T-Mobile USA

T-Mobile USA, the country's fourth-largest cellphone carrier, says it has completed its acquisition of MetroPCS.

T-Mobile, a subsidiary of Germany's Deutsche Telekom AG, will gain its own U.S. stock listing by merging with Dallas-based MetroPCS Communications Inc.

Washington state's chief prosecutor says there's a catch to T-Mobile's new cellphone plans, which replace the traditional two-year service contract with an installment plan for phone buyers.

One of the benefits of the new plan is that buyers can cancel their service at any time. But Washington Attorney General Bob Ferguson says the company hasn't told customers that they have to pay the full remaining cost of the phone if they cancel service; they can't remain on the installment plan.

Bellevue-based T-Mobile USA says Chief Executive Phillipp Humm is leaving to join his family back in Europe. An analyst says Humm was probably tired of the parent company not investing enough in its U.S. subsidiary.

Humm was appointed CEO of T-Mobile USA less than two years ago by its parent, Deutsche Telekom. Then, a few months later, AT&T announced that it was buying T-Mobile. That deal ultimately unraveled after the federal government challenged it.
