If a Mauritius eSIM is not working, first identify what the phone shows: no installed line, no signal, signal without internet, or a connection that is merely slow. Each symptom points to a different fix.
Most useful checks are reversible. Confirm the line assignment and roaming settings before changing the network or APN, and collect clear evidence before asking support to investigate.
NoveSIM plans are data-only, so the absence of a local phone number or ordinary calls and SMS is expected. Test with a website or map rather than a conventional call.
Quick answer: Keep the eSIM installed, select it for mobile data, enable Data Roaming on the travel line, disable automatic data switching, then use Airplane Mode briefly. Edit the APN only when the phone has signal but no data and the supplied instructions require data.esim.

Start with the Symptom on the Screen
| Symptom | Likely layer | First action |
|---|---|---|
| No travel line in settings | Installation | Check whether the profile finished installing |
| Travel line present but no signal | Network registration | Check line status and roaming; refresh registration |
| Signal bars but websites fail | Data routing or APN | Confirm the data line before checking APN |
| Internet works but is slow | Coverage, congestion or device load | Change location and stop heavy background use |
If the eSIM Does Not Appear
Open Cellular, Mobile Service, Network & Internet or SIM Manager and look for the label chosen during installation. If it is absent, do not repeatedly scan the QR code. Reopen the order instructions on private Wi-Fi and compare the phone with the compatible-device list.
A carrier-locked handset may refuse another provider’s profile even when the model supports eSIM. The original carrier must resolve that restriction. If the installation began but did not finish, follow the Mauritius installation guide or contact support before another attempt.
If There Is No Signal
- Confirm that the Mauritius line is switched on.
- Select it as the mobile-data line.
- Enable Data Roaming on that line and keep roaming off on the home line.
- Turn off automatic cellular-data switching.
- Leave network selection on Automatic.
- Enable Airplane Mode for about 30 seconds, turn it off, and allow several minutes for registration.
- Restart the phone once if the status does not change.
Test outdoors or beside a window if the problem occurs deep inside a terminal or concrete building. Compatibility does not guarantee reception in every indoor space. For realistic location expectations, use the Mauritius coverage guide.
If Signal Appears but Mobile Data Does Not
Switch Wi-Fi off temporarily so the test uses cellular data, then open a simple webpage. Verify that the travel line—not the home SIM—is assigned to mobile data and that the plan still has usable allowance and validity.
Only then inspect the APN. NoveSIM’s manual APN is data.esim; username and password remain blank unless the order instructions explicitly say otherwise. Save and select the entry after editing. The dedicated Mauritius APN reference gives the iPhone and Android paths.
If the Connection Is Slow Rather Than Broken
- Move away from the centre of a large building and test again.
- Stop cloud backup, app updates, video streaming and other background transfers.
- Disconnect hotspot clients and test on the phone alone.
- Keep preferred network mode automatic; stable 4G can outperform weak 5G.
- Compare results in another location and at another time before treating it as a configuration failure.
APN editing does not improve congestion or weak radio signal. If data works, preserve the settings and gather the location, time, displayed network type and result of two simple tests.
What to Send NoveSIM Support
Contact NoveSIM Support with the order number, exact phone model, current location, whether signal bars appear, which line is selected for data, and safe screenshots that do not expose the QR code or activation details. Explain which reversible steps were completed.
Do not delete or remove the installed eSIM unless support explicitly instructs you to do so. Some activation codes are intended for one installation, so deletion can turn a connection problem into a reinstall problem.

FAQ
Why does my Mauritius eSIM show signal but no internet?
The wrong line may be selected for data, roaming may be off, the allowance may be exhausted or the APN may be missing. Check those items in that order.
Should I choose a network manually?
Automatic selection is the default. A manual scan is a later diagnostic step; try only networks offered by the phone and return to Automatic after the test.
Should I delete the eSIM and scan the code again?
No. Keep the profile installed and contact NoveSIM Support before removal, because the activation code may not permit another installation.
Final Recommendation
Diagnose the displayed symptom instead of changing every setting at once.
Start with line selection, roaming and network refresh; use data.esim only for a relevant signal-without-data problem.
Preserve the installed profile and send precise evidence to support if the reversible checks do not restore service.
