Deutsche Telekom (DTEGn.DE) will consider any partner that can improve profitability at its U.S. operations, its chief executive told the company’s annual shareholders meeting. Chief Executive Tim Hoettges said on Thursday T-Mobile US (TMUS.N), of which Deutsche Telekom owns 66 percent, was in much better shape than two years ago. “But it is our duty to go on improving the return on T-Mobile US,” he added.
