The mobile giant will use Anastacia's sold-out Live at Last tour to promote its new F500i phone through product demonstrations, VIP parties and by allowing selected customers to meet Anastacia backstage.
Other activity includes in-store marketing and event hit squads, as well as an MMS tour diary, downloadable voicemails and live performance ringtones from the tour for its customers.
Steven Croix, global customer marketing director at Sony Ericsson, said: "Anastacia is a very exciting artist and is a perfect fit with F500i target audience."
Anastacia's European tour kicks off on the September 25 where she will visit cities in Germany, the Netherlands, Scandinavia, Austria, Italy, France, Switzerland, Belgium, Ireland and the UK.
Anastacia's unique blend of soul, pop and rock has ensured a string of top ten hits, including 'I'm Outta Love'.
