Wi-Fi Calling with an eSIM can work, but the answer depends on which line owns the telephone number. A data-only travel eSIM supplies internet access; it does not add ordinary voice service to that travel line.
The home carrier must support Wi-Fi Calling for the primary number, the phone must support the relevant dual-SIM behaviour and the feature often needs to be enabled before leaving the home network.
NoveSIM travel eSIMs provide data without a new telephone number, conventional calls or carrier SMS.
Quick answer: It can. The home line may use Wi-Fi Calling while a travel eSIM supplies the internet connection, but the feature depends on the phone, home carrier and account configuration. Enable and test it before departure, keep the correct voice line selected and confirm how the carrier bills calls made abroad.

Check the phone on the compatible-device list, review how NoveSIM works and compare plans under travel destinations.
Two Lines Perform Different Jobs
In a dual-SIM setup, the primary line can retain its number while the travel eSIM handles mobile data. Wi-Fi Calling belongs to the primary carrier account. Labels such as Primary and Travel are only names; verify which line is selected for calls and data.
How Wi-Fi Calling with an eSIM uses travel data
Some phones and carriers allow the primary line to use the second line’s cellular data as if it were Wi-Fi. Apple may describe this through the carrier name followed by “using Cellular Data”. Availability depends on device, operating system and carrier configuration.
If this behaviour is essential, confirm it with the home carrier. A NoveSIM data plan cannot enable a voice feature that the primary carrier blocks.
Set Up before Departure
- Enable Wi-Fi Calling on the home network and complete any required emergency-address step.
- Make a test call on dependable Wi-Fi.
- Install the travel eSIM according to its activation timing.
- At the destination, select the travel eSIM for Mobile Data.
- Disable data roaming on the home line and automatic data switching when cost control matters.
Calls May Still Be Chargeable
Wi-Fi Calling does not automatically make every international call free. Billing depends on the home carrier, the number called and the tariff. Check calls to home-country, destination and premium numbers separately.
FAQ
Does a data-only eSIM include Wi-Fi Calling?
No. It supplies data. Wi-Fi Calling for an existing number is a feature of the carrier that owns that number.
Can I receive SMS while the travel eSIM provides data?
The home line may receive SMS if it remains active and registered, but availability and charges depend on the home carrier.
Why did Wi-Fi Calling disappear abroad?
The carrier may restrict it, the line may not be registered, or the phone may not support using the second SIM’s data. Recheck the home line and carrier terms.
Should Data Roaming be enabled on both lines?
Enable it on the NoveSIM travel line. Keep it off on the home line unless you intentionally accept the home carrier’s roaming charges.
Final Recommendation
Treat Wi-Fi Calling with an eSIM and travel data as separate services. Test the primary carrier’s calling feature before departure, then configure the travel eSIM solely as the mobile-data line.
Confirm call charges and keep a backup internet-calling app. This avoids relying on a feature that may vary by carrier, device or destination.
