The voice line and the mobile-data line are separate choices on a dual-SIM phone. Start by identifying which SIM owns the telephone number and which one is selected for data, then check dual-SIM standby and the default voice line.
The safest approach is to label both lines, make the choice deliberately and test the result before travel. This guide covers dual-SIM standby, the default voice line, Wi-Fi Calling without assuming that every iPhone or Android menu uses the same wording.
A NoveSIM travel plan supplies mobile data, not a local telephone number or a bundle of carrier calls and texts. Internet calling and chat apps can use that data; conventional calls and SMS still belong to the primary operator.
Quick answer: Yes, a compatible dual-SIM phone can usually receive calls on the primary number while a travel eSIM supplies mobile data. The primary carrier may still charge for incoming calls, outgoing calls, voicemail or call forwarding while roaming.
Keep the Number-Owning Line Enabled
The primary SIM must remain enabled and registered if ordinary carrier calls need to reach its number. Choosing the eSIM for Mobile Data does not transfer the telephone number to that eSIM, and a data-only NoveSIM plan does not receive traditional calls itself. Check the current NoveSIM destinations and plans before relying on coverage.
Set Mobile Data without Changing Voice
On iPhone, choose the travel eSIM under Cellular Data while retaining the preferred voice line. On Android, select the eSIM for mobile data in SIM Manager and review the Calls preference separately. Disable automatic data switching to prevent the primary SIM from taking over data. See keeping the primary number with eSIM data.
Understand Roaming and Voicemail Charges
The home carrier controls the cost of incoming calls, outgoing calls, voicemail retrieval and conditional call forwarding abroad. Wi-Fi Calling can behave differently by carrier and location, so confirm its terms before relying on it as a free alternative. Review Data Roaming for a travel eSIM before changing that switch.
Test Both Functions Independently
Open a website to confirm that data uses the travel line, then place a short test call to the primary number if its roaming cost is acceptable. A working data session does not prove that the voice line is registered, and a visible signal does not prove that calls are free. Use the device compatibility checks when the handset variant is uncertain.
Check iPhone and Android Separately
On iPhone, review Cellular settings, Default Voice Line and Cellular Data. On Android, use SIM Manager or the manufacturer’s equivalent. Menu names vary, so follow the labels visible on the exact phone rather than a generic SIM 1 assumption. iPhone users can follow the iPhone installation steps.
Name Each SIM before Changing Settings
Use clear labels such as Primary and Travel. Confirm which line owns the usual number and which line supplies mobile data; the default voice, message and data choices are separate controls.
Practical Checklist: Can I Receive Calls While Using eSIM Data
Check dual-SIM standby first, then confirm the default voice line before relying on the result for an essential transfer, payment or verification message. The conclusion should match what the phone and current plan actually show.
A Safe Final Connection Check
- Confirm that the travel eSIM is still visible and enabled.
- Select it for Mobile Data without changing the voice line by accident.
- Turn on Data Roaming for the travel line and turn off automatic data switching.
- Wait for Automatic Network Selection before testing a normal website.
- Enter data.esim only when the NoveSIM instructions require a manual APN.
If the result is still wrong, keep the installed eSIM and record the device model, present location, selected lines and visible network status. Support can work from the device and network evidence; the installation QR code should remain private. Remove the profile only if Support explicitly requests that step.
