This API is available on Firefox OS for internal applications only.


The deliveryStatus property represents the current state of the message delivery from the recipient's perspective.


var delivery = instanceOfMozMmsMessage.deliveryStatus;


An Array of strings (one for each recipient) which can be one of the following:

  • pending        : The message is awaiting delivery.
  • success        : The message has been sent by the device.
  • error          : The message could not be delivered.
  • not-applicable : The message has been sent without status report requisition.

The values of that property are conditioned by the value of the property:

delivery deliveryStatus
sending pending
sent pending
The following is pointless as deliveryStatus has no real meaning when receiving a message
not-download success
received success
error error


This is a non-standard implementation, but it is discussed at W3C as part of the System Application Working Group.
