Nope. "Add a sim" enables you to scan a QR code from your provider only, no option to convert a physical sim. Samsung has had this feature for years. Despite rumours in advance of launch, it appears as if Google still don't offer this option.
Has anybody succeeded in convering a Physical sim to esim on Android 14? This was a much publicised feature pre-launch, but having just received my Pixel 8 Pro, I cannot find an option anywhere in settings to do the conversion.
