The campaign enables 3G handset owners to directly access video and audio excerpts of their last single, Forever Lost, and the current single, Love Me Like You, from TK poster sites.
Fans can also buy a selection of the band's official ring tones.
The campaign was launched on promotional posters for The Magic Numbers' debut album.
Consumers are prompted to dial a short code, which streams a 30-second video or audio clip back to their mobile. Eric Winbolt, digital media manager, EMI, said: "This campaign is about providing a more interactive print experience for consumers and making print media work a bit harder."
