i have a Iphone X and 7+ that I’m trading in after purchasing the Pro and Pro Max. Obviously it’s been awhile since I’ve traded anything in to Verizon. Can anyone explain what needs to be done to these phones before I mail them back to VZ? I know I have to turn off Find My, but do I need to do anything else? The sales person I dealt with at the store at the time of purchasing the new phones was not helpful in answering this question. Thanks a bunch!
