On iPhone, a Mauritius eSIM should be labelled clearly, selected under Cellular Data and allowed to roam on its own line when required. Automatic cellular-data switching should remain off.
This page maps the Apple controls after compatibility and installation have already been understood. It does not replace the complete plan-specific installation and activation instructions.
NoveSIM travel plans are data-only, so they do not add a Mauritian number or ordinary calls and SMS. The primary line can remain available separately, subject to its carrier’s roaming charges.
Quick answer: Open Settings → Cellular or Mobile Service, switch the Mauritius line on, select it under Cellular Data, disable Allow Cellular Data Switching and enable Data Roaming for the travel line. Test with Wi-Fi off.
Top Mauritius eSIMs
Confirm This iPhone Can Use the Plan
- The exact regional model includes eSIM support.
- Add eSIM appears under Cellular or Mobile Service.
- Carrier Lock in Settings → General → About shows no SIM restrictions.
- The selected plan explicitly includes Mauritius.
Use the full Mauritius compatibility guide if any check is uncertain. An Apple family name alone does not prove that every regional variant is eligible.
Add and Label the Travel Line
- Connect to dependable private Wi-Fi.
- Open Settings and Cellular or Mobile Service.
- Tap Add eSIM and use the private QR code or supplied manual details.
- Wait for the profile to appear before leaving settings.
- Label it “Mauritius” or “Travel Data”.
Protect the QR code and do not scan it repeatedly. The canonical Mauritius eSIM installation guide explains timing, security and the difference between installation and activation.
Assign Data Without Moving Calls
- Open Cellular Data and choose the Mauritius line.
- Turn Allow Cellular Data Switching off.
- Open the Mauritius line and enable Data Roaming when instructed.
- Open the home line and keep its Data Roaming off.
- Leave the desired home line as Default Voice Line if you want it available for calls and SMS.
Receiving or making calls on the home number may cost extra. Read the home carrier’s roaming terms and use the dual-SIM assignment guide before leaving both lines active.
Test the Correct Line After Arrival
Turn Wi-Fi off and open a simple webpage. The cellular-data indicator should belong to the Mauritius line. If the profile has only just been enabled, allow several minutes for registration before using Airplane Mode briefly or restarting once.
Follow the Mauritius activation sequence for the full arrival handover. Do not use an ordinary telephone call as the data test.
If the iPhone Has Signal but No Data
- Reconfirm the selected Cellular Data line.
- Check Data Roaming on the travel profile.
- Verify remaining allowance and validity.
- Only when relevant, inspect Cellular Data Network for the NoveSIM APN data.esim.
Some iPhones do not expose manual APN editing because the profile manages it. Do not reset all network settings simply to reveal the field. Use the Mauritius APN reference or contact NoveSIM Support.
Keep the installed eSIM in place during troubleshooting. Removal may make a single-use code unavailable.

FAQ
Where is Add eSIM on iPhone?
Open Settings and Cellular or Mobile Service. If Add eSIM is absent, check the exact regional model and carrier restrictions.
Can my home number stay active?
Yes on a compatible dual-line setup, but calls, SMS and voicemail activity can be charged by the home carrier.
Should Allow Cellular Data Switching be on?
No. Keep it off to reduce the risk that the iPhone moves data to the home line when travel coverage weakens.
Final Recommendation
Use this page to locate Apple’s line controls after eligibility and installation are confirmed.
Assign Mauritius to Cellular Data, restrict roaming to that line and keep automatic switching off.
Test without Wi-Fi, preserve the installed profile and use the canonical installation or troubleshooting guide for the next task.
