Nokia, already offering similar services to E-Plus network, acquired by Telefonica Germany in 2014, will now extend the management tool offerings, processes and expertise in a phased approach, with development of a simplified management structure to Telefonica Germany's entire mobile access, core and fixed network operations, since September this year, claiming to increase quality and efficiency in the process. "Levering Nokia's expertise as a managed service supplier across our entire network will allow us to simplify operations and enhance performance and quality, allowing us to concentrate on delivering an outstanding subscriber experience across Germany," said Cayetano Carbajo Martin, chief technology officer at Telefonica Germany. Telefonica Germany, with a nationwide fixed and mobile network and 43.0 million lines, is the market leader with a net 48 million customer lines in Germany.
