EE springs Wi-Fi phone calls on not-spot sufferers, Tube riders

When there’s no signal in your neighbourhood, who ya gonna call? Er, anyone you like

EE today said it will be the first UK mobile network to roll out full-blooded next-generation Wi-Fi calling.

Subscribers will not need to install any special apps: their phones should be able to seamlessly and automatically send and receive text messages, and make and receive calls, via wireless networks when there is no cellular network signal. You’re out of luck if there’s no usable Wi-Fi to latch onto, obviously.

This new feature uses part of the LTE spec that’s been a very long time coming: IP-Multimedia Subsystem (IMS), which was defined more than a decade ago.

LTE mobile broadband is an all-IP network, meaning calls and texts can go over Wi-Fi if that’s available and VoLTE (Voice over LTE) is implemented. Otherwise, it will drop back to 3G for circuit-switched calls, which is useless if there’s no cellular signal.

(Three has a similar service, but needs an app installed. Vodafone is bringing out a rival later this year.)

EE told us it has been working on the Wi-Fi calling service for three years. It requires support from the handset makers and the operating system builders. Roughly speaking, 4G handhelds that went on sale from mid-2014 can take advantage of the service.
