Movistar in Chile has introduced what it says are Latin America's first unlimited mobile music downloads.

The catalog contains music from Universal and Warner for "dual delivery" to both cell phone and computer, for a fixed monthly rate of about $7.50 a month, Aliado Digital reports.

The DRM-protected tracks are blocked once the user stops the subscription, but individual mobile downloads can be purchased for about $2.10 each.

The move by Telefonica's Movistar comes after the launch of a digital music store by wireless carrier Comcel in Colombia.
