Product Description

SIM cards are used with carriers that operate on the GlobalSystem for Mobile Communication network.

The competing network is Code Division Multiple Access, atechnology created by U.S. company Qualcomm.

As of fall 2005, CDMA cell phones and CDMA carriers do notsupport SIM cards in most parts of the world, though this ischanging .A CDMA SIM card called the R-UIM (Re-useableIdentification Module) was made available in china in 2002, andwill eventually be available worldwide.

Expectations for the future include a cell phone market thatsupports both SIM (GSM) and R-UIM(CDMA) cards by default.
