MetroPCS shareholders have voted in favor of the company's merger with Deutsch Telekom, the parent company of T-Mobile, Reuters reported Wednesday, despite dissension from one of MetroPCS's largest shareholders. The shareholders' approval was the last obstacle T-Mobile and MetroPCS needed to pass in order to meld themselves into one carrier.

T-Mobile found itself on the other side of an acquisition two years ago, when AT&T attempted to buy the carrier but was blocked by US regulators. Since then, T-Mobile has made significant efforts to define and distinguish its business from competitors by moving away from contracts, making its services more inexpensive and creating a more flexible handset upgrade program.

The US Department of Justice, Federal Communications Commission, and Committee on Foreign Investment all approved the merger within the last few weeks. But the second largest shareholder, Paulson & Co., opposed the deal, and the Institutional Shareholder Services encouraged MetroPCS shareholders to block it, stating that MetroPCS is more than capable of sustaining its business.

Since the initial offer, Reuters reports that T-Mobile "sweetened its terms" for the acquisition, which may have swayed the largest shareholders.
