To activate an already installed Mauritius eSIM, switch the travel line on, select it for mobile data and enable Data Roaming on that line when the plan instructions require it. Keep the home line from taking over data.
Activation is the arrival handover between an installed profile and a usable local connection. It is not the same as scanning the QR code, and the event that starts validity depends on the specific plan.
NoveSIM travel plans are data-only. Test them with a webpage or map rather than an ordinary telephone call, because they do not provide a Mauritian number or traditional calls and SMS.
Quick answer: Read the plan’s activation rule, turn the Mauritius profile on, assign it to mobile data, enable roaming for that line, disable automatic data switching and test with Wi-Fi off. Allow several minutes for first registration.

Confirm That Installation Is Complete
Open SIM, Cellular or Mobile Service settings and look for the label chosen during installation. The line should be present before any arrival activation steps begin. If it is missing, return to the Mauritius installation guide; do not repeatedly rescan the code.
Check the current plan terms for the activation trigger. Some plans begin on first connection to a supported network, while others may use a different rule. The order instructions—not a generic travel assumption—are authoritative.
Use This Arrival Sequence
- Turn the Mauritius eSIM line on.
- Select it as the phone’s mobile-data line.
- Enable Data Roaming on the travel line if instructed.
- Keep Data Roaming off on the home line.
- Disable automatic or adaptive cellular-data switching.
- Leave network selection on Automatic.
- Turn Wi-Fi off temporarily and wait several minutes for registration.
- Open a simple webpage and refresh a map to confirm usable data.
At Sir Seewoosagur Ramgoolam International Airport, use verified terminal internet only if a final instruction must be retrieved. The Mauritius Airport arrival guide covers the transition from terminal Wi-Fi to onward mobile data.
Activation on iPhone
Open Settings, then Cellular or Mobile Service. Select the Mauritius line and switch it on. Under Cellular Data, choose that line and turn Allow Cellular Data Switching off. Enable Data Roaming inside the travel-line settings when required.
The home number can remain active for calls or SMS, but home-carrier roaming charges may apply. The Mauritius dual-SIM assignment guide separates voice, messaging and data choices.
Activation on Android
Look in SIM Manager, Network & Internet, Connections or Mobile Network. Enable the downloaded profile, set it as the preferred data SIM, turn its roaming on when instructed and disable automatic data switching.
Manufacturer labels differ, so use the settings search if necessary. Do not change unrelated APN, authentication or radio settings merely because another phone shows different menus.
How to Verify That Activation Worked
- The travel line shows a network name or signal indicator.
- A webpage loads while Wi-Fi is disabled.
- The mobile-data indicator belongs to the Mauritius line.
- The home line is not consuming roaming data.
- The plan dashboard or balance reflects a valid active state where available.
Signal bars alone do not prove that data works. Conversely, a short first-registration delay does not mean the profile has failed. Give the handset time to attach before restarting it once.
If the Line Does Not Come Online
- Recheck that the travel line—not the home SIM—is assigned to data.
- Confirm roaming on the travel line and off on the home line.
- Use Airplane Mode for about 30 seconds, then wait for registration.
- Restart the phone once.
- If signal appears without data, verify allowance and then check the NoveSIM APN data.esim.
Use the Mauritius troubleshooting guide to diagnose the displayed symptom or the APN reference for exact fields. Do not delete the installed eSIM. Contact NoveSIM Support before removal.

FAQ
When should I activate my Mauritius eSIM?
Follow the specific plan’s activation rule. Prepare installation before travel when permitted, then complete the data-line and roaming handover at the instructed time.
Why must Data Roaming be on?
A travel eSIM may connect through a partner network and need roaming enabled on its own line. Keep roaming off on the home SIM unless intentionally used.
Does seeing signal mean activation is complete?
Not by itself. Disable Wi-Fi and load a webpage to prove that the travel line has a working data session.
Final Recommendation
Begin with a confirmed installed profile and the plan-specific activation terms.
Assign the Mauritius line to data, enable its roaming, disable automatic switching and test without Wi-Fi.
If service does not start, use reversible checks, preserve the profile and escalate with precise evidence.
