T-Mobile USA CEO resigns

With Philipp Humm's departure, Jim Alling steps in on an interim basis.

After two years at the top, Philipp Humm has left his position as CEO of T-Mobile USA to head Vodafone's northern and central Europe division. Humm joined T-Mobile's parent company, Deutsche Telekom, in 2005.

Jim Alling, currently COO of T-Mobile USA, will take over Humm's duties on an interim basis while a search for new CEO is underway.

René Obermann, CEO of Deutsche Telekom, said:

Philipp Humm has given the company some important initiatives over the past years. Under his leadership, the cost situation at T-Mobile USA has vastly improved and he led the company during a difficult phase regarding the planned merger with AT&T. Now we need somebody who can convert initiatives into market successes.
