The appointment puts BBH in a strong position to take the lead role in developing advertising creative and strategy for Vodafone's global brand campaigns. The mobile operator spends £38m in the UK alone, according to Nielsen Media Research.
BBH, which created the "Who would you like to have a One 2 One with?" ads for what is now T-Mobile, will sit beside Vodafone's lead creative agency Wieden & Kennedy Amsterdam. W&K is believed to have struggled with the workload over the past year.
David Wheldon, global director of marketing and brand communications at Vodafone, said the appointment was a sign of the company's development.
The appointment will not affect J Walter Thompson, which handles the local market roll-out of international campaigns.
Last month, David Beckham agreed a further one-year contract with Vodafone, reported to be worth £1m.
BBH also handles the global ad account for handset manufacturer Sony Ericsson.
