SIM cards
Mobile identity chips
SIM cards are small chips that store subscriber information for mobile phones, identifying the device to a cellular network.
The acronym stands for Subscriber Identity Module.
Swapping a SIM card between phones transfers your phone number and service: I popped my SIM card into the new phone.
Modern eSIMs are embedded and don't require physical cards.
