What is VoWIFI or WIFI calling?
VoWIFI enables voice calls (incoming and outgoing), MMS** and SMS** over a WiFi network. VoWIFI is available if you have a compatible plan, a compatible device, you are connected to a supported^ WiFi network and your mobile network coverage is poor or non-existent.

* For Telstra customers, VoWIFI traffic (data) is not charged to your Telstra internet account.
** Not available over the Telstra network (July 2017). Telstra advises that text services will be implemented.
^ Almost any home or business WIFI network will support VoWIFI. It is important that the WIFI signal is strong, so keep the phone relatively close to your WIFI router. The quality of your internet connection must be sufficient to support VoWIFI calls.

There are four key pre-requisites for VoWIFI.
1. Your phone must support VoLTE or Voice over LTE. This technology enables voice calls over 4G networks. Until recently voice calls were carried over the 3G network and prior to that over the 2G network. VoLTE delivers some great improvements to voice calling. You can experience faster call connection times compared to 3G and you may talk and browse at the same time. VoLTE voice calls are high definition (HD) for sharp, clear call quality. See the carrier links below for details on enabling the VoLTE feature.
2. With the exception of approved Apple smart phones, your approved mobile phone must be supplied by Optus for the Optus WIFI calling service and Telstra for the Telstra VoWIFI service. See the Carrier links below for details on enabling the VoWIFI feature.
3. Mobile Phones supporting VoWIFI are currently limited, but slowly expanding (see details of approved phones below).
4. You must ensure that the latest software is loaded on your mobile phone.
What is the Cost? There are no additional mobile network charges for WiFi Calling. Your calls and messages will be charged as per the rates of your existing mobile plan.
VoWIFI (WIFI calling) voice calls use approximately 3.8MB of internet data for a 5 minute call.
