If you just want to test your code logic (e.g., "Does my UART print work?"), use this minimalist approach:

Better yet: Use a DS1307 (RTC) or a Button as a stand-in. Replace if(sim800l.available()) with if(button_pressed) to test your SMS sending logic flow. sim800l proteus library

The SIM800L is a widely used low-cost GSM/GPRS module offering SMS, voice, and TCP/IP over GPRS via standard AT commands on a UART interface. Hardware testing requires SIM cards, antennas, and power supplies capable of handling high current spikes, which complicates rapid prototyping and education. Proteus, a popular electronics simulation environment, lacks an official, fully featured SIM800L model. This work presents a Proteus library component that models the SIM800L’s functional behavior for firmware development and teaching.

The holy grail is simulating GPRS data transmission (HTTP POST/GET). Few libraries support this, but some advanced paid libraries (e.g., from Labcenter’s VSM Studio partners) do. These sites provide step-by-step downloads with tested files

If you have such a library, you can simulate:

Without a high-fidelity library, your best bet is to create a Virtual Terminal script that mimics SIM800L responses. You can write a Python script that reads from Proteus’s COM port and replies with pre-defined responses. Hello from Proteus SIM800L +CMGS: 45 OK
