In short you must have the simulation models of the components in order to imitate their actual behavior.

If you have the component in your circuit whose simulation model is not present in the library of your software then the software will be unable to simulate the behavior of the circuit.While simulating any circuit it is important to keep in mind that the simulation models of all the components that are being used in your circuit or embedded system must be present in the library of the software.There are a lot of the software and online tools available for simulating the circuit or embedded systems, among them Proteus holds the significant position which is equally popular among students and professionals. The simulation software calculates the behavior of the circuit by calculating the mathematical equation of all the components.Let us now summarize all the custom made simulation models required for simulating the embedded system designed based on the Arduino microcontrollerdevelopment board.The process for GSM module simulation is shown in the following steps.In this projectiot123 tutorial we will Learn the Download Proteus Library of Components.The simulation model of an electronic component contains the information about the input and output relationship of the electronic component in the form of the mathematical equation. The whole process indicating about how to place the simulation model in the library of the Proteus is discussed in my post on Ultrasonic sensor. You need to download the files containing the simulation models of the GSM and place it in the library of the Proteus. But unfortunately the simulation model of the GSM is not present on the library of the Proteus by default. So in order to simulate the GSM based system in Proteus the simulation model of the GSM should be present in the library of the Proteus. Without the simulation model your simulation tools whatever it is will not be able to imitate the behavior of the circuit. It is important to note here that if you want to simulate the behavior of any system you should have the simulation model of the all the components that are to employed within that system. The simulation prior to developing hardware saves both money and time. But before implementing the hardware and code in the real world it is always beneficial that you simulate the whole setup. Arduino microcontroller is very popular among students and hobbyists. The microcontroller commonly used for Prototyping along with the GSM module is Arduino.

As noted earlier in the post that the GSM module can be used in a variety of embedded systems such as GSM based home automation systems. After having the brief introduction on GSM and GSM module let us now looks at the simulation of the GSM in Proteus.
