Tracking iPhone after switching SIM card
This weekend I am proposing to my girlfriend. She thinks I have to stay in another city for work, and I don't want her to know I'm headed her direction. If I swap the SIM card to one of my old iPhones (6s) and leave the current phone (X) at my house in the other city connected to wifi, will it show her the location of my X (SIM card getting removed) in Find My Friends or the location of the 6s (phone I can put the SIM card in)?
iPhone X, iOS 13
