Remember the other day when we said EE's seamless WiFi calling feature was launching on April 10th? Well, there's been a slight change of plan, as the service is available right now on compatible iPhones (the 5s, 5c, 6 and 6 Plus). WiFi calling was originally supposed to launch alongside the Galaxy S6 and S6 edge in a couple of days, and we had no concrete details of when Apple devices might be joining the fray. That's changed today with the release of iOS 8.3, however, which adds support for EE's WiFi calling feature, among other things.
