T-Mo USA chief quits

Phillip Humm, the chief executive of T-Mobile USA, is quitting the firm after 18 months in the role.
Chief operating officer Jim Alling is taking the reins of the US division on a temporary basis until a permanent replacement can be found to replace Humm, who is standing down to spend more time with his family. The outgoing chief joined parent firm Deutsche Telekom in 2005, but moved to the troubled US business in May 2010, before taking control of the operation in November 2010.
Humm oversaw the failed attempt to merge T-Mobile USA with AT&T last year, however Deutsche Telekom chief René Obermann praised his leadership during the attempted sale and notes the “cost situation at T-Mobile USA has vastly improved,” during his tenure.
Obermann says the firm will look for someone “who can convert initiatives into market successes,” to replace the outgoing chief.
