by carrier or Profile installation failed
This error almost always means your phone is carrier-locked — it’s been restricted by your home carrier to only work with their own SIM or eSIM profiles.What to do:
- Contact your current carrier (the one your phone’s main SIM belongs to) and ask them to unlock your device.
- Most carriers will unlock a phone that has completed its contract or is fully paid off — sometimes just by asking.
- Once unlocked, try the eBanano installation again.
- See the Device Compatibility guide for more detail on carrier locks.
The activation code is invalid error
The activation code is invalid error
This can happen if the QR code was scanned at an angle or in poor lighting, resulting in a misread. It can also happen if you’re trying to use a QR code meant for a different device type.What to do:
- Try scanning again in good lighting, holding the camera steady and centred on the QR code.
- Alternatively, use manual entry: most phones offer an “Enter details manually” option during eSIM setup. Your eBanano confirmation email includes the activation code as a text string — enter it exactly as shown.
- Double-check you’re using the QR code from your most recent eBanano order confirmation email.
- If the code still fails, contact eBanano Support for a fresh one.
General Recovery Steps
If you’re not sure which error applies to you, or you want to start fresh, follow these steps in order:1
Check your Wi-Fi connection
Make sure you’re on a stable, fast Wi-Fi network. Disconnect from any VPN. Avoid public hotspots if possible — home or hotel Wi-Fi works best.
2
Verify your phone's date and time
Go to Settings → General → Date & Time (iPhone) or Settings → General Management → Date and Time (Android) and enable Set Automatically. This ensures your device clock is accurate and won’t fail certificate checks.
3
Restart your phone
A full restart clears any cached errors from a previous failed attempt. Shut down completely, wait 15 seconds, then power back on.
4
Try the activation again
Return to Settings → Cellular / Mobile Data → Add eSIM and scan your QR code (or enter the code manually). Take your time — make sure the camera reads the code cleanly.
5
Contact support if still failing
If you’ve made it through all four steps and activation still fails, don’t keep trying solo. Reach out to eBanano Support with your order number and describe the exact error message you’re seeing. We’ll take it from there.
