BT has launched a free smartphone application for Android and iPhone devices, allowing BT Total Broadband customers to automatically connect to BT's network of Wi-Fi hotspots.
The BT FON application is unlimited and free for users with a BTinternet e-mail username and password. There are 1.6 million Wi-Fi hotspots - made up of BT Openzone and BT FON Wi-Fi services - on the BT network, said the company.
John Petter, managing director for BT Retail Consumer, said, "Millions of BT Total Broadband customers already get free access to the UK's biggest Wi-Fi network. This free app makes accessing Wi-Fi so simple you don't even have to think about it.
"This represents real value to our customers at a time when more and more people are using their mobile phone to access the internet," he added.
The application also includes a mapping service, which is updated weekly.
BT Openzone is a Wi-Fi service that can be accessed in places such as airports, hotels, coffee shops, motorway service stations and city centres.
