eSIM for new iPhone Duo

Hello
I’m looking at getting the new iPhone Duo due to be released in the UK in October. I currently have a Lebara physical SIM card in my older iPhone. I’m trying to understand how I transfer my plan to an eSIM for the new Duo? When I try to do this, the Duo isn’t available to select. (Nor is the new iPhone 18). Any guidance?

If you're currently on a physical SIM then I think the best approach would be to wait until you have the new iPhone Duo in your hands and then switch to eSIM using the usual process. Remember to confirm that the device is on the compatible devices drop down list before you proceed.
