Ever wondered how your phone calls and texts always find the right person? It's all about a complex network with its own language. One key term you might encounter is MSISDN which stands for Mobile Station International Subscriber Directory Number. In other words, it's the unique identification number behind your regular phone number, the one you use for calls and texts.
So, what is a MSISDN? It stands for Mobile Station International Subscriber Directory Number. In simpler terms, it's the unique identifier assigned to your mobile phone number within a GSM (Global System for Mobile Communications) or UMTS (Universal Mobile Telecommunications System) network. It essentially acts as the bridge between your phone number and the SIM card (Subscriber Identity Module) inside your device.
While MSISDN is the number you use for calls and texts, it's important to distinguish it from another crucial identifier: the IMSI (International Mobile Subscriber Identity). The IMSI, embedded within the SIM card, serves as a more technical identifier for your mobile device and network.
The realm of mobile communication extends far beyond smartphones. In the ever-growing landscape of IoT, let’s discuss what is MSISDN’s new list applications. Many IoT devices, like connected cars or industrial sensors, require mobile connectivity to transmit data. An MSISDN can be assigned to these devices, enabling them to function within cellular networks. This allows for secure and reliable communication between these devices and their designated management systems.
Activation. During device activation, the mobile network operator assigns a unique MSISDN to the device's SIM card.
Connectivity. The device connects to the network using the cellular signal.
Identification. The network identifies the device based on the received MSISDN.
Data Transmission. The device transmits or receives data using the established connection.
Overall, what is the MSISDN number function? Being a unique identifier within the network, MSISDN facilitates seamless communication for a wider range of devices, not just phones, paving the way for a more interconnected future.
