Gemplus International has renewed its multi-year supply agreement with Cingular Wireless, the largest wireless carrier in the United States, for Subscriber Identity Module (SIM) cards and was selected as one of Cingular’s primary suppliers of Universal SIM (USIM) cards. Cingular is currently using Gemplus’s SIM cards for Enhanced Network Selection and advanced data services for its GSM subscribers. More than 75 million North Americans use SIM cards today. This number is expected to increase significantly over the next few years as more and more operators continue to migrate their subscribers to SIM cards. The (U)SIM card authenticates and identifies individual subscribers onto the wireless network and lets wireless carriers have a one-to-one relationship with subscribers.  (U)SIM cards enable subscribers to freely carry their subscription and personal information from phone to phone.
