Mobile communication in Slovakia first became available in the early 1990s when the first NMT network operator, EuroTel Bratislava, a.s., a subsidiary of the then state owned Slovenské Telekomunikácie a.s. EuroTel, introduced the first GSM service to public in 1997. EuroTel was privatised together with its parent company and was rebranded as T-Mobile on 3 May 2005.
