An eSIM can show signal and a network name while individual apps still fail to load.
The cause may be a depleted package, incorrect data routing, VPN or DNS filtering, app permissions or a captive Wi-Fi session.
Keep the installed eSIM in place; deleting it can make diagnosis harder and the QR code may be single-use.
Quick answer: Turn Wi-Fi off and test a normal webpage. Confirm the eSIM is selected for mobile data, roaming is enabled when required and the plan has remaining data. Then pause VPN or private DNS and test one affected app again.
Separate an app problem from a data problem
If no webpage loads, follow the signal-without-data guide. If browsers work, check whether only one app is affected.
Check permissions and filtering
Allow cellular data for the affected app. Temporarily pause VPN, ad blocking or private DNS, then restore each service individually after testing.
Verify APN and data routing
Disable mobile-data switching and use APN guidance. For NoveSIM, the manual APN is data.esim. Contact NoveSIM Support with screenshots if needed.

FAQ
Why does the browser work but an app does not?
The app may lack cellular permission or be blocked by VPN, DNS or its own service status.
Should I reset all network settings?
Not first; use the targeted checks before a broad reset.
What APN does NoveSIM use?
Use data.esim when manual APN entry is required.
Should I delete the profile?
No, keep it installed unless support instructs otherwise.
Final Recommendation
First identify whether all data or only one app is failing.
Correct permissions, filtering and data-line settings one at a time.
Preserve the eSIM and provide support with precise test results.
