MFF2 (M2M Form Factor)
Specialised SIM Card Form Factor for IoT Applications
The M2M Form Factor (MFF2) is a special chip-based form factor for embedded SIM cards, primarily used in the Internet of Things (IoT) and machine-to-machine (M2M) applications. These SIM are soldered directly onto the device's circuit board, offering enhanced durability and resistance to environmental factors, making them ideal for industrial and automotive applications.
