iPhone 12 on iOS 18.2.1 using an e-SIM on one line and a physical SIM on the other. Inhave both lines turned on, but the physical SIM selected as the default phone line.

In spite of the physical SIM line being selected as default line, the phone always rings out on the e-SIM line.

How do I force the phone to ring out on the default line?

It will ring out on the Physical SIM line if I the other line off, but I want them both on for incoming calls.

Those are all of your phone carrier features, contact yours.

Contact your carrier as they are the ones in charge of your SIM.

I understand that each card represents one different number, so if there is a call on one number, You will receive the ring on the called number regardless the card is physical or electronic.

If this is not working properly, the mobile carrier company can fix this point for you.

It is not a problem with the SIM, it is a phone issue. You select the SIM you want to be default for phone calls on the phone, which is what I have done, but it doesn’t use that SIM unless I turn off the line for the other one.

Is that what your phone carrier told you when you contacted them about your issue. Again as stated ALL of those are your phone carrier features not Apples.
