best price i can get right now for a 13PM is between $570 (trade in to Apple) - &700 (sale privately). 13PM being the last U.S. spec iphone that still has a sim card slot makes me want to hold onto it, in case i go to another country that has issue with esim, other than that, i have no other use for it. the value for 13PM will go down drastically when this trading in for phone 15 wave passes by. should i keep or get rid of the 13PM?
