I plan on buying an iPhone 12 through Swappa (link attached) My carrier is Visible I am in their Premium Plan. Is there anything I should know before I buy? I really want the iPhone 12 because I’ve never had a big screen iPhone before (I have iPhone SE 2020 currently) and also I would like a 5G capable device. Thanks!
