Well today o2 released an update to the o2 app with a welcome addition of an Apple Watch app, but I do wonder why the tech guys don't release an update to enable wifi calling on iPhones? EE & Vodafone have enabled this feature, am I missing something? Is it because Tugo and Wifi calling cannot coexist? Whilst I like Tugo, I would prefer a native version built into the iPhone. Come on o2 let's have it! 🙂
