MozMobileConnectionInfo.roaming Redirect 1

This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

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


roaming is a read-only property that indicates whether the connection is going through a foreign operator (true) or not (false).


var dataRoaming  = navigator.mozMobileConnection.data.roaming;
var voiceRoaming = navigator.mozMobileConnection.voice.roaming;


Return a boolean.


Not part of any specification.
