IoT SIM Card FAQs

How do IoT SIM Cards differ from traditional consumer SIM Cards?

IoT SIM cards differ mainly in usage scenarios and functionality. Traditional consumer SIM cards are typically used in personal phones, supporting voice, SMS, and data. In contrast, IoT SIM cards are designed for IoT devices, focusing on data transmission, low power consumption, and long lifespan. They generally offer higher security, wider coverage, and support remote management and updates, accommodating network requirements across multiple countries and regions.

What sizes are IoT SIM cards available in?

SIM cards come in 3 standard sizes: 2FF, 3FF, and 4FF. Some SIM cards offer all three sizes on a single card, known as triple-cut, while others may have just one specific size.
2FF (Mini) – 25 mm x 15 mm – Original industry standard for all SIM card form factors, used in larger wireless devices.
3FF (Micro) – 15 mm x 12 mm – About half the size of a mini-SIM card, commonly used in mobile devices.
4FF (Nano) – 12.3 mm x 8.8 mm – A newer, smaller form factor designed to save space in small wireless devices.
