The service, which can be used on any WAP-enabled handset, will give access to a special "Kerrang! Legends of Rock" site, which features information on dozens of bands from the Red Hot Chilli Peppers to Green Day.
As well as facts and figures, fans will also be able to access exclusive pictures, mobile downloads and ringtones.
Kerrang! Radio's programme director, Adam Uytman, said: "Radio is no longer solely consumed through conventional channels. The launch of the Kerrang! Radio WAP site is a brand extension that adds another dimension for listeners, taking them closer to the music they love."
