BT subscribers in London for the Olympic Games can take advantage of 500,000 wireless broadband hotpots in the city, it has been claimed.
In a Twitter message, the broadband provider explained that free Wi-Fi is available at half a million London locations.
A number of these hotspots are to be found in the Olympic Park, BT tweeted.
BT says it now offers more than six million Wi-Fi hotspots worldwide, four million of which are located in the UK.
These can be used for free by BT broadband subscribers - who simply need to use their email address and password to log in to the network.
"We believe your internet connection shouldn't stop when you leave your home," BT notes.
"Our Wi-Fi is totally free and unlimited at places like Starbucks, Welcome Break, Hilton, Network Rail, shopping centres, 12 major city centres and more."
BT says its customers can email, play games, work, catch up on TV, connect over social media and more, using a smartphone, tablet or laptop.
"There's no data allowance or tariffs with BT Wi-Fi," the firm explains.
