| Feature | Simulation (Library) | Real Hardware | | :--- | :--- | :--- | | | Instant, always registered. | Takes 5-30 seconds. Depends on antenna/signal. | | Power Supply | Ignores voltage regulator needs. | Requires stable 3.8V @ up to 2A peak. | | Antenna | Not required. | Mandatory. No antenna = no network. | | SIM Card | Simulated via property. | Requires physical SIM with active balance. | | Timing Delays | Sub-second responses. | Real-world GSM responses take 0.5-3 seconds. | | GPRS HTTP/HTTPS | Rarely supported. | Fully supported (AT+HTTPACTION). | | | Power Supply | Ignores voltage regulator needs

This article serves as a complete resource. We will cover what this library is, how to download and install it, how to simulate sending an SMS, common errors (like "Invalid SIM State"), and the limitations of simulation versus real hardware. By default, Proteus does not include a native GSM module in its component library. If you search for "SIM800L" in the standard Proteus PICK DEVICE window, you will find nothing. This creates a barrier for students and hobbyists who want to design and test GSM-based systems without hardware.

// Set SMS to text mode sim800.println("AT+CMGF=1"); delay(1000);

Serial.println("Starting SIM800L Simulation..."); delay(2000);
