    This article is in need of a technical review.

    This feature is not on a current W3C standards track, but it is supported on the Firefox OS platform. Although implementations may change in the future and it is not supported widely across browsers, it is suitable for use in code dedicated to Firefox OS apps.

    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 perspective.


    var delivery = instanceOfMozSmsMessage.deliveryStatus;


    A string 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
    received success
    error error


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