If an iPhone is not detecting an eSIM, first determine whether the plan is missing from Settings or present but unable to connect. A missing line and a line showing No Service are different problems.
The exact iPhone model, its sales region, carrier-lock status and supported iOS version all matter. Do not assume that every version of the same model has identical eSIM support.
NoveSIM travel eSIMs are data-only. Their line can appear without a telephone number, which does not mean the iPhone failed to detect the profile.
Quick answer: Open Settings > Mobile Service or Cellular and look for the travel line. If it is absent, confirm compatibility and installation status; if it is present, enable it, select it for Mobile Data and troubleshoot registration without deleting it.
Is the eSIM Missing or Simply Offline?
If the line appears in Cellular settings, the iPhone has detected the profile. Switch the line on, select it for Mobile Data and enable Data Roaming on that line. A line that is visible but has no signal needs network troubleshooting, not another QR scan.
If no travel line appears, check the NoveSIM compatible-device list and verify the precise model under Settings > General > About. Also check Carrier Lock; an unlocked iPhone should not show a SIM restriction.
Run the Safe iPhone Checks in Order
- Connect to dependable Wi-Fi and install the latest iOS version supported by the device.
- Turn Airplane Mode on, wait briefly and turn it off.
- Restart the iPhone.
- Open Settings > General > About and wait for any carrier-settings update prompt.
- Return to Cellular settings and check whether the line now appears.
Apple recommends these reversible checks before contacting the provider. Do not erase network settings or the eSIM as a first step.
If the Line Appears but Mobile Data Does Not Work
Make the travel line the selected Mobile Data line and turn off Allow Cellular Data Switching. Leave Network Selection on Automatic. If NoveSIM requires manual APN entry, use data.esim with blank username and password.
Use the dedicated guide when an eSIM is connected without internet. Do not test a data-only plan by placing an ordinary call.
When to Contact NoveSIM Support
Contact NoveSIM Support if installation failed, the phone reports that the code is invalid or already used, or the line remains absent after compatibility checks. Provide the order number, model, iOS version, EID and exact error message through the verified support channel.
Never publish the QR code or activation details. Do not delete the installed eSIM unless NoveSIM Support specifically tells you to do so.

FAQ
Why is my iPhone not detecting my eSIM?
The profile may not be installed, the exact model may not support eSIM, the phone may be locked, or installation may have failed. First check whether the line appears in Cellular settings.
Does an eSIM need to show a phone number on iPhone?
No. A data-only NoveSIM line may appear without a conventional phone number.
Should I scan the QR code again?
Not if the profile already appears or the code may have been consumed. Repeated scanning can fail; contact Support for the correct next step.
Should I delete an eSIM that says No Service?
No. Check the active line, roaming, network selection and APN first, and delete it only if NoveSIM Support instructs you to.
Final Recommendation
When an iPhone is not detecting an eSIM, identify whether the profile is absent or merely offline before attempting another installation.
Confirm the exact model and lock status, complete Apple’s reversible checks and use data.esim only if manual NoveSIM APN entry is required.
Preserve the profile and activation credentials, then contact NoveSIM Support with the exact error if the line remains missing.
