Wi-Fi Calling does not normally deactivate an eSIM. It changes how supported calls reach an operator, while mobile data selection remains a separate setting.
If internet stopped after enabling it, check whether the phone joined weak Wi-Fi, changed the preferred SIM or lost mobile network registration.
Keep the eSIM installed and test data independently from calls.
Quick answer: Turn Wi-Fi off, test a webpage and confirm the travel eSIM is selected for mobile data. If data works, investigate Wi-Fi Calling on the primary line; if not, refresh roaming and network registration.
Separate calls from data
NoveSIM plans are data-only, so Wi-Fi Calling for a conventional number belongs to the home operator. Its availability and charges depend on that operator.
Review how data-only eSIMs and phone numbers differ.
Run a clean mobile-data test
- Turn Wi-Fi off.
- Select the travel eSIM for mobile data.
- Disable automatic data switching.
- Load a webpage.
- Toggle airplane mode once if it fails.
Check line and network settings
Enable the required roaming setting and leave operator selection automatic. For manual NoveSIM APN use data.esim.
Use the SIM switching guide and no-internet checks.

FAQ
Does Wi-Fi Calling use the travel eSIM?
It may use an internet connection, but the call service and charges belong to the operator providing the number.
Can Wi-Fi Calling delete an eSIM?
No. It does not normally remove a cellular profile.
Why does data work when Wi-Fi is off?
The Wi-Fi network may lack internet or interfere with routing while the eSIM itself works.
Should I reinstall the eSIM?
No. Test call routing and mobile data separately.
Final Recommendation
Diagnose Wi-Fi Calling and travel data as separate services.
Confirm the eSIM data line with Wi-Fi off, then adjust the home operator’s calling feature if necessary.
