T-Mobile is a national provider of wireless voice, messaging and data services and is the U.S. operating entity of Deutsche Telekom, one of the largest telecommunications companies in the world. The Deal noted that if approved by regulators, the acquisition would “significantly reshape the U.S. wireless industry,” reducing the number of nationwide carriers from four to three and affecting the plans of competitors Sprint Nextel Corp. and Clearwire Corp.
