Description / Function

• The SIM tray is a small metal or plastic holder that slides into a slot in the phone. It is designed to securely hold SIM cards so they can connect to the mobile network.

• The OnePlus 7T uses a dual-SIM tray—i.e. it can carry two nano-SIM cards at once. Witrigs+2XDA Forums+2

• The tray is inserted and ejected from the bottom edge (or sometimes the side, depending on model variant) using a SIM-eject (pin) tool. Three

• The tray has precisely cut slots/grooves to align and secure the SIM cards so their contact pads touch the internal SIM reader pins inside the phone.

• It also often includes a gasket or seal (in many phones) to help maintain the device’s water/dust resistance (though that depends on the overall design and sealing of the phone body).
