A long-copy press ad, created by Wieden & Kennedy, highlights the internet capabilities the network provides its customers, including "Skyping your mum Happy Birthday from the top deck on the 47 bus" and "tweeting @justinbeiber from a festival Portaloo".
The campaign, which breaks this week and will run until mid-September, includes print, digital out of home, and online.
The agency's creative team included creative directors Dan Norris and Ray Shaugnessy, art director Freddie Powell and copywriter Hollie Walker. Media planning and buying was handled by Mindshare.
Wieden & Kennedy won the mobile network's £18m advertising account in January last year. It rolled out its first TV ad, 'drops'’, which promoted Three as "the fastest-growing mobile network" the following October.Follow @shearmans
