Greetings! I have a FamilyCard in my iPhone and through Apple Family Setup I set up an e-sim for the children in their AppleWatch SE from my phone. I was told by Vodafone that roaming in this option will not work in AppleWatch. Therefore, I want to buy phones for my children, put physical SIM cards in the phones and activate e-SIM in the watches from their phones, enable roaming. What is needed for this? Do I need to order another number and SIM or can I keep the phone number and just order a physical one with the same number? What is the sequence of actions? And will roaming in AppleWatch without a phone work after these manipulations?
