I want to send a text message to my number using sim800l connected to Arduino nano 33 iot. My question is: should I write code for the sim card? Also, how could I define the sim card in the Arduino IDE. I need help, please
You might have better luck in the arduino forums or one more for the board/library you are using. We can answer things more about the network and configuration of the SIM but in terms of how to code up your project those alternatives might be a better starting place.
