Android Question How to check for send SMS operation status / errors / result ?

I am doing a simple application to send short text messages (160 chars max).

I all works OK so far, but I want to check the status of the sending procedure, to see if the message has been sent and no error occured.

Is there a way to check the status , such as "SENDING", "MESSAGE SENT", "INSUFFICIENT CREDIT" ," NO SIGNAL" , "NETWORK PROBLEM" ... you get my point.

Thank you.
