If you own an iPhone with an EE plan, you can now Wi-Fi call a friend.

Two days after announcing its Wi-Fi Calling feature, which lets you place voice calls and send text messages via a Wi-Fi network, EE has made the new feature available for iPhone 6, iPhone 6 Plus, iPhone 5S, and iPhone 5C.

The service, which was suppose to go live on 10 April (alongside the launch of the Samsung Galaxy S6 and S6 edge), launched early due to the release of iOS 8.3. The update added support for EE's Wi-Fi Calling, among other things.

Enable Wi-Fi Calling

To begin using EE's Wi-Fi Calling feature from tonight, follow these steps:

  • Go to Settings, then General, and Software Update on your iPhone
  • Choose the Download and Install option
  • Go to Settings, Phone, and Wi-Fi Calls on your iPhone
  • Turn on the Allow Wi-Fi Calls setting

EE said it will see that you’ve allowed Wi-Fi Calls, and then it'll "provision your phone" within a day. Once you’ve received access to use the new feature, you can turn it off or on whenever you want under Phone in Settings.
