Create a function that works only once after the application is installed on the phone

I am developing a mobile application using ApacheCordova / Phonegap. I need a function that sends me an SMS once per installation. If I put my function on "DeviceReady", it will run every time the application opens. Is there any solution for the function that will be launched when the application is installed or when it is executed for the first time?

Any suggestion would be appreciated.
