What type of smartphones typically use a SIM card for network identification?

• A. GSM smartphones
• B. CDMA smartphones
• C. Feature phones
• D. Smart speakers

Answer: (A)

GSM smartphones are designed to utilize SIM cards for network identification. The SIM card, which stands for Subscriber Identity Module, stores the International Mobile Subscriber Identity (IMSI) and other essential data that authenticate the user on the mobile network. This system allows users to easily switch devices by simply transferring their SIM card to another compatible GSM phone without losing their number or settings. In contrast, CDMA smartphones generally do not use SIM cards for network identification. Instead, they rely on the device's electronic serial number (ESN) for service authentication with the network. Feature phones may or may not use SIM cards, depending on whether they are based on GSM or CDMA technology. Smart speakers, typically designed for smart home integration and voice assistance, do not use SIM cards, as they primarily rely on Wi-Fi or other internet connections rather than cellular networks. Therefore, the distinctive feature of GSM smartphones using SIM cards makes it the correct answer to the question regarding smartphones that typically utilize SIM cards for network identification.
