An improved SIM card reader with at least one reader data contact that is connected, typically through a control unit, to a memory, through which reader data contact predetermined software update data may be transmitted for storage in the memory of a mobile telecommunication device. The SIM card reader may be integral to the mobile communication device. In a preferred embodiment, the SIM card reader receives an improved SIM card having a card data contact that cooperatively engages with the reader data contact to electrically couple the reader data contact and the card data contact, thereby to provide a data path through which software update data may be transmitted for storage in the memory of a mobile telecommunication device. The at least one reader data contact may be used to "flash" the memory of a mobile telecommunication device with software updates, for instance. Additional reader data contacts may be implemented for testing functions, such as, for instance, Received Signal Strength Indication (RSSI), transmission power confirmation, VCO Frequency confirmation, and power level.
