No technology is perfect. While using your phone, you may discover that your eSIM is not responding and you do not have a network. This can be frustrating, especially if you’ve just landed at your destination.

Don’t let this ruin your good mood. This guide will help you troubleshoot your eSIM if ever it has issues.

Issue 1: eSIM Activation Delays

Some eSIM users experience delays activating their eSIMs after scanning the eSIM QR code.

Solution:

  • Check carrier compatibility: Make sure that your carrier of choice supports eSIM and has activated the service on your account.
  • Reboot your device: If you restart your gadget, your network connection will refresh.
  • Verify QR code: Confirm you scanned the correct QR code provided by your carrier.
    If activation still stalls, opt for manual activation. Contact your carrier's customer service for the next steps.

Issue 2: Device Not Compatible with eSIM

If your device does not support eSIM technology, you will encounter problems installing it. For example, if you own an Apple device, know that iPhone models XS to the latest versions are compatible with eSIM technology. Older iPhones are not compatible with it.

Solution:

  • Check device compatibility: Visit your manufacturer’s website or carrier’s eSIM compatibility list.
  • Update software: Some device models add eSIM support via updates. Make sure that your device runs the latest operating system.
    If your device isn’t eSIM-compatible, consider upgrading or sticking with a physical SIM.

Issue 3: QR Code Not Scanning

The QR code for eSIM installation won’t scan or is invalid.

Solution:

  • Clean your camera lens: A smudge or dirt could affect the scan.
  • Improve lighting: Ensure the QR code is well-lit and free of glare.
  • Use manual entry: Most devices allow you to enter the eSIM details manually. Look for the activation code or URL in the instructions provided by your carrier.
    If the QR code is still invalid, request a new one from your carrier.

Issue 4: eSIM Not Detected by Device

After installation, the eSIM is not recognized.

Solution:

  • Check settings: Go to your device’s network or cellular settings to ensure the eSIM is installed and active.
  • Prioritize eSIM: If you're using dual SIMs, set the eSIM as the primary line under the settings.
  • Reset network settings: This clears potential software glitches (note: this will erase saved Wi-Fi networks).
    Reinstall the eSIM profile or contact the carrier for further troubleshooting if the issue persists.

Issue 5: Poor Signal or No Service

After activating the eSIM, you experience poor signal strength or no service.

Solution:

  • Verify carrier coverage: Confirm if the carrier has coverage in your area.
  • Enable roaming (if applicable): If you are using an eSIM for international use, know that some eSIM plans require roaming to be activated.
  • Switch network settings: Manually toggle between 4G/5G to see which works best.
    If the problem continues, reach out to your carrier for signal-related issues.

Issue 6: eSIM Conflicts with Physical SIM

Using both an eSIM and a physical SIM causes issues, such as dropped calls or conflicting data plans.

Solution:

  • Assign SIMs to specific functions: For example, use one SIM for calls and texts and the other for data. Adjust these in your device settings.
  • Disable the unused SIM: Temporarily turn off the physical SIM if you face connectivity issues with the eSIM.

Issue 7: eSIM Profile Removal by Mistake

You accidentally deleted the eSIM profile.

Solution:

  • Reinstall the eSIM: Use the original QR code or activation code to reinstall.
  • Contact your carrier for a replacement if you’ve lost the activation details.

Issue 8: No Internet After eSIM Activation

Cellular data doesn’t work after enabling the eSIM.

Solution:

  • Check data settings: Ensure the eSIM is the default data line.
  • Enter APN settings manually: Some carriers require you to manually enter Access Point Names (APNs) for internet access.
    If the issue persists, try toggling airplane mode on/off or restarting your device.

Conclusion

While eSIM technology offers incredible convenience and flexibility, its installation process can sometimes present challenges.
