eSIM activation failure is typically caused by network settings, system version, QR code, or device compatibility issues. Follow these steps to troubleshoot — most problems can be resolved within 5 minutes.
If all the above steps fail, the eSIM configuration itself may have an issue. Please contact customer service immediately — we will resend the eSIM configuration for free.
Step 4: Reinstall eSIM
If auto-connect fails, you can manually select a carrier.
Step 6: Manually select carrier
Step 5: Disable VPN and proxy
If the above steps do not work, try deleting the old profile and reinstalling.
Step 3: Check system updates
After arriving at the destination, eSIM requires data roaming to be enabled to connect to local networks. This is the most common cause of activation failure.
Step 2: Enable data roaming
Step 1: Confirm phone supports eSIM
The most common eSIM activation failure causes include: data roaming not enabled, outdated phone system, QR code scan failure, device not supporting eSIM, and conflicts from duplicate installations. Here is a step-by-step troubleshooting guide.
From checking phone compatibility to completing installation — just 3 minutes. Follow the tutorial step by step and set up your eSIM with ease.
View Installation TutorialeSIM installation typically takes only 3-5 minutes. After scanning the QR code, your phone automatically downloads the configuration file, and you can use it once complete. The entire process is very simple with no physical operations required.
We recommend connecting to WiFi during installation, as downloading the configuration file requires a network connection. The file is very small (typically a few KB), so downloading is very fast. After installation, the eSIM is in a pending activation state — enable roaming upon arrival for auto-connection.
Yes, and we recommend installing in advance. The eSIM won't activate immediately after installation — it needs to connect to the local network at the destination before billing starts. We recommend installing before departure and enabling roaming upon arrival.
Common causes include: system version too old, unstable network, unclear QR code. We recommend updating your system to the latest version, ensuring stable WiFi, and scanning in good lighting. If it still fails, contact customer service for a free eSIM re-issue.
iPhone: Settings > Cellular > Select the eSIM > Delete eSIM. Android: Settings > Network & Internet > Mobile Network > Select the eSIM > Remove. After deletion, you'll need a new QR code to reinstall.
Ensure the QR code image is clear and complete, with no obstructions or reflections. Try zooming in on the QR code image and scanning in a well-lit environment. If received via email, save the QR code to your photo album and scan from there. If scanning still fails, contact customer service for a manual activation code.
