Guys a simple question, what is a SIM card? john_pederson 15-April-2008 08:45:49 PMComments SIM (Subscriber identity module) is basically inside your mobile station. Posted by Hash007 Ans 1) A SIM (subscriber identification module) card is a card that identifies the user of a wireless system. SIM cards are currently used with GSMs. The SIM card contains subscriber information that enables a subscriber to utilize different handsets when they travel from market to market or country to country. The SIM card comes in several sizes ranging from a small chip to a credit card, both of which fit into the subscriber unit itself. Ans 2) Subscriber Identity Module (SIM) is part of a removable smart card ICC (Integrated Circuit Card), also known as SIM Cards, for mobile cellular telephony devices such as mobile computers and mobile phones. SIM cards securely store the service-subscriber key (IMSI) used to identify a subscriber. The SIM card allows users to change phones by simply removing the SIM card from one mobile phone and inserting it into another mobile phone or broadband telephony device. SIM cards are available in two standard sizes. The first is the size of a credit card (85.60 mm × 53.98 mm x 0.76 mm). The newer, more popular miniature-version has a width of 25 mm, a height of 15 mm, and a thickness of 0.76 mm. However most SIM cards are supplied as a full-sized card with the smaller card held in place by a few plastic links and can be easily broken off to be used in a phone that uses the smaller SIM.
