IoT SIM cards are used in IoT devices to identify them as they connect to cellular networks, providing global access to multiple carriers without requiring different cards for each country or region. These SIM cards come in various sizes and form factors, including traditional SIMs, mini SIMs, micro SIMs, nano SIMs, and embedded SIMs, which are directly mounted onto the circuit board of IoT devices. IoT SIM cards offer multi-network access to multiple carriers without requiring different cards for each country or region, providing choice and control for IoT solution companies. Examples of IoT devices include solar panels, wind turbines, medical equipment, retail POS devices, manufacturing materials, government sensors, real estate locks, transportation trucks, and agricultural tractors, among others. IoT SIM cards are used in various industries, such as Utilities and Energy, Healthcare, Retail, Manufacturing, Real Estate, Transportation & Logistics, Government / Public Sector / Smart Cities, Insurance and Banking, Agriculture / Smart Farming, or Automotive.
