Sends SMS from through connected USB GSM modem (Mac OS)

I'm looking for a basic program which sends and receives SMS messages via USB GSM modem connected to a mac.

The program will run in the background and require no user interface (other than initial/setup configuration).

The program should subscribe to a Azure message queue and when messages are placed in the queue, immediately send them.

The program should support configuring "hours of operation" - if messages are places in the queue at midnight or 1AM, they will not be delivered until 8AM (configurable)

When the SMS messages are received to the USB modem, the program will post the response to a URL containing the details of the message.

The program needs to heal itself if power is lost (basically start when the computer comes back online)

The program needs to handle error from the USB correctly (send an email when SMS cannot be sent due to low balance or other issues (bad signal, etc.)

Xamarin/C# not a requirement but a plus.

Taidot: Azure, C# -ohjelmointi, Linux, Mac OS, Xamarin
