What this part is
The SIM tray slides into the edge of the Galaxy S23 Ultra and holds the SIM card against the reader. A bent or cracked tray can scratch the reader, stop the SIM being detected or let dust and water in.
This dual SIM tray is made for the Galaxy S23 Ultra and comes in several colours, so you can match your phone. It holds two nano-SIM cards.

How to check your model
Open Settings › About phone. The name should read Galaxy S23 Ultra, and the model number should start SM-S918B (a /DS ending just means dual SIM). The model number is also on the box.
The Galaxy S23 Ultra has a 6.8-inch screen and a built-in S Pen. It looks close to the S22 Ultra and S24 Ultra, but the internal parts differ.
Professional installation
How a technician fits this part
- Power the phone off.
- Push a SIM ejector pin into the small hole beside the tray and pull the old tray out.
- Check the slot for bent pins or debris. Do not push anything into it.
- Place the SIM card in the new tray, gold contacts facing down.
- Slide the tray in straight until it sits flush with the frame.
- Power on and check that the SIM and signal are detected.
Check that the part matches the device before fitting it or removing any adhesive backing. Once a part has been fitted, it cannot be returned for a change of mind. Faulty parts are always covered.
