A1 Telekom Austria (A1, A eins) is the leading fixed and mobile network operator in Austria, with 5.4 million mobile and 2.3 million fixed-line customers. A1 Telekom Austria traces its origins to Austria's first GSM mobile phone network which began testing in 1992 and commercial operations in 1994, under the name Mobilkom Austria, then part of the Austrian state-owned PTT agency Post- und Telegraphenverwaltung [de] (PTV, ÖPT) until it was split off into its own company in 1996. After Mobilkom's merger with A1 Telekom Austria Group in July 2010 it operates under the new name of A1 Telekom Austria.
