I live in US and currently have a 14 Pro Max with two eSIMS - one T-Mobile in US and another Airtel from India. I just got the 15 Pro Max and I know the T-Mobile eSIM plan will transfer effortlessly to my new iPhone, but the Airtel from India won't. They have a different process, which I can do, but will it cause an issue when i do phone to phone transfer when I get the new one? Anyone know how that will work?
