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.
