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

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


The selectNetwork method is used to manually select a network, overriding the radio's current selection.

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


var request = navigator.mozMobileConnection.selectNetworks(network);


A MozMobileNetworkInfo object representing the nework to select.


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 connection = navigator.mozMobileConnection;
var availableNetwork = connection.getNetworks();

availableNetwork.onsuccess = function () {
  var network = this.result[0];

  var switchNetwork = connection.selectNetwork(network);

  switchNetwork.onsuccess = function () {
    console.log('Successful switch to: ' + network.longName);

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

availableNetwork.onerror = function () {
  console.log('No network available: ' +;


Not part of any specification.
