A typical SIM card (mini-SIM with micro-SIM cutout) T-Mobile nano-SIM card with NFC capabilities in the SIM tray of an iPhone 6s cell phone A SIM (Subscriber Identity Module) card is an integrated circuit (IC) intended to securely store an international mobile subscriber identity (IMSI) number and its related key, which are used to identify and authenticate subscribers on mobile telephone ...
An eSIM (embedded SIM) is a form of SIM card that is embedded directly into a device. Instead of an integrated circuit located on a removable SIM card, typically made of PVC, an eSIM consists of software installed onto a eUICC chip permanently attached to a device. If the eSIM is eUICC-compatible, it can be re-programmed with new SIM information.
The pinouts are the dark circles surrounding the integrated circuit. An integrated circuit (IC), also known as a microchip, computer chip, or simply chip, is a small electronic device made up of multiple interconnected electronic components such as transistors, resistors, and capacitors. These components are etched onto a small piece of ...
A smart card (SC), chip card, or integrated circuit card (ICC or IC card), is a card used to control access to a resource. It is typically a plastic credit card-sized card with an embedded integrated circuit (IC) chip.
