O2 has signed 10-year deal with McDonald's to provide free Wi-Fi access in 1,200 of its restaurants.
The firm said that the switch over from previous provider, The Cloud, to O2 will take place in time for 'this summer's festivities' including the Olympics and the Queen's diamond jubilee.
The move adds McDonald's to a list of firms which O2 provides internet for including Mitchells & Butlers, House of Fraser and Westminster Council.
Mark Fabes, IT Director at McDonald's said: "Recent figures showed that a staggering 750,000 McDonald's customers are logging on in our restaurants each month and we are always looking for ways to improve our customer experience."
"For the 3 million people we serve in our restaurants each day we believe that O2's mobile expertise and enhanced quality of network connectivity will deliver a fast, safe and secure service for our customers to use when they visit us."
A spokesman for O2 said: "This announcement builds on the significant partnerships already secured by O2 Wifi in the past 12 months, enabling millions of people the length and breadth of the UK to access the internet for free whilst on the move."
Access to the Wi-Fi hotspots will be free to McDonald's customers whether they are an O2 customer or not. A simple one-time sign-up process is all that will required to get online in different branches or other O2 hotspots.
O2 said: "All hotspots will be premium public hotspots, as opposed to using residential connections with limited bandwidth."
