hello.
To set up the 4G board, please follow these steps:

Hardware:

  1. Connect the 9V adapter to power on the GSM module.
  2. Insert a SIM card into the slot located on the backside of the board.
  3. If you’re in a remote area or experiencing signal issues, please attach the antenna.

Software:

  1. Update the phone number in the code to whom you want to send messages
    #define SMS_TARGET1 “98########”
  2. Set the APN (Access Point Name) based on your SIM card
    const char apn = “airtelgprs.com”; // Replace with your SIM’s APN
  3. Adjust the URL key in the code. Example using Pipedream
    String send_data_to_url = “https://eogas6eaag50nu2.m.pipedream.net”;

Notes:

  1. Use the universal Type-C connector and +9V 2A adapter for uploading code to the board.
  2. Monitor the LED indicator; a blinking of green LED confirms SIM connectivity.
