International wireless operator T-Mobile and handset manufacturer Sony Ericsson have joined forces to launch a pan-European promotional campaign centering on a tour of electronic-music festivals.

The partnership is backing a series of “Electronic Beats” festivals this summer, beginning June 13 in Cologne, Germany. The tour will continue in Scotland, Austria and the Netherlands. All dates will be announced in the coming weeks.

T-Mobile founded the “Electronic Beats” brand in 2001. This year's series is the most extensive of the T-Mobile festival tours to date.

"For the past four years, we have committed ourselves to not only supporting the electronic music genre, but also becoming a key influencer within this music community,” says Reinhard Pluckthun, T-Mobile International's VP sponsoring.

The festival campaign will also be used to promote the new Sony Ericsson D750i handset. The phone -- which will feature an MP3 player, an FM radio and a two mega-pixel camera -- goes on sale this June in the United Kingdom for £119.99 ($220). Sony Ericsson says similar prices will apply in other European markets.

Exclusive to T-Mobile's European subscribers, the device will come pre-installed with the operator's Mobile Jukebox software for accessing music-related content on its t-zone Web service.

Supporting the festivals and handset will be a new free quarterly “electronic beats” print magazine. It will be distributed at clubs, restaurants and hotels.
