Vodafone had narrowed down its shortlist of six agencies to the final pair in the review, which was handled by search consultancy Agency Insight.
The review was called at the end of January and follows an internal restructure at Vodafone, which saw marketing functions for its corporate and SME business-to-business divisions combined.
Vodafone said that its consumer direct marketing account would remain with Harrison Troughton Wunderman despite speculation to the contrary.
Phil Andrews, managing partner at Partners Andrews Aldridge, said: "Our appointment by Vodafone continues a very successful first half to the year.
"It is testament to our skills in business to business CRM and is a great win for the agency."
The agency won a place on Sky's roster in February and was named Marketing's direct agency of 2004.
