unfortunately I currently have no time to try it on myself, but you can add Intents you want to receive on impotant points in the lifetime of the sms, like when sending failed or succeded. I don't know if this is already fully implemented by Google.
Using java Syntax Highlighting
void sendTextMessage(String destination, String source, String text, Intent sentIntent, Intent deliveryIntent, Intent failedIntent)
- Send a text based SMS.
