## Example Output
The example will get module and operator's information after start up, and then go into PPP mode to start mqtt client operations. This example will also send a short message to someone's phone if you have enabled this feature in menuconfig.
The example will get module and operator's information after start up, and then go into PPP mode to start mqtt client operations. This example will also send a short message to someone's phone if you have enabled this feature in menuconfig. The PPP connection will get restarted after 60 seconds.
