I am unable to establish a network connection with the 4G module.

4G module depends on the following setup for connecting to mobile network. Please ensure these are in place:

  1. 9V 2A DC power adapter to be connected to the DC jack provided on the board.
  2. Nano Sim card to be inserted properly into the slot and ensure it has currency to send SMS/Https request.
  3. Connect 4G antenna to the SMA connector on the board.
  4. Download 4G sample program from GitHub https://github.com/edgehax/4G-LTE-MODULE-SIMCOM-A7672S-ESP32 and upload using Arduino IDE.
  5. Observer the serial monitor on the Arduino IDE and check the log messages for 4G operations.
