MDN’s new design is in Beta! A sneak peek:


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


The selectNetworkAutomatically method is used to tell the radio to automatically select a network.

Note: If the network is actually changed by this request, the voicechange and datachange events are fired.


var request = navigator.mozMobileConnection.selectNetworks();


A DOMRequest object to handle the success or failure of the method call.

If the request fails, the request's error is one of:

  • RadioNotAvailable
  • RequestNotSupported
  • IllegalSIMorME
  • GenericFailure


var switchNetwork = navigator.mozMobileConnection.selectNetworkAutomatically();

switchNetwork.onsuccess = function () {
  console.log('Successful switch');

switchNetwork.onerror = function () {
  console.log('Unable to switch: ' +;


Not part of any specification.
