Telekom Romania is a telecommunications company operating in Romania. It was launched as Cosmorom in 1999 by Romtelecom and commenced service in April 2000. In 2004, Romtelecom decided to sell a majority stake in the company, which was eventually bought by the Greek company OTE, leaving Romtelecom with the remaining 30%.
In July 2005, OTE's mobile division Cosmote relaunched the mobile operator separate from the fixed services company Romtelecom. On 12 September 2014, Romtelecom and Cosmote Romania unified mobile and fixed services under a single brand and changed their respective legal names to Telekom Romania Communications and Telekom Romania Mobile Communications. The companies were majority owned by OTE, which in turn is controlled by Deutsche Telekom. On November 6, 2020, OTE agreed to sell the 54% stake in Telekom Romania Communications to Orange Romania. However, OTE retained Telekom Romania Mobile in its portfolio.
