When will my device be supported?
We’re working closely with our device vendors to support the technology and will be updating our list of compatible devices as they become available.
What if I use different a DNS (Domain Name Service) on my Wi-Fi modem?
Telstra supports the ability to use any DNS, however in some instances it can impact the location reported to the network, affecting location aware services such as regional dialing (where an 03 or 02 is automatically added to a local number) and 1800 / 1300 services. We recommend using Telstra DNS for best results.
Can I use Wi-Fi Calling on a VPN?
No, VPNs are not supported.
Why does my Wi-Fi Calling connect on my home network, but not on my friends Wi-Fi network?
There are a few reasons Wi-Fi calling may not be working, such as the Internet Service Providers (ISP) being incompatible, specific firewall settings and other configuration issues with business and public Wi-Fi hotspots.
How will I know when I have Telstra Wi-Fi Calling?
You can check telstra.com/wificalling to see whether your device is compatible, we’ll be updating our list of eligible devices as the functionality becomes available. When customers are on a Telstra Wi-Fi Call their handset will continue to display a Wi-Fi call icon next to the signal bar. Some devices may show variants of this icon based on the manufacturer.
I can’t see the Wi-Fi calling icon at the top of my phone screen
An icon will appear at the top of the mobile screen, next to the existing Wi-Fi signal icon, if you cannot see this icon and you see the message ‘Fail to connect to VoWiFi’ then Wi-Fi Calling is not possible in your current location.
I saw a ‘Fail to connect to VoWiFi’ message, what is this?
This message means that the Wi-Fi Calling was not able to connect via your current Wi-Fi hotspot. The reasons for this can include:
• Using a Wi-Fi hotspot on an unsupported Internet Service Provider
• Using a Wi-Fi hotspot that has a firewall that blocks the Wi-Fi Calling
• Using a Wi-Fi hotspot outside of Australia. Wi-Fi calling is currently only available within Australia.
What happens to calls when I enter or leave Wi-Fi coverage?
If you’re entering or leaving 4G coverage, the call will seamlessly transition between Wi-Fi and 4G. If you’re entering or leaving 3G coverage, then calls will drop when moving to and from Wi-Fi.
Why can’t I use Wi-Fi Calling for all my calls?
Wi-Fi Calling helps you make and receive calls over Wi-Fi, where previously you couldn’t make calls due to issues with coverage. Where there is 3G or 4G coverage, your phone will always make the call over the mobile network. Only when the 3G/4G coverage is insufficient to make a call will the phone switch to Wi-Fi Calling (if available).
Where can I make my Telstra Wi-Fi Calls from?
If you're within range of a supported Fixed Broadband Wi-Fi connection and there is no Telstra Mobile coverage available, your mobile will automatically use Wi-Fi to make calls. It will choose the best connection type (4G, 3G, Wi-Fi) available and automatically connect.
Is there any change to the way I make or receive calls on my phone using Telstra Wi-Fi Calling?
No, you make and receive calls as normal. Furthermore, your MessageBank and EasyCall features (such as Call Waiting and Call Conference) and #100# will still work as per normal.
Why can’t I change my Call Forwarding settings when using Wi-Fi Calling?
Currently calls will be forwarded based on your existing settings whilst you are in Wi-Fi Calling mode, you won’t be able to change the forwarding settings until you are connected to the Telstra Mobile Network.
Will my home Wi-Fi modem/router work with Wi-Fi Calling?
If you are using a Telstra Gateway or modem that is less than 4 years old it will be compatible with Wi-Fi Calling. If your modem is from another Internet Service Provider (ISP), you’ve purchased yourself or over 4 years old from Telstra, the modem/router may be compatible. For your modem to support Wi-Fi Calling it will need to have:
1. IPSec pass-through feature (enabled) and;
2. Certificate Fragmentation support.
What broadband bandwidth is needed for Wi-Fi Calling to work properly?
Wi-Fi calling uses around 100 – 120kbps. The majority of broadband services should be capable of running Wi-Fi calls. Delays can be an issue for Wi-Fi calls, so in situations where there is high latency on broadband (i.e. Satellite) then call quality may be reduced.
What happens if lots of people are using the internet at the same time and I make a Wi-Fi call?
Telstra Wi-Fi Calling uses only a small percentage of what might be considered a slow broadband service. However high downloads (e.g. streaming video) may possibly result in a loss of voice quality in extreme circumstances. If you have poor upload speeds your Wi-Fi Call may disconnect.
Can I choose Wi-Fi Calling as my preferred calling option?
No, your mobile will automatically choose the best available connection type (4G, 3G, Wi-Fi) and automatically route calls through that connection. However, on Samsung devices capable of WiFi calling, you can enable Airplane Mode on your device and turn on Wi-Fi. A Wi-Fi call will then be able to be made. (Please note that this override approach is not available on other devices including iPhones)
I think Telstra Wi-Fi Calling is causing problems with my call experience
We thoroughly test our range of devices to ensure the best performance on our Mobile Network. Wi-Fi calling is only enabled on devices that have passed our testing. We will be proactively monitoring the call performance of our Wi-Fi compatible devices to ensure they are working correctly. You can disable Wi-Fi Calling in your mobile settings (see details below).
What about International Roaming?
There are currently no Wi-Fi Calling roaming agreements. Your device will automatically fall back to 3G circuit-switched to make calls when overseas and standard international roaming rates apply. If you try to connect to a hotspot while overseas you’ll receive the error message ‘Fail to connect to VoWiFi’.
Will Telstra Wi-Fi Calling only work on compatible devices purchased from Telstra, or will Telstra Wi-Fi Calling also work on BYO devices purchased outright from third party retailers and then moved to the Telstra network?
iPhones: Compatible iPhones purchased from third party retailers will support Telstra Wi-Fi calling if the customers moves their service to the Telstra network as a BYO device. These customers will need to update their settings when connecting to the Telstra network in the normal way.
Samsung: In general compatible Samsung devices purchased from third parties moved to the Telstra network as a BYO device will not support the Telstra Wi-Fi Calling feature.
At this point the only exception to this is Galaxy S8 and S8+ open firmware devices purchased directly from Samsung
Setting up Telstra Wi-Fi Calling on Android

When I look at my bill, I see locations that don’t match where I called from
When you make a call, the phone will first try and connect to the mobile network. If that doesn’t work, it’ll then attempt a call over Wi-Fi. This means the normal way of locating a device (the mobile towers) can’t be used. There are ways of storing this information on the device for short periods. However, not all devices support this. Telstra will use the best information available to assist with locating your device, but in some cases it’s possible identified with a default regional location, such as VIC/TAS, NSW/ACT, QLD, SA/NT or WA.
Do location based services still work?
Yes, in the vast majority of cases calls made using Telstra Wi-Fi Calling will use your location. In some rare instances the network may lose track of the location and in which case the following may occur:
If you are connected to a Telstra Fixed Broadband service for the Wi-Fi connection then will be provided a regional location of NSW/ACT, VIC/TAS, QLD, SA/NT or this is the location that will be recorded against the call and will appear on your bill if you have a detailed bill.
If you’re using another ISPs broadband, then you’ll be provided a default location of NSW/ACT. In this situation if you attempt to dial a local number and aren’t in NSW/ACT, then you must use the area code (i.e. 03 9000 000), otherwise the call may be misdirected. The location ‘Unavailable’ will appear as the location on the bill if you have a detailed bill.
Will emergency calls still work?
When I make a call it tells me the number is incorrect, or that I’ve connected to the wrong number
(Also see ‘When I look at my detailed bill I see locations that don’t match’)
Telstra will use the best information available to assist with locating your device. However, in some cases it’s possible that you will be with a default regional location, such as VIC/TAS, NSW/ACT, QLD, SA/NT or WA. Each default region uses its own local calling codes (i.e. 03, 02, etc.), so if the contacts in your phone do not include an area code, the default region code will be added. If a call in VIC (03) is made whilst a default location of NSW (02) is recognised by the device, it’s possible for a wrong number, or invalid number to be dialled. This also affects 13, 1300 and 1800 numbers.
If this happens, one way of resolving the situation is to move back into a coverage area and turn the airline mode on and off, which should reset the location. For some devices with Qualcomm chipsets, it may be necessary to do this every 70 minutes whilst in Wi-Fi coverage. Alternatively, adding the correct area code to numbers in your phone book will also solve the problem.
