What is Wi-Fi Calling?

Wi-Fi Calling allows you to make and receive phone calls over a home Wi-Fi connection. Your compatible Telstra mobile will use a Wi-Fi network to connect with other compatible devices within Australia, giving you another way to make and receive calls when our 3G layer closes during 2024.  

Wi-Fi Calling is useful when:

  • You’re travelling overseas
  • You want to extend your coverage while indoors
  • You need to stay connected if there’s a mobile network outage.

There’s no additional charge to use Wi-Fi Calling on a Telstra mobile, and the Wi-Fi data is unmetered if you’re using a Telstra fixed broadband connection.

To use Wi-Fi Calling, you’ll need a 4G mobile phone which is Wi-Fi Calling capable.

Using Wi-Fi Calling

An icon will appear at the top of your phone, it looks like a phone with a Wi-Fi symbol next to it.

When this icon is present your phone will use Wi-Fi Calling if you make or receive a call.

What is Wi-Fi SMS?

Wi-Fi SMS lets you send and receive SMS on compatible devices when you’re connected to a supported Wi-Fi network. It’s ideal when you’ve got a Wi-Fi connection, but can’t connect to the mobile network to send or receive SMS messages.

If you’re already using Wi-Fi Calling, you just need to make sure your device is also compatible with Wi-Fi SMS and has the latest software version installed. There’s no need to change any other settings on your device.

Telstra Wi-Fi SMS means you can send and receive SMS messages while your smartphone is connected to Wi-Fi, but not able to connect to our mobile network. This may make it possible for you to send and receive SMS messages in places where it was previously not possible.
