Motorola, the US mobile phone giant, has announced a review of its £266m global media buying account as it tries to close the sales gap on rivals Nokia and Ericsson.
Its media account is currently with Universal McCann and the company says it will decide the account by early March.
It would not reveal which media agencies will be involved in the pitch.
In September the company consolidated its creative advertising account and moved all work to Ogilvy & Mather New York, which meant that McCann Erickson-Worldwide and Leo Burnett were thrown off the roster.
Motorola is striving to catch up with Finland's Nokia and Sweden's Ericsson in the race to sell mobile handsets. This afternoon it is expected to announce that fourth quarter earnings that are at least 40% down on last year.
While Nokia continues to grow sales by around 36% a year, Motorola's figure is closer to 7%.
The battleground will increasingly move from standard phone handsets towards Wap and next-generation digital technologies.
