SIM card
Cellular identity module
A SIM card is a small chip inserted into a mobile phone that identifies the user to the cellular network.
It stores subscriber information and allows the phone to connect to a carrier's service.
Swapping a SIM card lets you transfer your phone number to a different device: I put my SIM card in a cheap phone while traveling abroad.
