Samsung Galaxy S25+ Sim Connector

1. SIM Card Connector

• Function: This is the actual electronic component located on the main board (or a sub-board like the charging port board) that physically makes contact with and reads the SIM card chip.
• When you need it: If your phone does not recognize a SIM card, gives a “No SIM Card” error, or loses signal when the SIM is known to be good.
• Repair Note: Replacing this part is complex and often involves micro-soldering onto the main board. It is a repair best left to highly experienced technicians. In some models, the SIM reader is integrated with the charging port flex cable, making replacement slightly easier but still requiring internal disassembly.

2. SIM Card Tray (External Component)

• Function: This is the small, removable plastic or metal tray that holds the Nano-SIM card (and sometimes a second SIM or a microSD card, depending on the model/region) and slides into the side of the phone.
• When you need it: If the original tray is lost, bent, broken, or has a damaged water-resistant gasket.
• Repair Note: This is the easiest and most common SIM-related replacement. You simply need the correct replacement tray in the corresponding phone color. The S25+ typically uses a Dual SIM tray in certain regions, which holds two Nano-SIM cards, one on each side.²
