Changing the Apple ID does not normally remove or deactivate an eSIM already installed on the same iPhone. Cellular profiles are managed separately from the account used for iCloud and App Store services.
If service stopped at the same time, check whether the phone was also erased, restored, transferred or had network settings changed. Those events are more relevant than the Apple ID sign-in itself.
Do not delete the eSIM to match the new account. Preserve the profile while identifying what else changed.
Quick answer: Confirm that the eSIM still appears and is enabled, select it for mobile data and test with Wi-Fi off. Then check plan validity, carrier settings, roaming and whether the iPhone was restored or replaced.
Check whether the profile remains installed
Open Settings > Mobile Service or Cellular and look for the travel line. If it is present, turn it on and select it for data.
Use the activation-status checks to separate profile presence from provider plan status.
Identify any simultaneous device change
- The iPhone was erased or restored.
- Data was moved to a new iPhone.
- Network settings were reset.
- The travel line was turned off.
- A different SIM became the mobile-data default.
If the eSIM was installed on another phone, review the device-transfer limitations before attempting the QR code again.
Restore the connection, not the Apple ID
- Select the travel eSIM for mobile data.
- Enable its required roaming setting.
- Disable automatic data switching.
- Toggle airplane mode once.
- Check for iOS and carrier-settings updates.
For manual NoveSIM APN entry use data.esim. If signal appears without data, follow the connection diagnostic.
If the profile has disappeared
Do not assume the original QR code is reusable. Contact NoveSIM support with the order reference, device model and explanation of any erase or transfer.
NoveSIM plans are data-only, and their validity is not paused by signing out of an Apple ID.

FAQ
Is an eSIM tied to my Apple ID?
An installed cellular profile is not normally controlled by changing the Apple ID used for iCloud or purchases.
Can signing out delete the eSIM?
Signing out alone should not normally delete it, but erasing or transferring the iPhone can change the device state.
Should I scan the QR code again?
Not if a profile is already present. If it disappeared, ask the provider whether reinstallation is permitted.
Does changing Apple ID pause validity?
No. Plan validity follows the provider’s conditions, not the Apple ID session.
Final Recommendation
Treat the Apple ID change as a timing clue, not the presumed technical cause.
Verify the installed line and any erase, transfer or settings change, then restore mobile configuration without deleting the profile.
