My iPhone has 2 numbers, both with eSIMs. My son has an iPhone with 1 number on an eSIM, and I want to transfer 1 of my numbers to my son, so I will end up with 1 number and he will have 2. I see videos on how to transfer, and it seems pretty easy, but how do I make sure I transfer the correct number? Does it let me pick? Do I need to set the number I am transferring as the primary so it knows to transfer that one?
