GSM Test Web Server

This sketch creates a web server to accept incoming connections on the Arduino MKR GSM 1400. Some network providers only allow requests from inside their own network. You will need to check with your network provider to make sure your SIM card will accept incoming HTTP requests.

/*
  Basic Web Server

 A simple web server that replies with nothing, but prints the client's request
 and the server IP address.
