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


The getSegmentInfoForText method is used to get the information necessary to create a multi-part SMS for a given text.

Note: Starting with Firefox OS 1.2, this method has become asychronous and will return a DOMRequest object instead of a direct MozSmsSegmentInfo object.


var segments = navigator.mozMobileMessage.getSegmentInfoForText(text);


A string representing the text to send as a potential multi-part SMS.


Before Firefox OS 1.2: A MozSmsSegmentInfo object with all the necessary information about the text.

Since FIrefox OS 1.2: A DOMRequest object to handle the success or error of the operation. In case of success the request's result is a MozSmsSegmentInfo object with all the necessary information about the text.


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