Advantages and disadvantages of MSISDN

In a system where different devices interact, you need a way to identify and differentiate these devices. MSISDN is an effective and globally recognised way to achieve this.

However, the transferability of MSISDNs may become a risk. Therefore, the management of devices and SIMs is important, especially when there are a large number of devices. To avoid problems, it is advisable to manage this through an IoT portal and a dedicated service provider.
