Activation of Esim

If you are adding a new eSim to an existing iPhone you do so by transferring it from another iPhone or via a QR code from your service provider as shown in the screenshots you posted.

You need to request an eSim QR code from your provider if you want to add one to your iPhone.

Alternatively you can convert an existing physical SIM card on your iPhone to an eSim if you want to and your carrier supports it, by following the steps here -> About eSIM on iPhone - convert SIM card to eSim - Apple Support

What are you trying to accomplish exactly?

Are you trying to add a new number, different to the one you already have, or are you trying to convert your existing number and its physical SIM card to an eSim?

There are three main methods to activate the embedded SIM (eSIM) on an iPhone.

The first method is carrier activation, which involves following on-screen instructions during initial iPhone setup to activate the eSIM with your wireless carrier.

The second method is quick transfer, which allows you to move an existing physical SIM or eSIM number from another iPhone onto the eSIM of your new iPhone 14.

The third method is to scan a QR code or use your carrier’s app to activate a prepaid or travel eSIM plan. Major carriers like AT&T, T-Mobile and Verizon all support eSIM activation on iPhone.

Here's a step-by-step guide on how to install and activate eSIM on iPhone.
