***Important Notes:***
***Power Supply: This module requires a stable voltage (5V-16V). Use an external power adapter capable of at least 2A. Using the ESP32's 5V pin is often insufficient and causes reboot loops.
***Library: Do not use the default TinyGSM library from the Arduino Library Manager. Use the modified version linked above.
