I recently did this with a 5ber esim adapter, which is similar to esim.me, and it works with the PM esim. The only problem is you need still need a phone that supports esim to activate the subscription with the public mobile app first. Then it will generate the QR code email which you can scan with the non-sim phone and adapter. The app checks if your device is esim compatible and won't let you activate if it detects your phone is not esim compatible but you selected esim. So just be careful about that. Not sure if it's the same thing if you already have an active subscription and changing to esim.
