Set a Preferred Network to Cellular on an Android Airwall Agent

Most Android devices will not use Cellular if either Wifi or Ethernet is available. If you want to set your Preferred Network to Cellular, most devices require that you enable Mobile data always active in your device's Developer options.

To do this, on your Android device, you need to:
  1. Enable Android Developer Options.
  2. Enable Mobile data always active.
More details on how to do this are in the following sections.

Enable Developer Options

  1. On your Android device, go to Settings > About Phone .
  2. Tap Software Info > Build Number.
  3. Tap Build Number seven times. After the first few taps, you should see the steps counting down until you unlock the developer options. You may also have to tap in your PIN for verification. Once developer options are activated, you see a message: Developer mode is now turned on.
  4. Go back to the Settings page, where you will now find Developer options as a choice at the bottom.

To enable “Mobile data always active”

  1. Go to Settings > Developer Options.
  2. Enable Developer Mode, if needed.
  3. Under Networking, scroll to find Mobile data always active, and tap to enable it.
