EE is aiming to help those with poor mobile reception by rerouting the signal through a Wi-Fi connection
But the new service currently only works with certain high-end smartphones.

Fresh from handing out a free phone charger, EE is trying to rescue customers from losing their phone calls mid-chat.
The phone network's latest feature is designed to help customers living in mobile signal dead zones by running calls through a wi-fi signal to boost the strength.
Other networks (Three and O2) offer a similar service through apps, but EE says its service will be able to automatically switch between 3G, 4G and wi-fi to provide the best call quality.
At the moment, the service will only be available on the Samsung Galaxy S6, Samsung Galaxy S6 Edge and Microsoft Lumia 640 - which means if you use an Apple iPhone you're out of luck.
But the company says it will be adding more devices in the coming weeks and will have the feature available to five million EE pay monthly customers by the summer.
“Losing coverage at home is a major frustration, and wi-fi calling will make a real difference to millions of customers across the UK, from basement flats in London to the most rural homes in the country," said EE CEO Olaf Swantee.
The wi-fi calling option uses the phones normal dialler and normal contacts book - there's no need to download or install any extra applications.
Wi-Fi calling is only available on some phones because it requires specific hardware to be built into the handsets
"We have worked more than a year to make sure that everything works like a normal phone connection," Swantee told media.
Of course, the danger of the service is that if you happen to wander outside of your Wi-Fi range you'll lose the boosted signal.
The service doesn't just support phone calls. You can send and receive text messages through the wi-fi service in the same way as you would with message apps like WhatsApp and Viber.
Additionally, EE says customers won't see any additional charges appearing on bills as a result of using the new feature.
"Calls and texts come out of your monthly allowance as normal, and out of allowance calls will be charged at your standard rate," the company said.
