How to enable call and SMS over Wi-Fi on Telstra

By Luke Hopewell July 23, 2021

If you’re outside of a mobile coverage area, there’s still a way for you to make and receive calls, and send SMS messages back and forth over your Wi-Fi network. Here’s how to do it.

What is Telstra SMS over Wi-Fi?

SMS over Wi-Fi allows you to send and receive SMS messages on via your fixed Wi-Fi network.

Instead of sending the SMS using mobile signal, modern smartphones use the connectivity found via the Fixed Wi-Fi network at your home or business to get the message out.

To be able to use Wi-Fi SMS, you need to:

  • Have a Telstra approved Wi-Fi SMS compatible device
  • Have VoLTE enabled on your device
  • Have updated to the latest device OS software
  • Turn on Wi-Fi calling on your device

It takes a few steps to enable, which you can find below.

How to enable Telstra SMS over Wi-Fi

First, you need a compatible device. You can check to see which devices are compatible on our regularly updated Support Centre.

For iPhone:

  1. Go to Settings
  2. Select Mobile
  3. Turn on Wi-Fi calling. This will also enable Wi-Fi SMS

To enable Wi-Fi SMS, you’ll also need to disable and re-enable iMessage if it’s already turned on:

  1. Go to Settings
  2. Select Messages
  3. Turn iMessage off
  4. Restart the phone
  5. Turn iMessage back on

For Android devices:

  1. Go to your phone’s calling app
  2. Select More or the three dots in the top right corner
  3. Select Settings
  4. Turn on Wi-Fi Calling. This will also enable Wi-Fi SMS

What is Wi-Fi Calling?

Wi-Fi calling enables you to make calls using a fixed broadband Wi-Fi connection from your compatible Telstra mobile when you can’t connect to the mobile network.

Your mobile simply uses your Wi-Fi network instead of the mobile network, so you can make and receive calls as you would normally.

Plus when roaming overseas and connected to Wi-Fi, Wi-Fi Calling allows you to make and receive calls back to Australia at no additional charge.

Calls to destinations other than Australia over Wi-Fi Calling when roaming overseas are not enabled and will need to be made over the mobile network. Standard charges apply.

To use Wi-Fi calling, you need to:

  • Have a Wi-Fi calling compatible smartphone or tablet. This includes:
    • Apple iPhone 6 onwards, Apple Watch 3 onwards
    • Samsung Galaxy devices, S7 onwards, Note 5 onwards
    • Google Pixel 2 devices onwards
    • LG devices G6 onwards
  • Have 4G voice calls enabled
  • Have up-to-date software
  • Turn on Wi-Fi calling

Switching on SMS over Wi-Fi on our mobile network

By Nikos Katinakis May 6, 2020

We’ve enabled a feature on our network to help you more easily receive SMS messages wherever you are.

SMS over Wi-Fi means that when your phone is connected to a Wi-Fi network that can access the internet, you’ll still be able to receive SMS messages even if your phone is not in an area where it can connect to our mobile network. We’ve supported Wi-Fi calling on many devices for several years, so you might already be familiar with using Wi-Fi to access your mobile services.

Updates to enable SMS over Wi-Fi on some mobile handsets have gone live overnight and will roll out progressively over the next week. Some of our customers will already see the functionality available on their devices. You can find an up-to-date list of supported devices at our SMS over Wi-Fi page.

To make sure you receive these updates as soon as they’re available for your device, you should make sure your phone is set up to receive automatic updates. If you need a hand, you can find out how to enable automatic updates from Apple and from Samsung.

Here’s how to turn on SMS over Wi-Fi with Telstra.
