How-to enable Wi-Fi Calling on your iPhone

How-to enable Wi-Fi Calling on your iPhone

Matt Blowes September 08, 2017 Technology, How To

Wi-Fi Calling is a new feature to improve call quality and reception in areas with unreliable coverage. It makes use of Wi-Fi networks to allow calls to be placed over the internet, rather than mobile phone networks. 

For users suffering poor reception inside buildings, Wi-Fi Calling might be a viable solution. 

Despite using the internet to place calls, Wi-Fi Calling is billed at your phone provider's normal rate. Though this may not be an issue with so many unlimited calling plans. 

How to enable Wi-Fi Calling in iOS
  1. Open the Settings app > open Mobile.
  2. Open Wi-Fi Calling > Switch to On > A pop-up will appear, click Enable. Wi-Fi Calling will now be active.

Wi-Fi Calling is switched on when it displays in the signal section along the top of the iPhone. It will appear between the network name and the Wi-Fi signal strength indicator, seen here:

Do not be alarmed if you have enabled the feature, are connected to a wireless network and yet it does not appear. Wi-Fi Calling will only kick-in if the mobile network strength weakens compared to the local wireless network. 

Wi-Fi Calling is confirmed as a feature on the iPhone 5c or newer, on the following Australian mobile networks:

  • Telstra
  • Boost Mobile
  • Optus
  • Vodafone

Note: Wi-Fi Calling will not work on all Wi-Fi networks. Business-grade networks may need to be configured to allow the feature. 

Once enabled, calls can also be forwarded to other iOS and macOS devices within the same location. To switch-on forwarding to other Apple ID-linked devices, see Apple's guide here

For further details on enabling Wi-Fi Calling, including for Samsung Galaxy devices, see the how-to pages provided by TelstraOptus & Vodafone
