The brand blau (previously: blau Mobilfunk GmbH), is a mobile network brand owned by Telefonica Germany. The key brands are the discount tariff "blau.de" for calls within Germany and "blauworld" for calls outside Germany. The company was founded by three entrepreneurs, Martin Ostermayer, Thorsten Rehling and Dirk Freise in 2005. The money came from the sale of the website handy.de to Bertelsmann. A company for the distribution of mobile phone service with E-Plus was the base to establish Blau Mobilfunk GmbH as the first independent mobile phone discounter. More information...
