Compare the different SIM format described in the specifications: Full-size vs Mini-SIM vs Micro-SIM vs Nano-SIM vs Embedded-SIM. Thanks to Apple and it's iPhone versions, there is now several SIM sizes used in our smartphones or tablets.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 .
There are mainly 6 types of SIM cards: Full-Size SIM Cards (1FF), Mini SIM Cards (2FF), Micro SIM Cards (3FF), Nano SIM Cards (4FF), eSIM (Embedded SIM), and Integrated SIM. There are four main SIM form factors: Standard SIM (1FF), Mini-SIM (2FF), Micro-SIM (3FF), Nano-SIM (4FF), and embedded MFF2 SIM. Each form factor differs in size and thickness, but the chip itself remains the same across form factors 2FF–4FF. Here's a quick reference table summarizing the benefits and differences of each SIM form factor:
SIM card sizes and types. Different form factors (FF) co-exist: The credit-card-sized SIM is now obsolete; A regular SIM or 2FF measures 15 millimeters by 25 mm ; A smaller version of the SIM called the micro-SIM, or 3FF SIM card (Third Form Factor), is 12mm by 15mm; The nano-SIM or 4FF is 8.8 mm by 12.3 mm Mini SIM (2FF) At 25mm x 15mm x 0.71mm, the Mini SIM is the largest removable SIM card currently in use. It’s been around since the mid-1990s, when it emerged as a smaller option (at the time) for shrinking mobile devices. Today, the Mini SIM still works well for larger connected devices, like cars and vending machines. Micro SIM (3FF)

Today's standard SIM is the second SIM form factor (2FF). Also known as a Mini-SIM, measuring around 25mm long by 15mm wide it is the largest available SIM form factor. It is typically used for large IoT/M2M devices, such as vehicles. What is a 3FF Micro SIM?
The five SIM form factors are 1FF (the largest), 2FF, 3FF, 4FF and MFF2 (the smallest). Discover more about the differences between these form factors, and their suitability for various use cases. In all the 1FF – 4FF formats, the SIM chip is incorporated into a dedicated card, which is inserted and removed from the device via a tray mechanism. Understanding the various SIM card types is crucial for selecting the right one to ensure seamless connectivity and optimal performance. Mini-SIM (2FF): The Mini-SIM, also known as the "full-size" SIM, was the standard SIM card size for many years. 2FF SIM card (Mini SIM card): 12 times smaller than standard SIM, SIM cards launched in 1996. 3FF SIM card (Micro SIM card): built-in 2003, 1cm smaller in length and 0.2cm smaller in width for compact mobile devices. 4FF SIM card (Nano SIM card): introduced in 2012, the smallest physical SIM.
