T-Mobile Polska S.A. is a Polish mobile phone network operator. The company was formerly named Polska Telefonia Cyfrowa (lit. "Polish Digital Telephony") and operated under the name Era, until being rebranded as T-Mobile on 5 June 2011. As in other European countries, the company operates a GSM (2G, 4G LTE and 5G NR) network. Following a decade-long ownership dispute with the French Vivendi corporation, the company has been wholly owned by the German telecommunications provider Deutsche Telekom since 2010.
