If your Sri Lanka eSIM is not working, identify the symptom before changing settings. An installation failure, missing profile, no-service problem, signal-without-data problem and slow connection require different checks.
Start with the least destructive actions: confirm the plan, line and settings, then refresh the connection. Do not delete the eSIM unless support specifically instructs you to do so.
NoveSIM travel eSIMs are data-only. We do not provide conventional calls, SMS or a Sri Lankan number, so inability to place a normal call is not evidence that mobile data has failed.
Quick answer: Confirm that the profile is installed, enable the line, select it for mobile data, turn on data roaming and keep network selection automatic. If signal appears without internet, check the data.esim APN.

First Identify the Symptom
| Symptom | Start here |
|---|---|
| QR code will not install | Compatibility, carrier lock and installation method |
| Profile installed but no service | Location, line status and network registration |
| Signal but no internet | Data line, roaming and APN |
| Internet works but is slow | Coverage, congestion and network mode |
| Worked, then stopped | Plan validity, allowance and local coverage |
If the eSIM Will Not Install
Confirm that the exact phone supports eSIM and is unlocked. Use stable Wi-Fi, display the full QR code and check whether the profile has already appeared in the SIM settings. Follow the Sri Lanka installation guide before attempting another method.
If the Phone Shows No Service
- Confirm that you are in Sri Lanka and the plan includes the country.
- Switch on the travel eSIM.
- Use Airplane Mode for about 30 seconds.
- Restart the phone once.
- Keep network selection automatic.
- Check plan validity and supported networks.
If There Is Signal but No Internet
Select the eSIM for mobile data, enable data roaming on that line and disable automatic data switching. Confirm that the NoveSIM APN is data.esim. Use the focused signal-without-data guide for the full sequence.
If the Connection Is Slow
Test outdoors or away from thick walls, pause background downloads and try LTE or 4G if an unstable 5G connection is selected. Speed depends on coverage, congestion, device and plan conditions. See Sri Lanka slow-eSIM troubleshooting.
If the eSIM Worked and Then Stopped
Check the plan’s validity and remaining allowance before changing network settings. Consider whether you moved to a train, mountain route or remote area where reception is weaker.
When to Contact Support
Send the order reference, phone model, current location, displayed network name and screenshots of the data-line, roaming and APN settings. Do not post the complete QR code publicly.

FAQ
Why is my Sri Lanka eSIM not working?
The cause may be installation, activation, network registration, data-line selection, roaming, APN, plan validity or local coverage. Identify the symptom first.
What is the NoveSIM APN?
The APN is data.esim. Do not substitute another provider’s or domestic operator’s APN.
Should I select a network manually?
Keep automatic selection as the default. Test a supported partner manually only when necessary, then return to automatic selection.
Should I reinstall the eSIM?
Do not delete it. Contact support first because many QR codes are intended for one installation.
Final Recommendation
When a Sri Lanka eSIM is not working, diagnose the visible symptom before changing several settings at once.
Check the installed line, data selection, roaming, automatic network choice and data.esim APN in a controlled sequence.
Keep the profile installed and provide support with precise device, location and settings information if the issue remains.
