Hello all. I currently have a iPhone 13 Pro Max that isn’t due for an upgrade until next year. My wife’s phone was due for an upgrade (coming from an iPhone 11). The new phone will be here tomorrow. Is there a way to make her phone number on the 13 pro max and my telephone number on the 15 pro max without going to AT&T? I am just trying to save myself the trip, I know they can do it at the store.
