SIM card

The SIM card (Subscriber Identity Module) is the secure chip inserted in mobile terminals (mobile phones including smartphones, tablets, etc.) to access the mobile network. It stores information about the customer and thus makes it possible to personally identify the user and to record all information about the operator's network to which the user subscribes. It unlocks with a PIN code.
