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.[2]
History
Polska Telefonia Cyfrowa was founded as a company in December 1995, and on 26 February 1996 it won a license to provide telecommunications services paging number 602 and permission to build a mobile radio communication network according to the GSM standard in the 900 MHz band, which was later extended to GSM 1800 MHz. The first test (non-commercial) base stations were launched during the International Trade Fair in June 1996 and a few base stations in Warsaw. The commercial launch of the network took place on 16 September 1996.
At the end of 2004, Era had over 8.6 million customers and was the largest mobile phone network operator in Central Europe
