If you've got a Samsung Galaxy S7 or S7 Edge on the network without equal, you're in for a treat: Telstra has finally switched on Wi-Fi calling to offload your network activity onto a fast wireless connection. It's being rolled out as part of the Android 7.0 Nougat update being pushed to Aussie Telstra customers from today.
It's pretty simple: in the latest update, whenever you're on Wi-Fi, your calls will be delivered over that data network — in the same way as VoLTE sends your voice through 4G rather than the now-pretty-old-school 3G voice network.
It's a massive boon for anyone that lives in an area with terrible Telstra mobile coverage. Emergency calls still work as normal, and calls only require a measly 120Kbps of your connection's download and upload potential. The update should begin rolling out to Telstra-purchased Galaxy S7 and S7 Edge phones today.
