Hello friends, I hope you all are doing great. Today, I am going to share the LilyGO T-Call SIM800L Library for Proteus . The T-Call is a black ESP32 board with a SIM800L 2G modem on it, so one small board has Wi-Fi, Bluetooth and a SIM card. It can send an SMS or take a call from a field, a boat or a water tank, far from any router. With this library it runs your ESP32 Arduino sketch in Proteus 8.5, and the modem on the board answers real AT commands.
