The correct APN for a NoveSIM Sri Lanka travel eSIM is data.esim. Enter it only for the travel eSIM and only when the APN is missing or mobile data does not start. Do not copy a domestic operator’s APN or another provider’s settings.
An APN controls how the phone routes mobile data after network registration. It does not make an incompatible phone support eSIM, repair an expired plan or create coverage where there is no signal.
NoveSIM travel eSIMs are data-only. We do not provide conventional calls, SMS or a local number.
Quick answer: Select the Sri Lanka eSIM, enter data.esim in the APN field, leave username and password empty unless instructed otherwise, save the entry and test with Wi-Fi off. Keep the eSIM installed.

|---|---|
| APN | data.esim |
| Username | Leave empty |
| Password | Leave empty |
When Should You Change the APN?
Check the APN when the eSIM is enabled and shows network signal but pages do not load. First confirm that the travel eSIM is selected for mobile data and that data roaming is on for that line.
For the full symptom sequence, use the Sri Lanka signal-without-data guide.
Enter the APN on iPhone
- Open Settings > Cellular or Mobile Service.
- Select the Sri Lanka eSIM.
- Open Cellular Data Network when available.
- Enter data.esim in the APN field.
- Return to the previous screen and test mobile data.
If the APN menu is not available, the profile may manage it automatically. Do not delete the profile to reveal the menu.
Enter the APN on Android
- Open Mobile Network or Connections settings.
- Select the Sri Lanka eSIM.
- Open Access Point Names.
- Add a new APN with data.esim.
- Save and select the new entry.
- Test with Wi-Fi off.
What Not to Change
Do not invent MCC, MNC, proxy, port or authentication values. Leave them automatic or blank unless the plan instructions explicitly provide them. An incorrect value can prevent data from routing.
After Saving the APN
- Confirm the eSIM remains selected for mobile data.
- Enable data roaming on that line.
- Use Airplane Mode for about 30 seconds.
- Turn Wi-Fi off.
- Open a simple website.
If data.esim Does Not Fix the Connection
Check plan validity, remaining allowance, location and network registration through the Sri Lanka eSIM diagnostic guide. Do not repeatedly create APN entries or delete the eSIM.

FAQ
What is the NoveSIM APN in Sri Lanka?
The APN is data.esim.
Should username and password be filled?
Leave them empty unless your specific plan instructions state otherwise.
Why is the APN menu missing?
The profile or device may manage it automatically. Contact support rather than deleting the eSIM.
Will an APN fix no signal?
No. APN settings route data after registration; no service is a different problem.
Final Recommendation
Use data.esim as the Sri Lanka eSIM APN for NoveSIM and avoid unrelated domestic settings.
Change the APN only after confirming the correct data line and roaming.
If mobile data still fails, keep the eSIM installed and continue with plan, network and coverage diagnostics.
