For customers in rural and regional areas, who have dramas with mobile coverage, Wi-Fi calling is a game changer. It’s a basic idea that lets you make phone calls using your home internet instead of your mobile network.

To enable Wi-Fi calling on your device, there are a few steps that need to be taken into consideration:

  • Your device needs to be compatible with Wi-Fi calling. Most modern smartphones and tablets support this feature, but it’s always best to check to ensure compatibility.
  • A good router can ensure a stable and fast Wi-Fi connection, which is crucial for high-quality voice calls. If the router is old or faulty, it can cause dropped calls, poor call quality, or even prevent Wi-Fi calling from working altogether.
