T-Mobile’s parent company, Deutsche Telekom AG, has reportedly been discussing a potential merger with MetroPCS, according to Bloomberg. The talks come as T-Mobile continues to suffer from large subscriber defections, having lost 802,000 net customers in the fourth quarter of 2011 alone. Deutsche Telekom is considering a stock-swap transaction that would give the German company control over the combined entity, which would be publicly listed, although an outright sale of T-Mobile is possible too. T-Mobile, the nation’s fourth largest carrier, has been looking for options since its failed merger with AT&T last November. MetroPCS has 9.5 million subscribers as of January 2012 and operates the fifth largest wireless network in the United States.
