A Spain eSIM can show signal while mobile data remains unavailable because the wrong line is selected, roaming is off, the network registration is incomplete or the APN is missing.
Work through the settings in order and test a simple webpage after each change. Do not delete the eSIM, because reinstalling may not be possible with the same activation details.
NoveSIM plans are data-only. Calls and SMS are not a connection test; use a webpage or messaging app after confirming the data settings.
Quick answer: Select the Spain eSIM for mobile data, enable data roaming on that line, toggle airplane mode, return network selection to automatic and set APN to data.esim if required. Keep the profile installed.

Refresh network registration
Enable data roaming on the travel line when the plan requires it, toggle airplane mode for several seconds and restart the phone once. Keep network selection automatic unless support asks for a manual test.
Check APN and allowance
If an APN is required, enter data.esim exactly and leave unnecessary fields blank. Confirm that the plan has started, Spain is included and data remains. Use the broader connected-without-data guide for additional checks.
When to contact support
Record the device model, location, displayed network and completed steps. Contact support before deleting or resetting the eSIM. Review Spain eSIM troubleshooting for destination-specific follow-up.
