(Reuters) - Dish Network Corp's <DISH.O> chairman, Charlie Ergen, recently contacted Deutsche Telekom AG <DTEGn.DE> to express interest in acquiring the German company's unit, T-Mobile US Inc <TMUS.N>, Bloomberg reported, citing people with knowledge of the matter.
Ergen has not made a formal offer or hired any bank to advise it on the potential deal, the report said.
Dish has told Deutsche Telekom, which owns about two-thirds of T-Mobile, that it may be interested in a deal after a November auction for wireless airwaves is completed, the report added. (http://bloom.bg/1uoZ1YB)
Deutsche Telekom views potential offers valuing T-Mobile at $35 a share as being substantially too low, Reuters reported last week, countering a Bloomberg report.
Earlier in August, Sprint Corp <S.N> dropped its bid to acquire T-Mobile in the face of continuing regulatory resistance despite months of lobbying.
Dish declined to comment and T-Mobile, the No. 4 U.S. carrier, could not be immediately reached for comment.
