How to interface GSM module with 8051?

Initially, connect the circuit as shown in the circuit 8051 Microcontroller diagram. Switch on the power supply. Now send a message from any other phone to the SIM present in the GSM module. Whenever a message is received by the GSM, it is displayed on the LCD.

What is the need of interfacing in 8051 microcontroller?

Interfacing is one of the important concepts in microcontroller 8051 because the microcontroller is a CPU that can perform some operation on a data and gives the output. However to perform the operation we need an input device to enter the data and in turn output device displays the results of the operation.
