A Mexico eSIM can show signal while mobile data still fails because the wrong line is selected, roaming is off, the package is inactive or the APN is missing.
Quick answer: Keep the profile installed. Select it for mobile data, enable data roaming, disable data switching and test with Wi-Fi off. Then check plan status before changing the network or APN.

Make sure the Mexico eSIM is switched on and assigned to mobile data. Disable the home line temporarily if the phone’s display is ambiguous.
Check package status and APN
Confirm that validity has started and data remains. For NoveSIM, enter data.esim only when the APN must be added manually.
Refresh without deleting
Toggle airplane mode for 30 seconds, restart once and leave network selection on Automatic initially. Use the broader Mexico troubleshooting guide if data still fails.
FAQ
Why is there signal but no internet?
Network registration can succeed even when data settings or package status are wrong.
Should roaming be on?
Yes for many travel eSIMs.
Should I delete the eSIM?
No; preserve it for diagnosis because the QR code may be single-use.
What APN does NoveSIM use?
Use data.esim when manual APN entry is required.
Final Recommendation
Check line selection, roaming and package status in that order. Preserve the eSIM and contact support with screenshots if the connection still fails.
