Yes, your primary number should be able to receive calls if your device allows you to activate a SIM card and e-SIM card at the same time.
If you're using an iPhone, select models have Dual SIM Dual Standby (DSDS) technology that allows you to stay connected to both your physical SIM card and your eSIM at the same time.
However, the number of eSIMs you can have active on your device depends on the device model. So check carefully how many eSIMs your phone can support.
For more information, please contact the manufacturer of your device.
Also note that data roaming charges may apply to calling service depending on your carrier.
