If an eSIM is not working in Spain, identify the exact symptom before changing settings. A missing profile, No Service, signal without data and one failing app require different fixes.
Most travel-data failures can be diagnosed through plan status, SIM selection, roaming, network registration and APN checks.
NoveSIM plans are data-only, so use a website or map as the test rather than an ordinary call or SMS.
Quick answer: Confirm the plan includes Spain and remains active, select NoveSIM for Mobile Data, enable Data Roaming on that line and leave Network Selection on Automatic. Use data.esim only when manual APN entry is required. Do not delete the profile.

| Symptom | First check |
|---|---|
| Profile is missing | Confirm installation was completed on the same phone |
| No Service | Line enabled, plan active and automatic network selection |
| Bars but no internet | Mobile Data line, roaming and APN |
| Only one app fails | App permissions, VPN and service status |
Check Plan Coverage and Validity
Open the order information and confirm Spain is included, activation conditions have been met, validity has not expired and data remains. For a Canary Islands itinerary, verify the exact product rather than assuming coverage from the name alone. Current options are on the Spain eSIM page.
Correct the Dual-SIM Settings
- Switch on the NoveSIM profile.
- Select it as the Mobile Data line.
- Enable Data Roaming on NoveSIM.
- Disable automatic data switching.
- Keep Data Roaming off on the primary SIM.
- Turn off Wi-Fi and test a normal website.

Refresh Network Registration
Leave Network Selection on Automatic, use Airplane Mode for about 30 seconds and allow several minutes after reconnecting. Move near a window or outdoors if the phone is inside an airport, underground station or thick-walled building.
A visible network is not necessarily authorised for the plan. Avoid repeatedly forcing carriers unless NoveSIM Support names an alternative.
Check the NoveSIM APN
If manual entry is required, set APN to data.esim and leave username and password blank. Save and select the APN. Do not copy settings from a Spanish operator or another provider. The Spain APN guide provides further context.
When to Contact Support
Do not delete the installed eSIM or reset the phone. Contact NoveSIM Support with the order number, exact model, Spanish city, displayed network and safe screenshots of line selection, roaming and APN. Hide the QR code and activation details.

FAQ
Why is my eSIM not working in Spain?
The plan may be inactive, the wrong SIM may handle data, roaming may be off, registration may have failed or the APN may be missing.
Should Data Roaming be on?
Usually yes for a travel eSIM. Enable it on NoveSIM and keep it off on the primary line.
What APN does NoveSIM use?
When manual entry is required, use data.esim with blank username and password.
Should I reinstall the eSIM?
No. Preserve the installed profile and delete it only if NoveSIM Support explicitly instructs you.
Final Recommendation
When an eSIM is not working in Spain, check plan status and the selected data line before changing advanced settings.
Enable roaming on the travel profile, refresh automatic registration and verify data.esim only if an APN is required.
Keep the profile installed and send precise diagnostics to Support if service does not return.
