Hello RedQ5-RedSE,
We understand that you're experiencing an issue setting up eSIM, and we want to help.
"iPhone XS, iPhone XS Max, iPhone XR, and later feature Dual SIM with a nano-SIM and an eSIM. An eSIM is a digital SIM that allows you to activate a cellular plan from your carrier without having to use a physical nano-SIM."
Just to confirm, did you have a chance to go through the steps outlined in the "If you can't set up your eSIM" part of the link you came from? If so, did those steps seem to improve the issue at all?
Are you using the steps outlined in the "Scan a QR code" section of the following page to scan the QR code your carrier provided? Using Dual SIM with an eSIM
Thank you!
