I talked to two AT&T employees today, at the store. They both said if you have a iPhone 13 with a physical SIM card, that when you did the data transfer to the iPhone 14, it will move your service onto the 14 eSIM. They have already witnessed it as they said the last batch of iPhone 13, they received, did not have a SIM tray And the transfer works perfectly.
I know many are hating to loss of the physical SIM but it is what is going to be in the future. It is the first step to control over our phones by big brother. One day our phones will,have to be registered to get on the Internet or make calls. 😫
