Third generation, or IMT-2000, is a set of standards outlining the operation of new mobile phones. Three-G typically offers increased rates of transmission, when compared to its predecessors, 2G, 2.5G and 2.75G. The implementation of 3G standards called for an increase in performance that slightly older handsets were still capable of, and some 3G-ready handsets, such as the iPhone, were released before the 3G service could be rolled out on its carriers, requiring an activation procedure to unlock their full potential. Typically, older handsets require that you obtain a 3G SIM card before accessing 3G service.
