MetroPCS (stylized as metroPCS) is a prepaid wireless service in the United States that is part of T-Mobile US, Inc.. MetroPCS provides nationwide talk, text, and data depending on the plan services using GSM, HSPA, HSPA+ and 4G LTE networks. MetroPCS previously operated the sixth largest mobile telecommunications network in the United States using code division multiple access (CDMA) technology. The legacy MetroPCS CDMA network was decommissioned on June 21, 2015.[2] Its legacy 4G network using LTE will be integrated with T-Mobile US own 4G LTE network. In October 2012, MetroPCS Communications reached an agreement to merge with T-Mobile USA, Inc., a deal that would "help the competing provider become more competitive with the other National Carriers".[3] The deal was a reverse merger for MetroPCS; following the closure of the merger on May 1, 2013, the combined company, now known as T-Mobile US, Inc., began trading on the New York Stock Exchange as TMUS
