Overview
What this part is
The Galaxy A31 tray slides into the side of the phone and holds your SIM card and a microSD memory card. A bent or cracked tray can stop the phone reading the SIM, leave a gap in the frame or let dust into the slot.
This tray is shaped for the Galaxy A31 slot, so it sits flush with the frame. Fitting takes seconds: push the ejector pin into the small hole, pull the old tray out and slide the new one in.
