Overview
What this part is
When you push the SIM tray into the iPhone XS Max, the SIM touches a small reader socket on the main board. Bent pins, corrosion or a tray forced in the wrong way round can make the phone lose the SIM or show No SIM.
Before you buy, try another SIM card and check the tray is not bent. This socket is soldered to the logic board, so fitting needs micro-soldering tools and experience. It is not a job for a first repair.
