My iPhone 11 Pro Max on iOS 16.3 doeS not allowed me to Add Esim. The iPhone 11 has a physical sim. I was able to do this (add Esim for traveling purposes) on Nov 2022 not sure iOS is that. Keep getting this message. Any help appreciated

Remove the SIM card from your device then use reset all settings. open>settings>general>scrolldown, your general screen then>transfer or Reset iPhone and click reset all settings. Then register Esimcard when you activate it (Esimcard) try to put your old SIM card back in your device when you make sure Esim card is active. I hope this information helps you.
Transfer a physical SIM or eSIM on your previous iPhone to an eSIM on your new iPhone after setup
The problem had been fixed. Thanks - not iOS 16.3 problem
