Good news for Three customers who live in mobile black-spots: The company has today announced that wifi calling is available on its network for the first time.
The technology, which has been available on EE and Vodafone for some time, uses a wifi hotspot to connect to your network instead - and enables you to receive calls and texts even when you're out of range of a traditional antenna.
According to Three's press release, it'll work across both iOS (v10.2 and above) and Android (with "the latest software update"), as long as you have a compatible device. At the moment, al of the iPhones from the iPhone 5S and 5C upwards support the technology - as does the Samsung S6 and S6 Edge. The S7 and S7 Edge will apparently support wifi calling from mid-February.
The even better news is that it means you can finally delete the Three InTouch app from your phone, which previously enabled wifi calls and texts, but wasn't directly integrated into your phone's operating system.
So now it appears that it is only O2 customers who are waiting - and who will have to use the annoying "TuGo" app in the meantime.
