SIM CARDS AND MOBILE CONNECTIVITY
A Subscriber Identity Module (SIM) card is a small, portable card used in mobile devices to securely store and transfer subscriber data, such as phone numbers, contacts, and network-specific information.
An IMSI (International Mobile Subscriber Identity) is a unique identification number assigned to a SIM card in a mobile network. It helps identify and authenticate the subscriber on the network.
It is the unique numerical identifier assigned to an IMSI. It consists of three components: Mobile Country Code (MCC), Mobile Network Code (MNC), and Mobile Station Identification Number (MSIN). The IMSI number is used to identify and authenticate the user in the mobile network.
It is a SIM card that is integrated into a device, such as a smartphone, tablet, or IoT device, during the manufacturing process. It enables the device to connect to a mobile network without requiring a physical SIM card to be inserted or replaced.
It refers to the capability of a device or network to support multiple SIM cards simultaneously. This enables the device to connect to different mobile networks or have multiple mobile numbers on a single device.
IOT AND CONNECTIVITY TECHNOLOGIES
"IoT" stands for the "Internet of Things." It's a network of smart, connected objects like devices and machines that can collect and share data with each other via the internet. These objects can work together and perform tasks without human involvement. IoT makes things smarter and more efficient in areas like healthcare, transportation, and more.
An IoT device is a smart, internet-connected object or gadget that can collect and exchange data with other devices and systems.
IoT device management refers to the process of monitoring, controlling, and maintaining a fleet of IoT devices throughout their lifecycle. It involves tasks like provisioning, firmware updates, security management, and remote troubleshooting.
LTE-M, also known as Long-Term Evolution for Machines, is a low-power, wide-area network technology designed for IoT devices. It provides improved coverage, longer battery life, and better network penetration for IoT applications compared to traditional cellular networks.
NB-IoT (Narrowband Internet of Things) is a low-power, wide-area networking technology designed for connecting IoT devices. It provides efficient and reliable communication over long distances while consuming minimal power. NB-IoT is suitable for applications that require low data rates, long battery life, and deep indoor penetration.
