T-Mobile USA, a subsidiary of Germany-based Deutsche Telekom, is one of the largest providers of wireless voice and data communications services in the US. The company's 43 million+ T-Mobile and MetroPCS contract and prepaid consumer customers use its networks domestically and are able to connect to the compatible network of its parent company when in Europe. It also provides wireless Internet access and other data services in airports and retail businesses, among other locations, through its T-Mobile HotSpot brand. T-Mobile resells phones, PDAs, and accessories from such vendors as Nokia and Samsung. In 2013 Deutsche Telekom acquired smaller rival MetroPCS via a reverse merger and combined it with T-Mobile.
