What do the letters SIM stand for in reference to a cell phone sim card?
Why do some carriers use sim cards and others don't? Cingular,T.Mobile and Nextel do,verizon doesn't. What exactly do they do?
A Subscriber Identity Module is a smart card roughly the size of a postage stamp that securely stores the key identifying a mobile phone service subscriber, as well as subscription information, saved telephone numbers, preferences, text messages and other information. The equivalent of a SIM in UMTS is a Universal Subscriber Identity Module (USIM).
Sim cards are used by all GSM providers (Tmobile, Cingular, many others worldwide). If I take out my SIM card and put it into any other unlocked GSM phone that phone becomes my number instantly...no need to activate or transfer contacts etc.
