Today Three announced the rollout of free Wi-Fi calling features, allowing anyone with a compatible iOS or Android device to make phone calls with their phone, for free via the UK mobile network.
This also allows you to call and text even when you have a poor cellular signal, as long as you have an active Wi-Fi connection.
Here’s how to get it set up:
Set it up for iOS
To get started with Three’s new Wi-Fi calling features on iOS you will need to have an iPhone 5C, an iPhone 5S, an iPhone 6, an iPhone 6S, and iPhone SE, or an iPhone 7.
For some reason, the list doesn’t include the iPhone 6 Plus, the iPhone 6S Plus, or the iPhone 7 Plus.
If you have any of the compatible devices then you will also need to make sure that you have iOS 10.2 or above installed on your device.
If that is also fine, then you need to head over to the settings app on your iPhone, hit the phone button, and then switch on the WiFi calling feature. From then the feature will be active.
Set it up on Android
At the moment there are only a small number of Android devices that support WiFi calling with Three, only including the LG G5, Samsung Galaxy S6, and the Galaxy S6 Edge.
These devices will soon receive a software update, after you install that the feature will be enabled automatically.
Three does plan to roll out the feature to more devices soon, including the Samsung Galaxy S7 and the galaxy S7 Edge by the end of February 2017.
We will update you when we hear more about that.
