The current semantics are that the DBusMessage returns only when the SMS has 
been successfully sent to the network, or oFono determined that it cannot send 
it.  So you can assume that SMS is pending as soon as dbus_message_send is 
performed by your client.  And that SMS has been sent/failed as soon as the 
message call returns.

The history plugin is given a bit more information.  It is notified when the 
SMS is queued, successfully sent / not.

This is what the history plugin is for.  History is notified when an SMS comes 
in and can persist this information however it wishes.  The plugin can even 
define its own D-Bus interface for notifying external clients if needed.

You don't have to use history plugin, but it can make certain tasks really 
easy.
