Most Belgium eSIMs configure their APN automatically. Manual APN entry is a targeted troubleshooting step, not the first change to make when data does not start.
Before editing anything, confirm that the eSIM is enabled, selected for mobile data and allowed to use Data Roaming. A correct APN cannot help if the phone is sending data through the wrong line.
For NoveSIM travel eSIMs, the manual APN is data.esim when manual entry is required. The plans are data-only and do not provide a Belgian number, ordinary calls or carrier SMS.
Quick answer: Leave the APN automatic first. If the Belgium eSIM still has no data after the active-line and roaming checks, enter data.esim in the APN field, leave username and password empty, save the setting and test again.

- Open the phone’s SIM or Mobile Network settings.
- Confirm the Belgium eSIM is switched on.
- Select it as the mobile-data line.
- Turn Data Roaming on for the Belgium eSIM.
- Turn roaming off for the home SIM.
- Disable automatic mobile-data switching.
- Leave Network Selection on Automatic.
Wait briefly for network registration, switch aeroplane mode on and off once, then test an ordinary webpage. If data works, do not edit the APN.
Enter data.esim only when required
If manual configuration is necessary, create or edit the APN for the travel eSIM and enter data.esim exactly. Leave username and password blank unless NoveSIM support provides different plan-specific instructions.
Save and select the new APN where the phone requires this. Return to the data settings and test with Wi-Fi off. Avoid changing proxy, port, authentication type or other fields without instructions.
APN steps on iPhone
Apple menu names vary by iOS version and operator profile. Open Settings, choose Mobile Service or Cellular, select the Belgium eSIM and look for Mobile Data Network if that menu is available.
Enter data.esim in the Mobile Data APN field only when required. Some carrier configurations hide the APN menu; that does not automatically indicate a fault. The Belgium eSIM iPhone guide covers the wider dual-SIM setup.
APN steps on Android
Android wording differs by manufacturer. Open Settings, then Network and Internet, Connections or SIM Manager. Choose the Belgium eSIM and open Access Point Names.
Add an APN named clearly for the travel line, enter data.esim, save it and select it. Restart mobile data rather than deleting the eSIM. See the Belgium eSIM Android guide for device-menu context.
If data still does not work
Return network selection to Automatic, restart the phone once and test in an open area. Confirm the plan is active and has remaining data. If signal is present but speeds are poor, use the slow Belgium data guide.
Do not delete the installed eSIM. Contact support with the phone model, location, selected network and screenshots of the relevant settings. The full Belgium eSIM troubleshooting guide provides the ordered sequence.

FAQ
What is the NoveSIM APN for Belgium?
The manual APN is data.esim when manual entry is required.
Should username and password be filled in?
Leave them blank unless NoveSIM support gives different instructions for the specific plan.
Why can I not see the APN menu?
Some device or carrier profiles hide manual APN controls. Check the active line and roaming first, then contact support rather than deleting the eSIM.
Should I delete and reinstall the eSIM?
No. Do not delete the installed profile unless NoveSIM support specifically instructs you.
Final Recommendation
Treat APN entry as a precise fallback. First select the Belgium eSIM for data, enable its roaming and allow automatic network registration. If manual entry is still needed, use data.esim exactly, leave unrelated fields unchanged and keep the installed eSIM in place while troubleshooting.
