The agency beat JWT and Mother in a protracted pitch process that began in January.
Up until now, the lion's share of Nokia's £15 million UK business has been handled by Grey, which works on mobile phones, enterprise solutions and networks. Lowe services a portion of the brand's handset advertising, and is unaffected by the review.
DDB, JWT and Bates Asia/Grey are still in the contest to handle network distribution for the global account. A decision is expected in two weeks. The winning network for distribution will also be tasked with adapting ads for local markets.
Six shortlisted agencies were briefed in Helsinki at the start of March before the business was split into two parts in April. These included WPP Group's Grey Global, JWT and Asian incumbent BatesAsia; Omnicom's DDB Worldwide and Bartle Bogle Hegarty.
Earlier this year, Wieden & Kennedy was awarded the brief to globally launch Nokia's concept stores after pitching against Grey last December.
Media is handled by MediaCom and unaffected by the creative review.
