The GSM network provides a reliable and secure platform for communication, which makes it a preferred choice for many applications.
The SIM card provides the module with a unique identification number, which is used to identify the device on the network.
The GSM module then communicates with the network using a set of protocols, which allows it to send and receive data.
It is responsible for establishing and maintaining the communication link between the device and the network.
The module also handles the encryption and decryption of data, which ensures the security of the communication.
