A subscriber identity module (SIM) card connector that can be embedded within a mobile communication device is provided. The SIM card connector comprises a body having an accommodating space for disposing a SIM card and multiple connected-through receptacles for receiving conducting terminals. Through the conducting terminals, an electrical signaling contact with the SIM card can be made. The connector further includes a guide arm having a first salient block and a second salient block. The first salient block and the second salient block are disposed on the respective sides of the guide arm and a cover is connected to the body for covering the accommodating space. Furthermore, the cover may connect with the guide arm through a pivot. The cover further comprises a groove. When the second salient block is moved, the first salient block shifts inside the groove and push the SIM card out from the accommodating space.
