A SIM card is a microchip card used in cell phones to carry specific transmission information and personal phone data. The SIM card is needed to use the cell phone in any regard, except to call 911 in an emergency. To protect the data and information on the card, the SIM may carry a pin code password. While some service providers let you set your own pin password, others will program a predetermined code onto the SIM so it is protected at all times. Use your cell phone to remove the pin code from your SIM card.
