T-Mobile US is one of the largest providers of wireless voice and data communications services in the US. The company’s 61 million T-Mobile and MetroPCS contract and prepaid consumer customers use its networks domestically and are able to connect to the compatible network of Deutsche Telekom when in Europe. It also offers low-cost, no-contract mobile services through the GoSmart brand. In addition, T-Mobile sells phones, tablets, PDAs, and accessories from such vendors as Apple, Nokia, and Samsung. It has about 8,000 T-Mobile and MetroPCS branded retail sites. In 2013 Deutsche Telekom acquired smaller rival MetroPCS via a reverse merger and combined it with T-Mobile; Deutsche Telekom owns about two-thirds of the combined company.
