If your Sri Lanka eSIM shows signal bars or a network name but websites do not load, the phone is usually registered on a network but is not routing mobile data through the correct line. The most common causes are the wrong data SIM, disabled data roaming or a missing APN.
This page is specifically for a signal-without-data problem. If the eSIM is missing, will not install or shows no service, use the broader Sri Lanka eSIM troubleshooting guide.
NoveSIM travel eSIMs are data-only. We do not provide a Sri Lankan number or conventional calls and SMS, so test the connection with a website rather than by attempting a normal phone call.
Quick answer: Turn off Wi-Fi, select the Sri Lanka eSIM for mobile data, enable data roaming on that eSIM and confirm that its APN is data.esim. Then use Airplane Mode briefly and test a simple website. Do not delete the installed eSIM.

Confirm That the Problem Is Mobile Data
Wi-Fi can hide a mobile-data failure. Turn Wi-Fi off and check whether the status bar still shows a mobile network. Then open a simple web page. If the phone shows signal but the page does not load, continue with the checks below.
If there are no signal bars or the phone shows SOS or No Service, network registration—not data routing—is the primary problem. Follow the no-service section in the general troubleshooting guide instead.
Select the Sri Lanka eSIM for Mobile Data
Dual-SIM phones can keep the home line active for calls while using the travel line for data. The eSIM may be enabled but not selected as the data source.
- Open the phone’s mobile network or cellular settings.
- Confirm that the Sri Lanka eSIM line is switched on.
- Open Mobile Data or Cellular Data.
- Select the Sri Lanka eSIM.
- Disable automatic mobile-data switching so the phone does not return to the home SIM.
For device-specific menu guidance, use the Sri Lanka eSIM for iPhone guide or the corresponding Android setup instructions in the Sri Lanka eSIM usage guide.
Turn On Data Roaming for the Travel eSIM
A travel eSIM normally connects through a roaming partner network, so data roaming must be enabled on the travel line. This does not mean that the home SIM must roam.
- Enable data roaming on the Sri Lanka eSIM.
- Keep the home SIM from using mobile data.
- If your home carrier charges for roaming calls or SMS, review its settings separately.
Check the APN
For a NoveSIM travel eSIM, the APN is data.esim. Do not enter a domestic operator’s APN or settings copied from another provider.
- Open the APN or Mobile Data Network menu for the travel eSIM.
- Enter data.esim in the APN field.
- Leave username and password empty unless your plan instructions explicitly say otherwise.
- Save the settings and make sure the new APN is selected.
- Return to the home screen and wait briefly before testing again.
See the full Sri Lanka eSIM APN guide if the APN menu is missing or the phone does not save the value.
Refresh the Data Connection Safely
- Turn on Airplane Mode for about 30 seconds.
- Turn Airplane Mode off and wait for the network name or signal bars.
- Keep Wi-Fi off during the test.
- Open a web page rather than relying only on an app notification.
- If necessary, restart the phone once.
Do not delete the eSIM. Many QR codes are intended for one installation, and deletion can make recovery more difficult.
Try Automatic and Manual Network Selection
Automatic network selection is the correct default. If data still fails, turn automatic selection off temporarily and wait for the available networks to appear. Select only a network listed in the plan instructions. After testing, return to automatic selection unless support advises otherwise.
Supported networks and 4G or 5G availability depend on the plan, device, location and local coverage. For the wider coverage context, see the Sri Lanka mobile-network guide.
Check Plan Status and Remaining Data
A phone can stay registered even when the plan has expired or its high-speed allowance has been used. Check the order details, validity period and remaining allowance in the relevant account or confirmation message. If the plan has not started when expected, confirm its activation policy rather than repeatedly changing settings.
When to Contact Support
Contact support when the correct data line, roaming and APN are confirmed but mobile data still does not work. Include the order reference, phone model, location, displayed network name and screenshots of the relevant settings. Do not send the full QR code publicly.

FAQ
Why does my Sri Lanka eSIM have signal but no internet?
The phone may be registered on a network while mobile data is assigned to the wrong SIM, data roaming is off or the APN is missing. Check those three settings first.
What APN should I use for a NoveSIM Sri Lanka eSIM?
Use data.esim. Leave username and password empty unless the plan instructions explicitly require other values.
Should I delete and reinstall the eSIM?
No. Keep the eSIM installed and contact support if the standard checks fail. Many eSIM QR codes cannot simply be reused after deletion.
Why does the internet work on Wi-Fi but not on the eSIM?
That confirms the app or website is reachable but does not prove the mobile-data line works. Turn off Wi-Fi and verify the selected data SIM, roaming and APN.
Final Recommendation
When a Sri Lanka eSIM has signal but no internet, begin with the data-line selection, data roaming and the data.esim APN.
Refresh the connection with Airplane Mode, test with Wi-Fi off and keep automatic network selection as the default.
Do not delete the installed eSIM. If the plan is valid and the settings are correct, send the phone model, location and screenshots to support for a targeted check.
