Telekomunikacja Polska was established in December 1991 as a joint stock company under the control of the State Treasury, following the split-up of the communist era state-owned PTT entity Polish Post, Telegraph and Telephone [pl].

The tribunal said the company had improperly calculated what it owed DPTG for a fiber-optic transmission system the venture installed in 1991.

TPSA has not paid the first award and has filed a complaint about the arbitration, while GN has started enforcement proceedings in Poland and the Netherlands.

Orange Polska mobile was founded in December 1991 to operate an analogue (first-generation) network under the Centertel brand.

Idea adopted the Orange brand name in 2005, although the operating company was still legally called PTK Centertel until 31 December 2013.

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.
