Exclusive: T-Mobile, Sprint parents consider dropping Huawei, see U.S. security clearance for deal - sources

WASHINGTON/NEW YORK (Reuters) - T-Mobile US Inc and Sprint Corp expect their merger to be approved by a U.S. national security panel as early as next week, after their respective parent companies said they would consider curbing their use of equipment from China's Huawei Technologies [HWT.UL], people familiar with the matter told Reuters.

U.S. government officials have been pressuring T-Mobile's German majority owner, Deutsche Telekom AG , to stop using Huawei equipment, the sources said, over concerns that Huawei is effectively controlled by the Chinese state and its network equipment may contain "back doors" that could enable cyber espionage, something which Huawei denies.

That pressure is part of the national security review of T-Mobile's $26 billion deal to buy U.S. rival Sprint, the sources said.

The Committee on Foreign Investment in the United States (CFIUS) has been conducting a national security review of the Sprint deal, which was announced in April. Negotiations between the two companies and the U.S. government have not been finalised and any deal could still fall through, the sources cautioned.

Sprint's parent, SoftBank Group Corp , plans to replace 4G network equipment from Huawei with hardware from Nokia and Ericsson , Nikkei reported on Thursday, without citing sources.

T-Mobile and Sprint shares were both down 1.2 percent on Friday.

Deutsche Telekom, Europe's largest telecoms company, on Friday said it was reviewing its vendor plans in Germany and other European markets where it operates, given the debate on the security of Chinese network gear.

Huawei has said the security concerns are unfounded. Tensions have been heightened by the arrest of Huawei's chief financial officer in Canada for possible extradition to the United States.

Sprint, T-Mobile, Deutsche Telekom, SoftBank and CFIUS declined to comment.
