In CDMA (Code Division Multiple Access) technology, a SIM card is not required because the identification and authentication of the mobile device are managed through the device's unique ESN (Electronic Serial Number) or MEID (Mobile Equipment Identifier). This allows the network to recognize and authenticate the device directly, eliminating the need for a removable SIM card. Additionally, CDMA networks store subscriber information on the network side rather than on a physical card, which simplifies the device's design.
