An IoT SIM card is a specialized SIM card designed for use in Internet of Things (IoT) devices. Unlike traditional SIM cards, which are primarily used for voice calls and text messaging, IoT SIM cards are optimized for data transmission and machine-to-machine (M2M) communication. They typically have larger memory capacities and are more durable to withstand harsh environments.
An IoT SIM card contains a microchip that stores unique information about the device, such as its identity and credentials. This information allows the device to connect to a cellular network and transmit data. IoT SIM cards can be activated and managed remotely, making them ideal for large-scale deployments.
IoT SIM cards come in a variety of form factors, including:
No, not all IoT SIM cards are tied to a single carrier network. Some IoT SIM cards are global and can connect to the best available networks in any region. This is particularly useful for devices that need to operate in multiple countries or regions.
eUICC stands for embedded universal integrated circuit card. It is a technology that allows a SIM card to support multiple subscriber profiles over its lifetime. This means that an eUICC SIM card can switch between different cellular carriers without requiring physical replacement.
An eSIM is the physical hardware that supports eUICC. It is a type of SIM card that is embedded directly onto the device's circuit board. eSIMs are typically smaller and more durable than traditional SIM cards, making them well-suited for IoT applications.
