branding. Internet service Orange Polska's ADSL service in Poland is called Neostrada. The service is widely available throughout the country and is one of the most heavily subscribed to in Poland. Mobile network Orange Polska mobile was founded in December 1991 to operate an analogue (first-generation) network under the Centertel brand. It launched Idea, Poland's third GSM network, in 1998, operating on both the 900 and 1800-MHz bands from the beginning. Until 2001, when the analogue network was switched off, Idea was known as Idea Centertel, and former analogue customers were offered GSM contracts. Idea's slogan was Łączy Cię z ludźmi ("Connects you with people"). Idea adopted the Orange brand name in 2005, although the operating company was still formally known as PTK Centertel until 31 December 2013. It, along with parent company Orange Polska S.A., is controlled by Orange S.A. The brand change took place simultaneously on 19 September 2005. The company sponsored a free concert in Warsaw by British musician Sting on 24 September 2005 for 150,000 of its clients to publicise the changeover. The company also operates WLAN, 3G UMTS, 4G LTE and 5G NR networks in Poland. As of late 2011, the network had 14.7 million subscribers.
