Sprint is “working toward a possible bid” for T-Mobile, the Wall Street Journal reports. It’s noted the deal could be worth more than $20 billion. An approved deal would preserve Sprint’s status as the third largest carrier behind Verizon and AT&T, but up its subscriber count to 53 million postpaid customers. However, former antitrust officials said the government would be “very wary” of such an acquisition. AT&T’s attempt to acquire T-Mobile in 2011 was abandoned after the Department of Justice moved to block the merger; a merger with Sprint would not as radically change the competitive landscape.
