Carat pitched against Publicis Groupe's ZenithOptimedia, Mediabrands' UM, Omnicom's PHD and WPP's incumbent agency MediaCom over a three month process.
The account includes £22m in UK billings and will be handled by Carat from September.
The appointment follows a review of all of Nokia's marketing services in last year. Wieden & Kennedy won its global advertising account for its Nseries range and Aegis Group's Isobar and US incumbent R/GA split its global digital advertising business.
