dual eSIM for iPhone12?
I have an iPhone 12 running iOS 16.7.2. I have been using it with one eSIM carrier in my home country in Europe (MEO), and one SIM in the US (T-Mobile). I want to add another carrier to use in another country in Europe (probably Orange, to use in France) and I want to keep that first eSIM with MEO but I would not use it much - maybe once a month, or even less. I have read that one can HAVE two eSIMs on an iPhone 12, but only one ACTIVE (along with the regular SIM). What is required to switch between eSIMs? Would MEO get confused if I didn't have that eSIM on for, say, months at a time? The thing is, certain activities in each of these European countries (France and Portugal) require one to have a "local" phone number. And I want to keep my US number.
iPhone 12, iOS 16
