Thumbplay is an Internet-based platform for mobile content. The platform specializes in music. Members create accounts to have content delivered to their phones. 48000 is a dialing and messaging short code used when delivering your monthly billing message.
Thumbplay differs from Zune and others in that you can download your music to virtually any mobile device, PC or Mac. You don’t have to buy a specialized device. For a monthly fee starting at $9.99 as of January 2011, you have access to unlimited music through Thumbplay.
In 2009, "Billboard Magazine" revealed that Thumbplay provides a platform that allows labels flexibility in selling ringtones anywhere on the net. Thumbplay provides a central location for labels to distribute content that can be played on iPhones, Androids, Blackberries, PCs and Macs.
