 For outgoing TextMessages, ofono updates the history plugin in two method calls, first all the text message history related properties msg id, message , local received time,actual sent time, lineid and status='Pending' and in another method ofono updates plugin with the status. Earlier design, I sent out history record with pending status and  when I received  status update I  used  'property changed'  signal for status update. But I use 'uint32,variant' type which is not consistent with the current ofono property changed signal type. My questions,
 1) Are you ok with using signal for status update, this lets us send out history as soon as we receive them if the agent is running      

 2) If we want to avoid signal, then we can store the outgoing text message record until we receive the status update from ofono, combine them and send out in case of agent running. In case of agent not running we do this anyway.
