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.

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.

IoT network cards can be used on smart hardware such as bird feeders, hunting cameras, locators, solar powered cameras, mobile power banks, MIFi, and any product or scenario that requires network connectivity in WiFi free environments.

I can't. Using IoT network cards on mobile phones is illegal. If you need to use them on your phone, please go to the local business hall to apply for a mobile card.
