If your simulation is not responding or behaving erratically, check for these common pitfalls:
C:\ProgramData\Labcenter Electronics\Proteus 8 Professional\LIBRARY (Note: ProgramData is a hidden folder). Step 3: Restart Proteus
With no official library available, the best approach is to use the tools Proteus does provide to work with the serial communication of the SIM800L. Here are the most effective methods:
After successful installation, adding the SIM800L to your schematic is straightforward. sim800l proteus library
C:\Program Files\Labcenter Electronics\Proteus 7 Professional\LIBRARY 3. Initialize the Module in Proteus
Here are solutions to typical problems you may encounter:
Place a "Virtual Terminal" from the Instruments menu. If your simulation is not responding or behaving
Connect the pin of the SIM800L to the RXD pin of the Virtual Terminal.
What (Arduino, PIC, etc.) are you planning to connect to the SIM800L?
The SIM800L Proteus library is not the only way to simulate GSM communication. Several alternatives exist, each with its own advantages. What (Arduino, PIC, etc
Most of these are simply renamed SIM900 libraries. The pinout differs (SIM800L is usually 6 pins vs SIM900’s 40 pins). If you force this library, you will likely get "Logic contention" errors because the internal model expects a power supply pin that doesn't exist on the LGA-12 package.

Connect the VCC pin of the SIM800L to a DC power source component. Set the voltage between 3.7V and 4.2V. Connect the GND pin to the system ground.
